Applications and Features
The CVS Series E is a single port, globe-style body
with composition or metal seats and a balanced
push-down-to-close valve action plug.
There are two styles of valve available, providing
excellent pressure and flow control on steam, gasses
and various liquid applications:
1. Design ED is intended for general control
applications over a wide variety of temperatures
and pressure drops. This design has an upper
piston ring seal and metal-to-metal seating.
2. Design ET is intended for applications requiring
low leakage rates with composition seating
(TFE) for tight shutoff requirements or metal-tometal seating for higher temperature capabilities.
The valve plug has a two-piece upper seal.
Figure 1: CVS Series E Valve
For standard cages the flow direction is flow-down.
The following flow characteristics are available:
linear, quick opening and equal percent.
The end connections are ANSI Class 150, 300 and
600 Raised Face, or Ring Type Joint flanges as per
ASME B16.34-latest edition.
CVS Series E Globe Valve are available in the
following body materials - LCC, WCB, WCC, WC9,
C5, Monel, and CF8M SST. Additional materials
may be available upon request.
Trim material is available in 316SST, 416SST,
17-4PH, Alloy6-Co.Cr-A, Cobalt and

Installation
1. Before installing a CVS Series E valve carefully
inspect for damage that may have occurred in
shipment.
2. Remove all welding slag, pipe scale and any
other foreign matter by cleaning out the lines
before installation.
3. Install the valve so that the flow direction arrow
on the body coincides with the actual process
flow through the valve.
4. Use accepted piping practices when installing
the valve. Use a suitable gasket between
pipeline flanges and valve body.
5. Although the control valve can be installed in any
position, the typical installation has the actuator
vertical above the body.
6. Installing a conventional 3-valve bypass around
the body will allow for continuous operation
during maintenance and inspection.
7. CVS Series E valve bodies are rated at 150, 300
and 600 lb. ANSI. Be sure not to install the valve
in any system where working pressures are
greater than those specified in the standards.

Maintenance
Warning:
To avoid damage to the process system or personal
injury, isolate the valve from the system and relieve
any pressure contained within prior to disassembly.
Disconnect any operating lines providing air
pressure, control signals or electrical power to the
actuator.
Disassembly
Except where indicated, refer to Figure 2 for part
descriptions used in the following procedure.
1. With the actuator disconnected and removed
from the body, remove the hex nuts, (key 15,
figure 9).
2. Remove the bonnet with the valve plug and
stem.
3. Loosen the packing flange nuts (key 5, figure 8)
and remove the valve plug and stem from the
bonnet. If the valve stem needs replacement,
punch out the groove pin and unscrew the stem.
If the valve plug needs replacement, a new valve
plug and stem assembly is required.
Warning: Do not use an old stem with a new
valve plug. Using an old stem requires drilling a
new hole for the groove pin and as a result, the
integrity of the stem is weakened.
4. If desired you may disassemble the internal parts
of the bonnet. To replace the Packing, see
instructions titled “Packing Replacement” in this
manual.
Warning: The portion of the cage which is
exposed provides a guiding surface. Ensure that
this surface is not damaged during disassembly
or maintenance. If the cage is seized in the body,
use a rubber mallet to strike the exposed portion
at varying points around its circumference.
5. Remove the cage and gaskets from the valve
body. With restricted trim, (figure 11) remove the
seat ring adaptor (key 5) and the cage adaptor
(key 4).
6. Remove the seat ring and its gasket. With
composition seats, remove the disc retainer, disc
seat and TFE disc.
Reassembly
Except where indicated refer to Figure 2 for part
descriptions used in the following procedure.
1. Clean all gasket-seating surfaces. Use new
gaskets only for reassembly.
2. With restricted trim (figure 11) install the seat
ring adaptor gasket (key 13) and the adaptor
(key 5).
3. Replace the seat ring gasket (key 12) and install
the seat ring (key 8). If using a composition seat,
assemble it by placing the TFE disc (key 20) into
the disc retainer (key 18), then sliding this
assembly over the disc seat (key 19).
Figure 3: Equal Percentage Cage
4. Place the cage (key 3) onto the seat ring (key 9).
Any rotational orientation of the cage with
respect to the valve body is acceptable.
5. With full-sized trim, install cage gasket (key 10),
spiral wound gasket (key 11) and bonnet gasket
(key 9) onto the cage shoulder.
6. With restricted trim, install the cage gasket (key
10), spiral wound gasket (key 11) and an
additional cage gasket (key 10) onto the cage
shoulder. Install the cage adaptor and place the
bonnet gasket onto the adaptor.
7. If installing a new stem in the valve plug, screw
the new stem into the valve plug. Refer to Table
2 for appropriate torque values and drill sizes.
Drill through the stem, using the hole in the valve
plug as a guide. Remove any chips or burrs and
drive in a new groove pin to lock the assembly.
8. If the seal ring appears damaged, remove and
replace with a new one. Be careful not to scratch
the ring groove surfaces. Damage to the ring
groove surface may prevent the new ring from
sealing properly. The seal ring must either be
pried or cut from the groove and therefore
cannot be reused.
If possible, lapping of metal seats should be
done before seal ring installation. Refer to the
“Lapping Metal Seats” procedure in this manual.
8a For valve bodies using a carbon-filled TFE piston
ring, locate the split and slightly spread the ring.
Install the ring over the stem and onto the piston
ring groove on the valve plug. Graphite piston
rings are supplied as a complete ring and must
be broken into two sections. The piston ring can
be broken in half by scoring, and then breaking
over a hard surface such as the edge of a table.
Ensure the broken ends are re-matched when
the piston ring is installed in the piston ring
groove.
3
Reassembly cont’d
8b Apply a lubricant to both back-up ring and seal
rings. Install the back-up ring over the stem and
into the piston ring groove. Place the seal ring
over the top edge of the valve plug, so that it
slips into the groove on one side of the valve
plug.
Cautiously stretch the seal ring to work it over
the top edge of the valve plug. Avoid jerking
sharply on the seal, as the TFE in the seal ring
needs time to cold flow during the stretching
procedure. This stretching may make the seal
ring seem loose in the groove; however it will
contract to its original size after installation of the
cage.
9. When placing the valve plug into the cage,
ensure that the seal ring is evenly set in the
entrance bevel at the top of the cage to avoid
ring damage.
10. Mount bonnet to the body.
11. Tighten the bonnet to body bolts. Refer to Table
3 for recommended torques.
Always adhere to accepted bolting practices and
lubricate bolts. Correct tightening of the bonnet bolts
accomplishes the following:
a) The spiral wound gasket will compress
enough to load and seal the seat ring
gasket.
b) The outer portion of the top gasket will
compress so that the bonnet to body
connection forms a seal.
Note: Bolt up characteristics for spiral wound
gaskets are such that the tightening of one bolt may
loosen another. This will occur with the tightening of
all the bolts until the bonnet to body seal is made.
Several trials on each bolt are required until, at the
given torque, the nut does not turn.
12. Mount the actuator to the bonnet and make up
the stem connection. Refer to “Making up Stem
Connection” instructions in this manual.

Packing Maintenance
TFE V-Ring Packing
Except where indicated, refer to Figure 8 for part
descriptions used in the following procedure.
1. For spring loaded single TFE V-ring packing, the
spring (key 8) maintains the sealing force on the
packing. If leakage is detected around the
packing follower (key 13), tighten the packing
flange nuts (key 5) until the leakage stops. If the
shoulder of the packing box is touching the
bonnet and leakage cannot be controlled in this
manner, see “Packing Replacement”.
Packing Replacement
1. Once the actuator and bonnet have been
separated from the body (refer to Steps 1-2 of
Disassembly procedure), remove the following
from the bonnet:
a. Packing flange nuts (key 5)
b. Packing flange (key 3)
c. Felt wiper (key 12)
d. Packing follower (key 13)

2. Clean the packing box bore, spring (key 8),
washer (key 10), and the packing box ring (key
11).
3. Install the valve plug assembly and mount the
bonnet to the body using new gaskets. Use the
sequence shown in Figure 4 to install new
packing and associated parts. Be sure not to
damage the packing during installation. Replace
the packing flange (key 3), tighten the packing
flange nuts (key 5) until the shoulder of the
packing follower (key 13) is approximately 5/8”
from the top of the bonnet. If leakage is detected
around the packing follower, tighten the packing
flange nuts until the leakage stops.
4. For graphite packing, tighten the packing flange
nuts to the maximum torque value in Table 4.
Then back off the nuts and retighten them to the
minimum torque value in Table 4.
5. For other Packing Types, in small equal
increments, tighten the flange nuts until one of
the nuts reach the minimum torque shown in
Table 4. Then, tighten the other nut until the
packing flange is level.
6. Mount the actuator and set the stem connector
to the required travel. Refer to “Making Up Stem
Connection” procedure.
Lubricator/Isolating Valve: Open the isolating
valve, turn the cap screw in a clockwise direction,
then close the isolating valve.
Lapping Metal Seats
In any valve body, a certain amount of leakage
should be expected with metal-to-metal seating.
However, if the leakage becomes excessive, lapping
can enhance the condition of the seating surfaces of
the valve plug and seat ring. Deep nicks in the
seating surface should be removed by machining
rather than lapping. There are many lapping
compounds available commercially. Be sure to use
one of high quality. Apply lapping compound to the
bottom of the plug.
In order to position the cage and seat ring properly
and to help align the valve plug with the seat ring,
bolt the bonnet to the body with gaskets (the old
gaskets can be used) in place during the lapping
procedure. A simple handle can be made from a
piece of metal secured to the valve stem with nuts.
Rotate the handle in opposite directions to lap the
seating surfaces. Once lapping is complete,
disconnect the bonnet, clean the seating surfaces,
reassemble and then test for shutoff. If leakage is
still excessive, repeat the lapping procedure.
Packing Lubrication
The use of semi-metallic packing requires the use of
a lubricator or lubricator/isolating valve (figure 5).
The lubricator or lubricator/isolating valve is mounted
in place of a pipe plug (key 14, figure 7, 8). For
o
standard service up to 450 F, use Dow Corning
lubricant or equivalent.
Lubricator: To add lubricant to the packing box, turn
the cap screw in a clockwise direction.

Making Up Stem Connection
Direct Acting Actuator
Refer to Figure 6 for part descriptions used in the
following procedure.
1. Move the valve plug to the closed position.
2. Thread stem locknuts onto the stem and set the
travel indicator disc on these nuts. The cupped
portion of the indicator disc should face
downward.
3. Move the valve plug stem up the required travel
and attach the stem connector. Make sure there
is full engagement of the actuator stem threads.
Place the two cap screws in the stem connector
and tighten only slightly at this time. Position the
travel indicator disc against the bottom of the
stem connector by tightening the stem lock nuts
slightly.
4. The travel indicator should indicate the valve to
be wide open with no pressure on the
diaphragm. If it does not, loosen the screws that
hold the travel indicator scale and move the
scale to the position required.
5. Apply varying pressures to the diaphragm case
and observe the valve travel. Make certain that
the valve plug seats on the seat ring.
Note: If the travel is not correct on units with plain or
extension bonnets, the travel can be corrected by
screwing the valve plug stem either into or out of the
stem connector. Always use a wrench on the lock
nuts to turn the stem. Do not use pliers or a pipe
wrench directly on the stem itself. Make sure not to
turn the valve plug while it is on the seat.
Reverse Acting Actuator
Refer to Figure 6 for part descriptions used in the
following procedure.
1. Move the valve plug to closed position.
2. Thread stem locknuts onto stem then set the
travel indicator disc on these nuts. The cupped
portion of the indicator disc should face
downward.
3. Move the valve plug stem up the required travel
and attach the stem connector. Make sure there
is full engagement of the actuator stem threads.
Place the two cap screws in the stem connector
and tighten only slightly at this time. Position the
travel indicator disc against the bottom of the
stem connector by tightening the stem lock nuts
slightly.
4. The travel indicator should indicate the valve to
be wide open with non pressure on the
diaphragm. If it does not, loosen the screws that
hold the travel indicator scale and move the
scale to the required position.
5. Apply varying pressures to the diaphragm case
and observe the valve travel. Make certain that
the valve plug seats on the seat ring.
Note: If the travel is not correct on units with plain or
extension bonnets, the travel can be corrected by
screwing the valve plug stem either into or out of the
stem connector. Always use a wrench on the lock
nuts to turn the stem. Do not use pliers or a pipe
wrench directly on the stem itself. Make sure not to
turn the valve plug while it is on the seat.
