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 pro-
cess pressure or bursting of assembly parts.
The valve configuration and construction materials
of each assembly are specified during ordering to
meet specific pressure, temperature, pressure drop
and controlled fluid conditions. Do not operate any
part of the assembly outside of those conditions
without first 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.
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.
Note
Post-welding heat treatment may be required
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 specific
service conditions.
Warning: Jordan Valve Control Valves must only be used, installed and repaired in accordance with these Installa-
tion & 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 disassem-
bling a valve, be sure to release all spring tension.
