InstallatIon

Sudden release of pressure may result personal

injury or equipment damage if the valve assembly

is installed where service conditions could exceed

the limits on the nameplates. Provide a relief valve

for overpressure protection as required by govern-

ment or accepted industry codes and good engi-

neering practices to avoid such injury or damage.

Upon ordering, the valve conguration and con-

struction materials were selected to meet particular

pressure, temperature, pressure drop, and con-

trolled uid conditions.

1. Prior to installation of the valve, inspect it and

any associated equipment for damage and

any foreign material. Ensure the valve interior

is clean, that pipelines are free of foreign

material, and that the valve is oriented so that

pipeline ﬂow is in the same direction as the

arrow on the side of the valve.

2. Typical installation of the Mark EZ control

valve is with the actuator vertical above the

valve; however it may be installed in any orien-

tation unless limited by seismic criteria. Other

positions may result in uneven valve plug

and seat ring retainer wear, and

improper operation. With some applications,

the actuator may also need to be supported

when not in a vertical position. For more infor-

mation, contact your Jordan Valve Represen-

tative.

3. Use accepted piping and welding prac-

tices when installing the valve in the line.

During the welding procedure internal

elastomeric parts may stay in place.

For ﬂanged valves, use a suitable

gasket between the valve body ﬂange

and pipeline ﬂanges.

Note:

Post weld heat treating may be required depend-

ing on valve body materials used. It is recom-

mended that all trim components be removed

if post weld heat treating is to be performed to

prevent damage to internal elastomeric and plas-

tic parts, as well as internal metal parts. Shrunk-

t pieces and threaded connections may also

loosen. Contact your Jordan Valve representative

for more information.

4. With a leak-off bonnet construction,

remove the pipe plugs (key 14) to hook up

the leak-off piping.

Install a three-valve bypass around the

control valve assembly if continuous

operation is required during inspection

or maintenance.

5. Refer to the actuator mounting procedure

in the appropriate instruction manual if the

actuator and valve are shipped

separately.

Personal injury could result from packing leak-

age. Valve packing was tightened prior to ship-

ment; however, the packing might require some

readjustment to meet specic service condi-

tions.
