Failure to follow these instructions or to properly install and maintain this equipment could result in an explosion and/or fire causing property damage and personal injury or death.

Fisher ® equipment must be installed, operated, and maintained in accordance with federal, state, and local codes and

Fisher instructions. The installation in most states must also comply with NFPA

No. 58, and ANSI Standard K61.1.

Only personnel trained in the proper procedures, codes, standards, and regulations of the LP-gas industry should install and service this equipment.

The internal valve must be closed except during product transfer. A line break downstream of a pump may not actuate the excess flow valve. If any break occurs in the system or if the excess flow valve closes, the system should be shut down immediately.

Introduction

Scope of Manual

This manual covers instructions for the Type C403-24 and

Type C404-24 3-inch CL300 RF flanged internal valves.

Description

Type C403-24: The Type C403-24 double flanged internal valve is intended for special bobtail truck applications where the pump must be lowered to clear the truck frame or other obstacles. A shear section in the lower body permits the valve to shear off in the event of an accident, leaving the shutoff parts within the tank.

Type C404-24: The single flanged Type C404-24 internal valve is widely used on bobtail trucks with direct connected pumps. It can also be used on in-line applications.

Both type internal valves can also be used with transports and on stationary storage tanks. The valves can be operated by cable or with air.

Designed for use with Propane, Butane, or Anhydrous

Ammonia at ambient temperatures, the valves can be used on other compressed gases, but the user should check with the factory to make sure the valves are suitable for the particular service.

Specifications

The Specifications table lists specifications for

Types C403-24 and C404-24 internal valves.

DOT Internal Self-Closing Stop Valve Requirement

– U.S. Department of Transportation (DOT) regulations 49 CFR§178.337-8(a)(4) require each liquid or vapor discharge outlet on cargo tanks

(except for cargo tanks used to transport chlorine, carbon dioxide, refrigerated liquid, and certain cargo tanks certified prior to January 1, 1995) to be fitted with an internal self-closing stop valve. Fisher’s “C” series internal valves comply with the internal self-closing stop valve requirement under the

DOT regulations.

Installation

Internal Valve

Coat both sides of the spiral wound gaskets with Dow

Corning #111 silicone grease or equivalent. A 3-inch

(DN 80) ASME CL300 RF flange with a modified bore

(see Figure 2) must be installed in the tank. Special stud bolts, furnished with the valve, are assembled into this flange. The internal valve and the pump or piping flange can then be installed as shown in Figure 3.

The screen should be removed if the valve is to be used for both filling and withdrawal service or for filling alone.

Filling with screen installed is not recommended.

A hydrostatic relief valve does not need to be installed adjacent to the valve since the internal valve automatically relieves excessive line pressure into the tank.

Types C403-24 and C404-24

Keep piping from the valve outlet to the pump full size and as short as possible with a minimum of bends.

Reduction in pipe size to suit smaller pump inlets should be made as close to the pump as possible using forged reducers (swage nipples) or venturi tapers rather than bushings. This assures minimum flow resistance and efficient pump operation.

If the valve is also used to provide excess flow protection, the flow rating of the piping, fittings, pump, valves, and hose on both the inlet and outlet of the internal valve must be greater than the flow rating of the integral excess flow valve within the internal valve. If branching or other necessary restrictions are incorporated in the system which reduce the flow rating to less than that of the excess flow valve rating, the internal valve will not give excess flow protection.

Selectively Filling Manifolded Tanks

Fisher ® internal valves provide positive shutoff only in one direction, from out of the tank to downstream of the valve. The internal valves are designed to allow gas to flow into a tank when the downstream line pressure exceeds tank pressure. If you want to selectively fill one or more of the other tanks in a tank manifold system, you must place a positive shutoff valve downstream of the internal valve, otherwise, all tanks will be filled at the same time and at about the same rate.

Actuators

The remote operating control system for the valve is extremely important, and it must be installed to conform with the applicable codes. DOT MC331, for example, most generally applies for trucks.

Fisher offers both cable controls and pneumatic actuator systems to operate the Types C403 and

C404 series internal valves. It may also be possible to use cable controls from other manufacturers or to fabricate a linkage mechanism.

Any control system requires thermal protection (fuse links) at the valve, at the remote control point and, if necessary, near the hose connections. The instruction manuals for Fisher Controls actuator systems show how to install the fuse links.

Installation instructions on Fisher Types P650, P163A, and P164A cable controls, are in Form MCK-1083.

Fisher Types P613 and P623 pneumatic actuators are covered in Form MCK-2159.

The operating linkage must allow the operating lever to move from the fully closed position to within 2° of the fully open position. The linkage should not apply strong force to the lever past the fully open position or the valve could be damaged.

CAUTION

The internal valve’s closing spring is not designed to overcome drag in the control linkage in order to close the valve. Depending upon the control system used, an external spring (such as Fisher drawing number 1K4434) or positive closing linkage may be needed.

Be sure the control system is installed to prevent binding that could cause the valve to stick in the open position.

Excess Flow Operation

The internal valve contains an excess flow function, or “integral excess flow valve,” that will close when the flow exceeds the flow rating established by

Fisher. Fisher’s integral excess flow valve installed on a bobtail truck or transport can provide protection against the discharge of hazardous materials during an unloading operation of a bobtail truck or transport in the event that a pump or piping attached directly to the internal valve is sheared off before the first valve, pump, or fitting downstream of the internal valve, provided that the cargo tank pressure produces a flow rate greater than the valve’s excess flow rating.

Likewise, if the internal valve is installed on a stationary tank or in the related downstream piping system, the integral excess flow valve can provide protection against an unintentional release of hazardous materials in the event that a pump or piping attached directly to the internal valve is sheared off before the first valve, pump, or fitting downstream of the internal valve, provided that the flow of product through the internal valve reaches the rated flow specified by Fisher.

ExCESS FLOW VALVE

CLOSED and dimensions, branching, elbows, reductions in pipe diameter, or a number of other inline valves or fittings), low operating pressure as a result of ambient temperature, or a partially closed valve downstream from the integral excess flow valve, can restrict the rate of flow through the internal valve below the level necessary to actuate the integral excess flow valve. Therefore, DO NOT USE the excess flow function of the internal valve for the purpose of providing protection against the discharge of hazardous materials in the event of a rupture of hose or piping at a point in the discharge system downstream from the first valve, pump, or fitting downstream of the internal valve.

The internal valve is designed with an internal bleed feature for equalization of pressure. After the integral excess flow valve closes, the leakage through the bleed must be controlled or a hazard can be created. For this reason the operator must be familiar with the closure controls for the internal valves and must close the internal valve immediately after the integral excess flow valve closes.

Failure to follow this warning could result in serious personal injury or property damage from a fire or explosion.

DOT Passive Shutdown Equipment Requirement

– DOT regulations 49 CFR§173.315(n)(2) require certain cargo tanks transporting propane, anhydrous ammonia and other liquiefied compressed gases to be equipped with passive emergency discharge control equipment that will automatically shut off the flow of product without human intervention within 20 seconds of an unintentional release caused by complete separation of a delivery hose. The design for each passive shutdown system must be certified by a Design Certifying Engineer

(DCE) and all components of the discharge system that are integral to the design must be included in the DCE certification. The DCE certification must consider any specifications of the original component manufacturer.

In the case of downstream ruptures in hose or piping, a variety of operating conditions routinely encountered during an unloading operation restrict the rate of flow through the integral excess flow valve and make such a valve unsuitable to serve as the means of passive shutdown required under 49 CFR§173.315(n)(2).

Such variables include restrictions incorporated in the discharge system (due to pumps, pipe and hose length and dimensions, branching, elbows, reductions in pipe diameter, or a number of other in-line valves or fittings), low operating pressure as a result of ambient temperature, or a partially closed valve downstream from the excess flow valve. Due to the variety of conditions, in the case of a hose separation, that can restrict the rate of flow below the level necessary to activate the excess flow valves, the integral excess flow function of Fisher ® ’s “C” Series internal valves or “F” Series excess flow valves cannot be used to

4

Types C403-24 and C404-24 satisfy the passive shutdown equipment requirement under/in 49 CFR§173.315(n)(2). Also, a Design

Certifying Engineer cannot include the integral excess flow valve of a Fisher ® “C” Series internal valve or

“F” Series excess flow valve as a component of the discharge system in any DCE certification under 49

CFR§173.315(n)(2).

DO NOT USE the excess flow function incorporated into Fisher “C” Series internal valves or “F” Series excess flow valves to satisfy the passive shutdown equipment requirement in

49 CFR§173.315(n)(2). DO NOT include the excess flow function incorporated into Fisher “C” Series internal valves or

“F” Series excess flow valves in a DCE certification under 49 CFR§173.315(n)(2).

The cargo tank manufacturer must install some other equipment that satisfies the requirement for passive shutdown capability under 49 CFR§173.315(n)(2).

Failure to follow this warning could result in serious personal injury or property damage from a fire or explosion in the event of an unintentional release of product during an unloading operation.

Operation

Since the Types C404-24 and C403-24 are most often used on bobtail trucks, the following procedure applies to that type of application. Follow these points:

1. Types C400s on bobtails and transports should

never be open when the truck is in motion. If

the control system is not interlocked to prevent

this, the operator is responsible to see that the

valves are closed.

2. Always open the internal valve before opening any

other valves in the line or starting the pump.

3. Move the lever to the half-open position

(Figure 4, View 2) to equalize pressure. When

the main poppet clicks open, move the operating

lever fully open.

4. Open other line valves slowly to avoid sudden

surges which could slug the excess flow valve shut.

5.

If the excess flow valve does close, stop the

pump and close the nearest downstream valve.

Move the internal valve’s operating lever back to

the rapid equalizing position and wait for the valve

to click open. Then move the operating lever fully

open and slowly open the downstream valve.

6. All valves should be completely open when

pumping. (Throttling type valves could prevent

the excess flow valve from closing when required.)

7. The operator must always be aware of where the

remote closure controls are located and know

how to operate the controls if an emergency

requires valve closure. When pumping is finished,

make a habit of closing the internal valve from the

remote closure point, thus checking to see that the

control actually is capable of closing the valve.

8. The valve should be open when backfilling through

the valve to fill the tank.

Troubleshooting

Internal Valve Will Not Open – This could be due to leakage downstream, engaging the pump too soon or from excessive wear in the internal valve. If excessive volume is in the downstream system, a longer time is required to equalize the pressures (tank and downstream) before the pump can be engaged.

To determine if the valve pilot seat is opening, install a gauge downstream of the valve, operate the valve actuator; if pressure does not build up to the tank pressure, the valve pilot seat is not open. This test should be done with pump off. If the pilot is not opening, it may be plugged with dirt or some internal part may be broken. If by operating the lever manually it can be rotated past the fully open position, there is something wrong internally and the valve must be disassembled.

Premature Valve Closure – This can be caused from engaging the pump too soon, by an underrated excess flow valve spring, or by an improperly connected internal valve operating lever which does not fully open the valve. The trouble could also be from a valve that has its inlet port obstructed or from sudden line surges.

In order to check the valve opening travel, operate the lever manually to the full travel, wait until valve opens

(usually about 15 seconds), then engage the pump.

If the excess flow closes, the points mentioned above should be investigated.

Types C403-24 and C404-24

Internal Valve Will Not Close – The stub shaft could be binding or the stem could be bent in the valve. Before disassembling the valve, check the actuator mechanism to see that it operates freely by disconnecting it from the valve lever and cycling it several times. Also, operate the valve lever manually. If it sticks in the open position, the packing and bushings should be replaced. This should free the operating mechanism if the valve has not been damaged internally. Refer to the “Maintenance” section.

Low Flow Capacity – This could be caused by too small an internal valve, too small or long downstream piping, plugged screens, some other restriction in the downstream system, or by the bypass valve sticking in the open position. The bypass valve could also be set too low and be opening prematurely.

Principle of Operation

Refer to the schematic drawing, Figure 4. In View 1, the valve is held closed by both tank pressure and the valve’s closing spring. There is no leakage past the resilient seats in the poppet to the valve outlet.

The valve is opened by moving the operating lever to approximately midpoint in its 70° travel (View 2). This allows the cam to place the rapid equalization portion of the valve stem in the pilot opening, permitting a larger amount of product to bleed downstream than if the operating lever were moved to the full open position.

When tank and downstream pressure are nearly equal after a few seconds, the excess flow spring pushes open the main poppet (View 3) and the operating lever can be moved to the full open position.

If tank pressure is greater than the valve’s outlet pressure, the main poppet will remain in the closed position. If valve outlet piping is closed off by other valves, however, product bleeding through the pilot will increase until it nearly equals tank pressure and the main poppet opens.

Note

The main poppet will not open if valve outlet piping is not closed off so that the outlet pressure can approach tank pressure.

Once the main poppet opens, a flow greater than the valve’s excess flow spring rating or a sufficient surge in flow forces the main poppet closed against the excess flow spring (View 4). The pilot valve allows a small amount of product to bleed, but much less than

View 2 where the rapid equalization portion of the stem is placed in the pilot opening. When the operating lever is moved to the closed position, the valve closes completely and seals tightly (View 1).

Maintenance

CAUTION

Do not use these internal valves if they leak, fail to work properly or have been damaged or have missing parts. Prompt repairs should be made by a properly trained serviceman. Continued use without repair can create a hazardous or injurious situation.

A simple preventative maintenance program for the valve and its controls will eliminate a lot of potential problems.

Fisher ® recommends these steps be conducted once a month. Also refer to the Department of

Transportation (DOT) CFR 49 Sections 180.416 and 180 Appendix A and B which specific monthly maintenance and inspection tests for cargo tank service internal valves and their actuation controls.

1. Inspect the operating lever to see that it

operates freely and that there is no

leakage around the retainer nut. If there is

sticking or leakage, replace the packing and

bushings. Refer to parts list.

2. Check for tight closure of the seat disks. Any

detected leakage, which is normally caused by

disk wear or dirt, scale or debris embedded in

the disk, requires that the internal valve be

removed from service and repaired. Repair most

often requires the replacement of valve disks.

To check for leakage:

a. Close the internal valve and exhaust downstream

pressure. Close the first valve downstream from

the internal valve, and note any pressure buildup,

using a pressure gauge, between the closed valve

and the internal valve. If piping is cold allow it to

warm to ambient temperature.

Types C403-24 and C404-24

b. Refer to CFR 49 Section 180 Appendix B for Meter

Creep Test Methods.

3. All operating controls should be inspected,

cleaned and oiled. The controls should be

checked to see that they fully open—but not over-

travel the internal valve operating lever and

operate freely to close the valve.

4. Standard construction internal valves must be

removed if the container is to be steam cleaned.

Heat can damage the valve’s seats and seals.

5. Standard construction internal valves are not

designed for water service. Immediately after

a container is hydrostatically tested, remove all

water and allow the container to thoroughly dry out.

Disassembly

!

WARNINg

Tank pressure must be released before removing the valve from the container. Failure to do so could result in personal injury.

Numbers in parenthesis refer to key numbers in

Figures 5 and 6.

To Replace Packing (keys 15F, 15g, and

15H), bushings (keys 15B and 15K) or cam (key 15P):

1. With the valve in the tank, close the operating

lever (key 18, not shown) and remove the

downstream pressure in the system.

2. For Type C404-24: Unscrew the capscrew

(key 15R) with a 7/16-inch (11,1 mm) wrench.

For Type C403-24: Remove the pipe plug

(key 22). Using a 3/16-inch (4,76 mm) Allen

wrench, unscrew the cap screw (key 15R).

Remove the washer (key 15S) and the cam

(key 15P).

3. After removing the operating lever (key 18), the

packing can be reached by unscrewing the bonnet

nut (key 15M) and removing the stub shaft

(key 15J). Inspect and replace if necessary, the

packings (keys 15F, 15G, and 15H), bushings

(keys 15B and 15K). Lubricate the packings with

Magna Lub G and the bonnet nut (key 15M) with

Never Seize.

4. Reassemble in the reverse order.

Replace the cap screw (key 15R) with 30 to

35 inch-pounds (3 to 4 N•m) torque.

5. Make sure the operating lever (key 18) can move

freely after the new parts are installed. Conduct

a leak test under pressure with a leak

detection solution.

To Replace Seat Disks (keys 7 and 11) or the Excess Flow Spring (key 3).

1. Remove the valve from the tank and remove the

screen from the valve.

2. Remove the Guide Bracket (key 47) for

Type C403-24 or the Valve Cage (key 37) for the

Type C404-24.

3. Unscrew hex nut (key 13).

4. Remove both disk holders (keys 6 and 12)

from the stem (key 2).

5. Unscrew the 3 screws (key 9) holding the disk

retainer (key 8) to replace the main disk seat

(key 7).

6. Examine both seat disks (keys 7 and 11) and

replace if necessary.

7. If the excess flow spring (key 3) is changed,

restamp the nameplate with the new excess flow

rating and type number.

8. Always replace the sealing washer (key 23).

9. Reassemble in the reverse order using

15 to 20 foot-pounds (20 to 27 N•m) torque to

install the disk retainer (key 8). Apply Loctite 242 or

equivalent on the stem threads before installing the

hex nut (key 13). Tighten hex nut (key 13) to

80 inch-pounds (9 N•m) torque.

Pressure test the repaired valve for seat leakage, opening and closing, and excess flow operation as described in earlier portions of this manual.
