InstallatIon

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 conguration and construction materials

of each assembly are specied during ordering to

meet specic 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.

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 specic

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.
