Installation & Maintenance Instructions for the

Mark ED & ET Series 8-Inch Globe Style Control

Valve

Warning: Jordan Valve Control Valves must only be used, installed and repaired in accordance with these Installa­tion & Maintenance Instructions. Observe all applicable public and company codes and regulations. In the event
of leakage or other malfunction, call a qualified service person; continued operation may cause system failure or
a general hazard. Before servicing any valve, disconnect, shut off, or bypass all pressurized fluid. Before disassem­bling a valve, be sure to release all spring tension.

IntroductIon

Contained in this manual are installation instructions,
maintenance and parts information for the Mark ED and
ET Series 8-inch Globe Style Control Valves. Refer to the
appropriate manuals for instructions for the accompany­ing actuator, positioner and additional accessories.

Only trained or experienced personnel should carry out
the operation and installation of all pressure equipment.
If you have any questions regarding the equipment, con­tact your Jordan Valve Controls representative.

MaIntenance

Before beginning any maintenance, it is important
to isolate the control valve and release all pressure
contained in the valve body and the actuator.
Disconnect any operating lines providing air
pressure, control signals or electrical power to the
actuator.

Note: Caution must be used in the disassembly.
The seating surfaces and surface nish of the
cage; seat ring, stem, and plug are critical for
proper sealing. Nicks and scratches will affect
the ability to seal the valve in the future.

InstallatIon

The Mark ED and ET Series 8” valve should not be
installed in systems that exceed the ANSI specified tem­perature and pressure ratings.

Inspect the valves for shipping damage and foreign
debris when uncrating.

1. Ensure the pipe is free of welding slag, chips,
and other debris by cleaning out the lines
before installation.

2. Install approved gaskets between the valve
body and the pipeline flanges.

3. Jordan Valve recommends a standard three-
valve maintenance bypass be installed. This
allows isolation of the valve body without shut
ting down the pipeline system.

4. Install the valve so that the flow direction arrow
on the body coincides with the actual process
flow through the valve.

5. Although the valve can be installed in any po-
sition, the typical installation has the actuator
vertical above the valve body. Support
for the actuator will be necessary if there is
vibration in the line or if the valve body is
positioned 45 degrees or more below vertical.

Disassembly

1. Disconnect and remove the actuator from
the body.

2. Remove the nuts or cap screws from the
bonnet flange.

3. Thread one of the actuator stem locknuts
onto the stem and continue threading it
down to the bottom of the thread run out.

4. Remove the bonnet by lifting it straight up
with a hoist. Attach the hoist by either a
double cable hoisting sling under
the bonnet or by the lifting rings attached
to the packing flange stud bolts or
on the 5” yoke bosses to
two yoke stud bolts 180° apart.

5. Caution must be used when lifting the
bonnet to ensure that it clears the
body and stud bolts completely. Any
damage to the seating surface
will compromise future sealing ability

6. To prevent damage to the seating surface,
place the bonnet-valve plug assembly on
a wooden or cushioned surface.

Replacing the Plug Stem or Load Ring

1. Unscrew the locknuts from the stem.

2. Loosen the packing flange nuts.

3. Lean the bonnet over.

4. Draw the plug and stem out of the bonnet.

5. If valve plug is damaged it will be necessary
to replace both the valve plug and stem. If the
stem is damaged, a new valve stem can
be inserted in the original valve plug.

Replacing the Stem

1. Remove the old groove pin

2. Remove the old stem, and replace with new
stem.

3. Tighten the new stem until the thread bottoms
out against the plug.

4. Drill through the stem using the hole in the valve
plug as guide. Remove any chips or burrs and
drive in a new groove pin to lock the assembly.
Refer to Table 1 for groove pin drill sizes.

Assembly

1. Ensure all gasket surfaces are clean.

2. Replace the valve plug piston ring or seal
ring with a new ring.

3. Assembly for design:

3.1. Mark "ED” Design Bodies:
For valve bodies using a carbon filled
TFE piston ring, at the split, slightly
spread the ring and install it over
the stem and into 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 i.e.) edge of a table. Ensure
the broken ends are
re-matched when the
piston ring is installed in the piston
ring groove.

Figure 1: Groove Pin Pilot Holes

3.2. Mark "ET” Design Bodies:
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 procedure may make the
seal ring seem loose
in the groove, however it will contract
to its original size after installation of
the cage.

Assembly Continued,

4. Replace the seat ring gasket, and install the seat
ring. If using a composition seat (TFE),
assemble it by placing the TFE disc onto
the disc retainer and then sliding this assembly
over the disc seat.

5. Place the cage onto the seat ring. Any rotational
orientation of the cage with respect to the valve
body is acceptable.

6. To ensure a good seal, clean all sealing surfaces
and examine surfaces for nicks and scratches.
Place the bonnet gasket in position.

7. Slide the valve plug assembly in the cage, and
then position the load ring on top of the cage.

8. Place the bonnet on the body ensuring that the
pipe plug (or lubricator) is on the downstream
side of the body.

9. Using good bolting practices, bolt the bonnet
to the body. Lubricate the studs and nuts us
ing good quality lubrication.
Tighten the bolts alternately.
Correct tightening of the bonnet bolts
accomplishes two objectives.

Packing Lubrication

The use of semi-metallic packing requires the use of a
lubricator or lubricator/isolating valve (Figure 2). The
lubricator or lubricator/isolating valve is mounted in
place of pipe plug (Figure 2, Key 15). For standard
service up to 450ºF, use Dow Corning lubricant or
equivalent. Do not lubricate packing used in oxygen
service.

Lubricator -To add lubricant to the packing box, turn
the cap screw in a clockwise direction.

Lubricator/Isolating Valve - Open the isolating valve,
turn the cap screw in a clockwise direction, and then
close the isolating valve.

9.1. To compress the bonnet gasket to form
a seal with the body joint.

9.2. Bolt loads are transmitted to the cage
through the load ring, which creates a
sealing load for the seat ring gasket.

10. Mount the actuator to the bonnet and make up
the stem connection. Refer to “Making Up the
Stem Connection” for proper procedure.

Replacing TFE V-Ring Packing

1. After the stem and valve plug have been
detached from the bonnet, the following parts
can be removed:

1.1. Packing nuts

1.2. Packing flange

1.3. Wiper ring

1.4. Packing follower

2. The old packing can be removed by one of two
methods:

2.1. Remove the packing by pushing it out
using a rod inserted through bottom of
the bonnet.

2.2. Use a packing hook to remove the
packing. Note: To avoid damaging the
packing box walls use caution.

3. Clean the packing box bore, and all metal
parts. Complete all required maintenance.

4. Slide the valve plug into the cage already in
the valve body, install the load ring on the
cage, and use a new bonnet gasket. Mount
the bonnet to the valve body.

5. Complete the installation of the packing as il­ lustrated in Figure 3.

Note: Extra caution should be taken not to damage
the packing during the installation process.

6. Replace the packing flange (Key 27); tighten
the packing flange nuts (Key 29) until shoulder
of packing follower (Key 30) is approximately
5/8” from the top of the bonnet. If leakage is
detected around the packing follower, tighten
the packing flange nuts until leakage stops.

7. For graphite packing, tighten the packing
flange nuts to the maximum torque value in
Table 3. Then back off the nuts and retighten
them to the minimum torque value in Table 3.

8. For other Packing Types, in small equal incre­ ments tighten the flange nuts until one of the
nuts reach the minimum torque shown in Table

3. Then tighten the other nut until the packing
flange is level.

9. Mount the actuator and set the stem connector
to the required travel. Refer to “Making Up the
Stem Connection” procedure.

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 surfaces 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 bottom of 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
bonnet, clean the seating surfaces, reassemble, and
then test for shutoff. If leakage is still excessive, repeat
lapping procedure.

Making Up the Stem Connection

Direct-Acting Actuators

1. Move the valve plug to the closed position.

2. Thread the actuator stem locknuts to the bottom
of the plug stem threads. Position the
travel indicator disc, cupped edge downward,
over the stem. Apply enough spring force to the
actuator stem to ensure the actuator is in the
“full up” position.

3. Move the actuator stem to the full downward po-
sition by applying full loading pressure
to the diaphragm case. Measure the distance
between the lower end of the actuator stem and
the travel indicator disc on the stem locknuts.

4. Slowly decrease the load on the actuator, allow
ing the stem to rise up approximately by 1/8”.
Using the two-piece stem connector and
cap screws, secure the actuator stem and valve
plug stem together.

5. Place the travel indicator disc against the bot-
tom of the stem connector. Secure the disc in
place with the upper locknut. Adjust the
travel indicator scale so it reads “closed.”

Double Packing

All Yoke sizes

6. Relieve the diaphragm loading pressure
and check for sufficient travel. i.e.) Move
ment of valve plug to the fully “Open”
position. Tighten the lower stem locknut
against the upper locknut. The connection
is now complete.

To increase desired length of travel:
a. Loosen both stem locknuts away
from the stem connector by ap-
proximately 1/4” and then tighten
them together.
b. This adjustment will allow a wrench
to be used on the locknuts to
screw the valve plug stem to the
desired position.
c. Caution: ensure that the valve plug
is not seated while being rotated.
Do not exceed the 1/8” adjustment
made in Step 4.
d. Retighten the stem connector and
locknuts after adjustment.
e. Reposition the travel indicator
scale to reflect the change.

Making Up the Stem Connection Cont.,

Reverse-Acting Actuators

1. Close the valve plug ensuring the valve plug is on

the seat.

2. Supply enough spring force to the actuator stem to

ensure the actuator is in full “Down” position. In­crease the loading pressure to the diaphragm case
to allow the actuator stem to rise sufficiently so the
locknuts can be screwed onto the valve plug stem.
Thread the locknuts down on the valve plug stem
as far as possible. Set the travel indicator on the
locknuts, “cupped” edge downward.

3. Slowly release the pressure in the diaphragm case,

allowing the actuator to return to the full down posi­tion. Measure the distance between the lower end
of the actuator stem and the travel indicator disc.

4. Increase the load on the actuator, causing the stem

to rise up by approximately 1/8”. Using the two­piece stem connector and cap screws, secure the
actuator stem and valve plug stem together.

5. Move the travel indicator disc against the bottom of

the stem connector.

6. Secure the disc with the upper locknut. Change the

travel indicator scale so that it reads closed.

7. Open the valve plug by increasing the diaphragm

loading pressure. Secure the lower stem locknut
against the upper locknut. The connection is now
complete.

8. To increase travel see “To increase desired length of

travel” instructions.
