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 H-900,
H-1500 and H-2500 Series Valve Bodies. 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 representative. A
serial number identifies each Mark H Series valve and
is stamped on the valve body. Please reference this
number when communicating with your Jordan Valve
representative.

Mark H-900, H-1500 and H-2500 Series Globe
Style Control Valves
3. For continuous service applications, Jordan
Valve recommends a standard three-valve
maintenance bypass be installed. This
allows isolation of the valve body without
shutting down the pipeline system.
4. The valve should be positioned on the
line so the flow direction indicator corresponds to the direction of flow in the
pipeline.
Note: The effectiveness of the pressure-energized
seal will be compromised if return ow exists
where the downstream pressure exceeds upstream pressure. The result could be leakage or
damage to the seal.
InstallatIon
These valves 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.
Be sure to use proper hoists with chains or slings
when uncrating and handling these valves. Refer to
Table 1 in the data sheet for valve body weights.
1. Ensure the pipe is free from welding slag,
chips and other debris by blowing out the line
prior to installation.
2. Install approved gaskets between the valve
body and the pipeline flanges. For butt weld
ends on the Mark ET Series trim configuration,
remove gaskets and seal rings prior to welding
the body into the pipeline.
5. The valve body should be positioned with
the actuator vertically above it. It is possible to position the valve with an
orientation below vertical with support
supplied for the actuator. Support for the
actuator is required if there is excessive
vibration in the line, or if the valve body is
positioned more than 45 degrees off
vertical.

MaIntenance
Internal valve components are subject to normal deterioration and must be inspected and replaced as required.
The necessity of inspections and replacement of parts
will depend on the severity of service conditions. Inspections and maintenance must be carried out on a regular
basis.
Before beginning any maintenance, it is important to isolate the control valve and release all pressure contained
in the valve body and the actuator.
Packing Replacement
These instructions refer to the replacement of single or
double TFE V-Ring, Garlock and Grafoil packing. Key
numbers refer to Figures 1, 2 and 3.
1. Release all loading pressure in the actuator and
remove control lines.
2. Remove the cap screws from the stem
connecter and detach the halves of the stem
connecter.

Bonnet Parts
3. Unscrew the yoke locknut (Figure 3, Key 28) and
separate the actuator from the bonnet
(Figure 3, Key 17).
4. Remove the hex nuts (Figure 1, Key 8) and lift
the bonnet (Figure 3, Key 17) and valve plug
and stem assembly from the valve body
(Figure 1, Key 7). Set those components on a
clean surface and protect the gasket sealing
serrations in the bottom of the bonnet. These
serrations are essential for a tight seal between
the body and bonnet during reassembly.
5. Remove the bonnet gasket (Figure 1 and 2, Key 4).
6. Loosen the packing flange nuts (Figure 3, Key
20) so the packing becomes loose around the
stem.
7. Remove the hex nuts from the valve plug stem
(Figure 1, Key 3) and pull the valve plug and stem assembly out of the bonnet. Place this assembly on a protective surface.
8. Remove the hex nuts (Figure 3, Key 20), the packing flange (Figure 3, Key 18), the packing
follower (Figure 3, Key 26) and the felt wiper (Figure 3, Key 25).

9. Use a packing hook to remove the packing
parts, or push them toward the top of the bon net using a small rod. Be careful not to scratch
the wall of the packing box.
10. Clean the metal packing parts and the pack ing box, and check the valve stem and pack ing box surfaces for nicks or scratches.
Remove any light scratches with sanding. If
damage exists that cannot be sanded out, the
valve plug stem and bonnet must be replaced.
11. Install a new bonnet gasket (Figures 2 and 3,
Key 4) onto the cage (Figures 2 and 3, Key
12).
Note: The valve plug assembly of the ED and ET t
inside the cage with tight tolerances. When installing the valve plug assembly be sure not to damage
the piston rings or the seal ring (Figures 2 and 3,
Keys 6, 6a, 6b).
When the bonnet is being mounted, the threads of
the valve plug stem will slide through the packing
box. If the packing has been installed, carefully attach the bonnet to avoid cutting the packing on the
stem threads.
14. Refer to Figure 3 and arrange the packing
parts as outlined. Slide the new packing care
fully over the valve plug stem, and ensure that
the packing parts are not damaged by the
threads of the valve plug stem.
15. Reinstall the packing flange and hex nuts
(Keys 18 and 20). Tighten the hex nuts until
the shoulder of the packing follower (Key 26) is
snug against the packing box.
16. Mount the actuator onto the valve body assem bly and reconnect the actuator and valve stem
referring to procedures in the appropriate ac tuator manual.
12. Insert the valve plug assembly in the cage,
mounting the bonnet onto the body. Ensure
that the leak-off piping (or pipe plug, Figure 3,
Key 27) is facing downstream.
13. Apply lubricant to the body stud bolts (Figures
1 and 2, Key 9) and the hex nuts (Figures 1
and 2, Key 8). Thread the nuts onto the body
stud bolts using good bolting practices. Refer
to Table 1 for proper bolt torques and tighten
the nuts in a criss-cross pattern (See Figure 4).
When the control valve assembly reaches
operating temperature, repeat the procedure.
Proper tightening of the bonnet nuts ensures
a positive sealing of the cage seals and the
spring seal.
Note: Repeating the bolting pattern may be necessary since tightening one nut may loosen an adjacent nut. The body-to-bonnet seal will be complete
when none of the nuts will turn at the recommended
torque.
