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 procedures and parts information for the
1-inch and 2-inch Mark D and DA Series Globe and
Angle Style Control Valves. Refer to the appropriate
manuals for instructions for the accompanying actuator and additional accessories.
Trained or experienced personnel should carry out
operation and installation of all pressure equipment.
If you have any questions regarding the equipment,
contact your Jordan Valve representative.
Installation & Maintenance Instructions for the
Mark D & DA Globe and Angle Style Control Valves
3. Unless limited by existing seismic condi tions, the control valve assembly may be
installed in any position. The normal
method is with the actuator vertical above
the valve.
4. Install the valve so the process flow co-
incides with direction shown by the arrow
on the valve body.
5. Use accepted piping and welding
practices when installing the valve in the
line. For flanged valve bodies, use
suitable gaskets between the body
flanges and pipeline flanges.

Post-welding heat treatment may be required
Warning
Jordan Valve recommends the use of protective
clothing, gloves and eyewear when performing any
installation or maintenance.
Installation of the valve assembly under conditions
which exceed the limits outlined in this manual
or on the nameplate may result in personal injury.
Overpressure may cause sudden release of process pressure or bursting of assembly parts.
The valve conguration and construction materials
of each assembly are specied during ordering to
meet specic pressure, temperature, pressure drop
and controlled uid conditions. Do not operate any
part of the assembly outside of those conditions
without rst contacting Jordan Valve.
1. Before installing the valve, inspect the valve
body cavity for foreign material.
2. Remove all foreign materials such as scale or
welding slag from all pipelines.
on some valve body materials. Avoid damage
to internal elastomeric, plastic and metal parts
by removing all trim. For more information,
contact your Jordan Valve representative.
6. For screwed end connections, apply pipe
compound to pipeline threads.
7. Install a conventional 3-valve bypass
around the body to allow for continuous
operation during maintenance
and inspection.
8. If your actuator and valve body were
shipped separately, refer to the
proper Product Manual for actuator
mounting procedures.
Warning
Packing leakage could result in personal injury.
Valve packing is tightened prior to shipping
but may require readjustment to meet specic
service conditions.

Warning
Personal injury may result from sudden re
lease of any process pressure. Jordan Valve
recommends the use of protective clothing,
gloves and eye wear when performing
any installation or maintenance.
Isolate the valve from the system and relieve
pressure prior to performing maintenance.
Disconnect any operating lines providing air
pressure, control signals or electrical power
to the actuator.
Install bypass valves or completely shut
down the process to isolate the valve
from process pressure. Relieve all pressure
and drain process media from both sides of
valve.
Vent all pressure from the actuator and re
lieve pre-compression from actuator spring.
Depending on the severity of service, valve body
parts experience wear and tear and must be inspected and maintained according to conditions.
This manual includes instructions for lubrication and
maintenance of packing, trim maintenance and lapping of seating surfaces. All maintenance procedures
can be conducted while the valve remains in the line.
Note
If a gasket seal is disturbed while
removing or adjusting gasketed parts,
Jordan Valve recommends installing a new
gasket while reassembling. A proper seal
is required to ensure optimum operation.
Use lock out procedures to ensure the pro
cess remains shut down during maintenance.
Check the packing box for pressurized pro
cess uids even after the valve has been
removed from the pipeline, particularly when
removing packing hardware or packing rings,
or removing packing box pipe plug.

Packing Lubrication
An optional lubricator or lubricator/isolating valve
(Figure 1) may have been installed in place of the pipe
plug within the tapped bonnet. This is used for PTFE/
composition or other packing that require lubrication.
Use a silicon-base lubricant. Packing used in oxygen
service does not require lubrication.
Lubricator - turn the cap screw clockwise to force the
lubricant into the packing box.
Lubricator/isolating valve - open the isolating valve
before turning the cap screw to add lubricant, and
close the isolating valve after lubrication is completed.

Packing Maintenance
Contact your Jordan Valve representative for specific
packing orientation, composition and arrangements.
1. For spring-loaded single PTFE V-ring pack
ing, the spring (Key 16) maintains a sealing
force on the packing. Stop leakage around
the packing follower (Key 11) by tightening
the packing nuts. If the shoulder of the
packing box is touching the top of the bonnet
and leakage cannot be controlled, please
see “Packing Replacement.”
2. If there is packing leakage with other than
spring-loaded packing, try tightening the
packing flange nuts (Key 2) to the minimum
torque value shown in Table 1. Do not exceed
the maximum torque value shown in Table
1. Exceeding the maximum torque value may
cause excessive friction to result.
3. If the packing (Key 13) is relatively new and
tightening the packing flange nuts does not
stop the leakage; a worn or nicked valve stem
or damaged packing box bore might prevent a
proper seal. Follow the steps for Packing
Replacement and inspect the valve stem and
packing box wall during the procedure
