Introduction

Scope of Manual

This instruction manual includes installation, maintenance, and parts information for the Fisher NotchFlo DST control valve. Refer to separate manuals for instructions covering the actuator, positioner, and accessories.

Do not install, operate, or maintain NotchFlo DST valves without being fully trained and qualified in valve, actuator, and accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important to carefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If you have any questions about these instructions, contact your Emerson Process Management sales office before proceeding.

Description

The NotchFlo DST globe (figure 1) and angle valves have metal seats, cage guiding, quick change trim, and push-down-to-close valve plug action. All available valve sizes and pressure ratings use balanced valve plugs with the exception of CL900 and CL1500 (NPS 1 and 1-1/2 valves) which use an unbalanced valve plug. To provide a seal between the cage and a balanced valve plug, the balanced valve plugs use a pressure-assisted spring-loaded seal ring.

A properly sized NotchFlo DST valve with 3-, 4-, or 6-stage dirty service anti-cavitation trim (figure 2) offers excellent control of high pressure drop liquids with entrained solids, while avoiding the damaging effects of cavitation and erosive solids.

Figure 2. Fisher NotchFlo DST Trim

W8538-1

NotchFlo DST control valves utilize a high resistance, multi-stage, axial flow path (or passage) where fluid flow is parallel to the axis of the plug and cage.

Pressure reduction occurs throughout the length of the plug; thus individual stages aren't exposed to the full pressure differential. Therefore, trim life is enhanced.

NotchFlo DST trim utilizes a series of notched flow restrictions and expansions to control the pressure drop of the fluid.

The amount of pressure drop per stage is controlled to prevent cavitation problems and minimize erosion issues.

Flow passage configuration provided by the multi-stage plug and cage design make the NotchFlo DST valves well-suited for applications involving fluids with entrained particles. This is a potentially serious problem for other anti-cavitation valve designs which are subject to clogged flow passages.

Design of the trim allows for high rangeability.

Installation

WARNING

Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal injury.

Personal injury or property damage caused by sudden release of pressure may result if the valve assembly is installed where service conditions could exceed the limits given in table 1 or on the appropriate nameplates. To avoid such injury or damage, provide a relief valve for over-pressure protection as required by government or accepted industry codes and good engineering practices.

Check with your process or safety engineer for any additional measures that must be taken to protect against process media.

If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this instruction manual.

WARNING

Some bonnet flanges have a tapped hole that was used to handle the bonnet during manufacture. Since this tapped hole was not designed or intended to support the weight of the valve/bonnet assembly, do not use this tapped hole to lift the valve assembly or personal injury may result from the assembly falling.

CAUTION

When ordered, the valve configuration and construction materials were selected to meet particular pressure, temperature, pressure drop, and controlled fluid conditions. Since some body/trim material combinations are limited in their pressure drop and temperature ranges, do not apply any other conditions to the valve without first checking with your Emerson

Process Management sales office.

1. Before installing the valve, inspect it to ensure that the valve body cavity is free of foreign material.

2. Clean out all pipelines to remove scale, welding slag, and other foreign materials before installing the valve.

3. Flow through the valve must be in the direction indicated by the flow arrow, which is cast on or attached to the valve body.

4. Use accepted piping practices when installing the valve in the pipeline. For flanged valve bodies, use a suitable gasket between the body and pipeline flanges.

4

Instruction Manual

D103211X012

5. Install a three-valve bypass around the valve if continuous operation is required during maintenance.

6. If the actuator and valve body are shipped separately, refer to the actuator mounting procedure in the appropriate actuator instruction manual.

7. If the valve body was shipped without packing installed in the packing box, install the packing before putting the valve body into service. Refer to instructions given in the Packing Maintenance procedure.

WARNING

Personal injury could result from packing leakage. Valve packing was tightened prior to shipment; however, the packing might require some readjustment to meet specific service conditions. Check with your process or safety engineer for any additional measures that must be taken to protect against process media.

Maintenance

Refer to figure 10 through 16.

Valve parts are subject to normal wear and must be inspected and replaced as necessary. Inspection and maintenance frequency depends on the severity of service conditions. This section includes instructions for packing maintenance and trim maintenance. All maintenance operations may be performed with the valve in the line.

WARNING

Avoid personal injury or damage to property from sudden release of pressure or uncontrolled process fluid. Before starting disassembly:

D

Do not remove the actuator from the valve while the valve is still pressurized.

D

Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal injury.

D

Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the actuator cannot suddenly open or close the valve.

D

Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure on both sides of the valve. Drain the process media from both sides of the valve.

D

Vent the power actuator loading pressure and relieve any actuator spring precompression.

D

Use lock-out procedures to be sure that the above measures stay in effect while you work on the equipment.

D

The valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the

pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings, or when loosening the packing box pipe plug.

D

Check with your process or safety engineer for any additional measures that must be taken to protect against process media.

CAUTION

The NotchFlo DST valve uses spiral-wound gaskets which are crushed to provide their seal. A spiral-wound gasket should never be reused. Whenever a gasket seal is disturbed by removing or shifting gasketed parts, a new gasket must be installed upon reassembly. This is necessary to ensure a good gasket seal, since the used gasket will not seal properly.

The spiral-wound gaskets are of special design. Failure to use genuine Fisher replacement parts may result in valve damage and/or failure.

Packing Maintenance

Key numbers refer to figure 3 for PTFE V-ring packing and to figure 4 and 5 for graphite ribbon/filament and graphite

ULF packing, unless otherwise indicated.

WARNING

To avoid personal injury or equipment damage resulting from packing leakage, inspect the valve plug stem and packing box wall for nicks or scratches while performing the following procedures.

Use care to avoid damaging these surfaces.

For spring-loaded single PTFE V-ring packing, the spring (key 24) maintains a sealing force on the packing. If leakage is noted around the packing follower (key 28), check to be sure the shoulder on the packing follower is touching the bonnet. If the shoulder is not touching the bonnet, tighten the packing flange nuts (key 21, figure 10 through 16) until the shoulder is against the bonnet. If leakage cannot be stopped in this manner, proceed to the Replacing Packing procedure.

If there is undesirable packing leakage with other than spring-loaded PTFE V-ring packing, first try to limit the leakage and establish a stem seal by tightening the packing flange nuts (key 21, figure 10 through 16) to at least the minimum recommended torque in table 3 or 4. However, do not exceed the maximum recommended torque in table 3 or 4. or excessive friction may result. If leakage continues, replace the packing by following the numbered steps presented in the Replacing Packing procedure.

If the packing is relatively new and tight on the valve plug stem, and if tightening the packing flange nuts does not stop the leakage, it is possible that the stem is worn or nicked so that a seal cannot be made. The surface finish of a new stem is critical for making a good packing seal. If the leakage comes from the outside diameter of the packing, it is possible that the leakage is caused by nicks or scratches around the packing box wall. While replacing the packing according to the Replacing Packing procedure, inspect the valve plug stem and packing box wall for nicks or scratches.

Adding Packing Rings

WARNING

Refer to the WARNING at the beginning of the Maintenance section in this instruction manual.

To avoid personal injury or equipment damage resulting from packing leakage, inspect the valve plug stem and packing box wall for nicks or scratches while performing the following procedures.

Use care to avoid damaging these surfaces.

Key numbers referred to in this procedure are shown in figures 10 through 16, unless otherwise indicated.

When using packing with a lantern ring (key 24) it may be possible to add packing rings above the lantern ring as a temporary measure without removing the actuator from the valve body.

1. Isolate the control valve from the line pressure, release pressure from both sides of the valve body, and drain the process media from both sides of the valve. If using a power actuator, also shut-off all pressure lines to the power actuator, release all pressure from the actuator. Use lock-out procedures to be sure that the above measures stay in effect while you work on the equipment.

2. Remove the packing flange nuts (key 21) and lift the packing flange, upper wiper, and packing follower (keys 19, 27, and 28) away from the valve body.

3. It may be possible to dig out the old packing rings on top of the lantern ring, but use care to avoid scratching the valve plug stem or packing box wall. Clean all metal parts to remove particles that would prevent the packing from sealing.

4. Remove the stem connector and slip the packing rings over the end of the valve plug stem.

5. Reassemble the packing follower, upper wiper, packing flange, and packing flange nuts (keys 28, 27, 19, and 21).

6. Reconnect the body-actuator stem connection according to the appropriate actuator instruction manual.

7. Tighten the packing flange nuts only far enough to stop leakage under operating conditions. Check for leakage around the packing follower when the valve is being put into service. Retighten the packing flange nuts as required

(see table 3 or 4).

Replacing Packing

WARNING

Refer to the WARNING at the beginning of the Maintenance section in this instruction manual.

To avoid personal injury or equipment damage resulting from packing leakage, inspect the valve plug stem and packing box wall for nicks or scratches while performing the following procedures.

Use care to avoid damaging these surfaces.

Key numbers referred to in this procedure are shown in figures 10 through 16, unless otherwise indicated.

1. Isolate the control valve from the line pressure, release pressure from both sides of the valve body, and drain the process media from both sides of the valve. If using a power actuator, also shut-off all pressure lines to the power actuator, release all pressure from the actuator. Use lock-out procedures to be sure that the above measures stay in effect while you work on the equipment.

2. Remove the cap screws in the stem connector, and separate the two halves of the stem connector. Then exhaust all actuator pressure, if any was applied, and disconnect the actuator supply and any leakoff piping.

3. Remove either the yoke locknut (key 32) or the hex nuts (key 30), and remove the actuator from the bonnet (key

18).

D103211X012

4. Loosen the packing flange nuts (key 21) so that the packing (keys 22, 23, 209, or 210, figures 3, 4, or 5) is not tight on the valve plug stem (key 6). Remove any travel indicator disk and stem locknuts from the valve plug stem threads.

CAUTION

When lifting the bonnet (key 18), be sure that the valve plug and stem assembly (keys 5 and 6) remains on the seat ring

(key 4). This avoids damage to the seating surfaces as a result of the assembly dropping from the bonnet after being lifted part way out. The parts are also easier to handle separately.

Use care to avoid damaging gasket sealing surfaces.

WARNING

To avoid personal injury or property damage caused by uncontrolled movement of the bonnet, loosen the bonnet by following the instructions in the next step. Do not remove a stuck bonnet by pulling on it with equipment that can stretch or store energy in any other manner. The sudden release of stored energy can cause uncontrolled movement of the bonnet.

If the cage sticks to the bonnet, proceed carefully with bonnet removal and support the cage so that it will not fall unexpectedly from the bonnet.

Note

The following step also provides additional assurance that the valve body fluid pressure has been relieved.

5. Hex nuts (key 14) attach the bonnet to the valve body. Loosen these nuts approximately 3 mm (1/8 inch). Then loosen the body-to-bonnet gasketed joint by either rocking the bonnet or prying between the bonnet and valve body. Work the prying tool around the bonnet until the bonnet loosens. If no fluid leaks from the joint, proceed to the next step. If fluid leaks from the joint, the process pressure was not relieved from the valve as noted in the

Warning at the beginning of the Maintenance section in this manual.

6. Unscrew the hex nuts (key 14) and carefully lift the bonnet off the valve stem. If the valve plug and stem assembly starts to lift with the bonnet, use a brass or lead hammer on the end of the stem and tap it back down. Set the bonnet on a cardboard or wooden surface to prevent damage to the bonnet gasket surface.

7. Remove the valve plug (key 5), bonnet gasket (key 11), cage (key 2), cage gaskets (if applicable) (key 65), seat ring

(key 4), and the seat ring gasket(s) (key 12).

CAUTION

Inspect the seat ring, cage, bonnet, and body gasket surfaces. These surfaces must be in good condition, with all foreign material removed. Small burrs less than approximately 0.076 mm (0.003 inch) in height (the thickness of a human hair) can be ignored. Scratches or burrs that run across the serrations are not permitted under any conditions, since they will prevent the gaskets from sealing properly.

8. Clean all gasket surfaces with a good wire brush. Clean in the same direction as the surface serrations, not across them.

9. Cover the opening in the valve body to protect the gasket surface and to prevent foreign material from getting into the valve body cavity.

10. Remove the packing flange nuts (key 21), packing flange (key 19), upper wiper (key 27), and packing follower (key

28). Carefully push out all the remaining packing parts from the valve side of the bonnet using a rounded rod or other tool that will not scratch the packing box wall.

11. Clean the packing box and the following metal packing parts: packing follower, packing box ring (key 26), spring or lantern ring (key 24), and, for single arrangements of PTFE V-ring packing only, special washer (key 25).

12. Inspect the valve stem threads for any sharp edges that might cut the packing. A whetstone or emery cloth may be used to smooth the threads if necessary.

13. Remove the protective covering from the valve body cavity, and install the seat ring and cage using new seat ring gasket(s) (key 12), bonnet gasket (key 11), and cage gaskets (if applicable) (key 65). Install the plug, then slide the bonnet over the stem and onto the studs (key 13).

Note

The prelubricated hex nuts (key 14) referred to in step 14 can be identified by a black film coating on the nut threads.

The proper bolting procedures in step 14 include--but are not limited to--ensuring that the bonnet stud threads are clean, and that the hex nuts are evenly tightened to the specified torque values.

CAUTION

Failure to comply with good bonnet-to-body bolting practices and the torque values shown in tables 5, 6, and 7 may result in damage to the valve. Cheater bars or slug wrenches should not be used for this procedure.

Hot torquing is not recommended on CL900, CL1500, and CL2500 valves. When operating temperature has been reached, perform this torquing procedure once again on CL600 valves.

Note

Stud(s) and nut(s) should be installed such that the manufacturer's trademark and material grade marking is visible, allowing easy comparison to the materials selected and documented in the Emerson/Fisher serial card provided with this product.

WARNING

Personal injury or damage to equipment could occur if improper stud and nut materials or parts are used. Do not operate or assemble this product with stud(s) and nut(s) that are not approved by Emerson/Fisher engineering and/or listed on the serial card provided with this product. Use of unapproved materials and parts could lead to stresses exceeding the design

or code limits intended for this particular service. Install studs with the material grade and manufacturer's identification mark visible. Contact your Emerson Process Management representative immediately if a discrepancy between actual parts and approved parts is suspected.

14. Lubricate the stud threads and the faces of the hex nuts (key 14) with anti-seize lubricant (not necessary if new factory prelubricated hex nuts are used). Install the hex nuts and tighten them finger-tight. Stroke the valve several times to center the trim. Torque the nuts in a crisscross pattern to no more than 1/4 of the nominal torque value specified in tables 5, 6, and 7.

When all nuts are tightened to that torque value, increase the torque by 1/4 of the specified nominal torque and repeat the crisscross pattern. Repeat this procedure until all nuts are tightened to the specified nominal value. Apply the final torque value again and, if any nut still turns, tighten every nut again.

Note

When installing packing rings, prevent entrapping air between the rings. Add the rings one at a time without forcing them below the chamfer of the packing box entrance chamber. As each successive ring is added, the stack should not be pushed down more than the thickness of the added ring (figure 6).

15. Install new packing and the metal packing box parts according to the appropriate arrangement in figures 3, 4, or 5.

If desired, packing parts may be pre-lubricated with a silicon base grease for easier installation. Slip a smooth-edged pipe over the valve stem, and gently tap each soft packing part into the packing box, being sure that air is not trapped between adjacent soft parts.

16. Slide the packing follower, wiper, and packing flange into position. Lubricate the packing flange studs (key 20) and the faces of the packing flange nuts (key 21). Install the packing flange nuts.

For the spring-loaded PTFE V-ring packing shown in figure 3, tighten the packing flange nuts until the shoulder on the packing follower (key 28) contacts the bonnet.

Note

Lubrication is not recommended on graphite packing.

For graphite packing, tighten the packing flange nuts to the maximum recommended torque shown in table 3 or 4.

Then, loosen the packing flange nuts, and retighten them to the recommended minimum torque shown in table 3 or 4.

For other packing types, tighten the packing flange nuts alternately in small equal increments until one of the nuts reaches the minimum recommended torque shown in table 3 or 4. Then, tighten the remaining flange nuts until the packing flange is level and at a 90-degree angle to the valve stem.

17. Mount the actuator on the valve body assembly, and reconnect the actuator and valve plug stems according to the procedures in the appropriate actuator instruction manual.

Trim Removal

Key numbers referenced in this procedure are shown in figures 10 through 16, except where indicated.

1. Remove the actuator and bonnet by following steps 1 through 6 of the replacing packing procedure. Observe all warnings and cautions in that procedure.

12

2. Lift the valve stem and attached valve plug out of the valve body. If the valve plug is to be reused, tape or otherwise protect the valve plug stem and the valve plug seating surface to prevent scratches.

3. Lift out the cage (key 2), the bonnet gasket (key 11), and (if applicable) the cage gaskets (key 65).

4. Remove the seat ring (key 4) and the seat ring gasket(s) (key 12).

5. Inspect the parts for wear or damage and replace if needed.

6. Refer to the Valve Plug Maintenance procedure or to the Lapping Seats procedure.

Valve Plug Maintenance

Key numbers used in this procedure are shown in figures 10 through 16, except where indicated.

1. With the valve plug (key 5) removed according to the trim removal procedure, proceed as appropriate:

For the NPS 1 and 1-1/2 CL900 or 1500 NotchFlo DST valves, proceed to step 2.

For all other NotchFlo DST valves, work the retaining ring (key 10) off the valve plug with a screwdriver. Carefully slide the backup ring, seal ring, and anti-extrusion rings (keys 9, 8, and 63) off the valve plug.

2. To replace the valve plug stem (key 6), drive out the pin (key 7), and unscrew the stem from the valve plug.

CAUTION

Never reuse an old stem with a new valve plug. Using an old stem with a new plug requires drilling a new pin hole in the stem. This weakens the stem and may cause the stem to fail in service. If a new valve plug is required, always order a valve plug, stem, and pin as an assembly. Specify the correct part number of each of the three parts, but state that the parts are being ordered as an assembly.

A used valve plug may be reused with a new stem.

3. Thread the new stem into the valve plug and tighten it to the appropriate torque value given in table 8. Using the valve plug pin hole as a guide, drill the pin hole through the stem. Refer to table 8 for drill sizes.

4. Drive in the pin to lock the assembly.

5. If it is necessary to lap the seating surfaces, complete the lapping seats procedure before installing the seal ring. The

Trim Replacement procedure provides seal ring installation instructions and valve reassembly instructions.

Lapping Seats

Key numbers referenced in this procedure are shown in figures 10 through 16, except where indicated.

With metal-seat constructions, lapping seating surfaces of the valve plug and seat ring (keys 5 and 4) can improve shutoff. (Deep nicks should be machined out rather than ground out.) Use a good quality lapping compound of a mixture of 280 to 600-grit. Apply the compound to the bottom of the valve plug.

Note

NotchFlo DST valves use spiral-wound gaskets. These gaskets provide their seal by being crushed and therefore should never be reused. This includes reusing a gasket after the lapping procedure has been performed.

An “old” gasket can be used to lap the seat, however the gasket must be replaced with a new gasket.

To preserve the effects of lapping, do not change either the position of the seat ring in the valve body cavity or the position of the cage on the seat ring after lapping the seating surfaces. When the parts are removed for cleaning and replacement of the “old” gaskets, return them to the original positions.

13

NotchFlo DST Valve

October 2014

Use the following procedure to lap the seating surfaces.

1. Install the following parts according to the instructions presented in the trim replacement procedure: “old” seat ring gasket(s) (key 12), seat ring (key 4), cage (key 2), “old” bonnet gasket(key 11), and (if applicable) the “old” cage gaskets (key 65).

2. Proceed as appropriate:

For a NotchFlo DST balanced valve, install the valve plug and stem assembly (keys 5 and 6)--without seal ring

(key 8)--into the cage.

For a NotchFlo DST unbalanced valve, install the valve plug and stem assembly (keys 5 and 6) into the cage.

3. Install the bonnet (key 18) over the valve stem, and secure the bonnet with four of the hex nuts (key 14).

4. Attach a handle, such as a piece of strap iron secured by stem locknuts, to the valve stem. Rotate the handle alternately in each direction to lap the seats.

5. After lapping, disassemble as necessary (you may mark the position of the seat ring and cage with a soft tip marker). Clean the seating surfaces, replace the gaskets, reassemble (taking care to return the seat ring and cage to their original positions), and test for shutoff. Repeat the lapping procedure if necessary.

Trim Replacement

WARNING

Observe the warning at the start of the Maintenance section.

After all trim maintenance has been completed, reassemble the valve body by following the numbered steps below. Be certain that all gasketed surfaces have been well cleaned. Key numbers referenced in this procedure are shown in figures 10 through 16, except where indicated.

CAUTION

Inspect the seat ring, cage, bonnet, and body gasket surfaces. These surfaces must be in good condition, with all foreign material removed. Small burrs less than approximately 0.076 mm (0.003 inches) in height (the thickness of a human hair) can be ignored. Scratches or burrs that run across the serrations are not permitted under any conditions, since they will prevent the gaskets from sealing properly.

1. Install the seat ring gasket (key 12) into the valve body. Install the seat ring (key 4).

2. For CL600, CL900, and CL1500 ≤ NPS 4 valves, install the second seat ring gasket (key 12) onto the seat ring.

For CL1500 ≥ NPS 6 and CL2500 valves, install the first cage gasket (key 65) onto the seat ring.

3. Install the cage.

4. For a NotchFlo DST balanced valve, install the anti-extrusion rings (key 63) onto the valve plug (key 5). Install the seal ring (key 8) onto the valve plug (key 5). Install the ring with the open side facing the valve plug stem end of the valve plug for flow-up applications (view A of figures 10 through 16). Slide the backup ring (key 9) onto the valve plug. Secure with the retaining ring (key 10).

5. Install the valve plug into the cage.

6. Install the bonnet gasket (key 11). For CL1500 ≥ NPS 6 and CL2500 valves, install the second cage gasket (key 65) onto the cage.

7. Install the bonnet over the valve stem and onto the valve body.
