INSTALLATION
Recommended Piping: ANSI 125 Flanges should mate with piping with 125 Lb or 150 Lb
Flat Faced Flanges.
Per ISA Recommended Piping Practices. Control valves perform best with a reasonable
amount of upstream and downstream straight pipe prior to elbows and strainers. The
general specification for this is 16 pipe diameters upstream of straight pipe and 5 pipe
diameters downstream of straight pipe as minimums. However, this is a broad specification
covering all pipe diameters and velocities. Many applications do not have this kind of
space. While more length of straight pipe is desirable, Warren Controls has produced a
table of minimum pipe diameters for use on our PICV. Failure to follow these guidelines
may lead to noticeable vibrations or noise for excessive turbulence in some applications
with significant head pressure. In the unlikely event of excessive noise or vibration, other
remedies like special low noise trim may be available but at the expense of the user or
installer when not following installation guidelines.

The above tables are recommended minimum lengths for good and stable performance. Wherever possible, longer runs of straight pipe
should be used for optimal performance and stability.
• Be sure that the flow medium, ambient temperature and the selected location will not exceed the maximum temperature of the PICV,
actuator, or accessories. Information can be found on the nameplate and product specifications regarding these limits.
• Check PICV for any damage due to improper storage or transportation. Immediately notify your sales organization of any damaged
goods upon receipt. Do not attempt to move or disturb them further so photos may be taken. If the shipping container is noticeably
damaged, refuse receipt as the shipping company should be held liable, until a shipping representative is available to take photos.
• Verify that the PICV is visually in good working order – not bent or cracked.
• Follow good piping practices. Install a bypass around the PICV. Install stop valves in inlet and outlet piping to provide means to isolate
PICV.
• THE PICV SHOULD BE INSTALLED AS A UNIT. THE SEGMENTS SHOULD NOT BE SEPARATED FOR INSTALLATION.
• Carefully remove the PICV from shipping crate with a portable hoist or crane. The PICV is too heavy for one or even two people to lift
and hand-install depending on size. The Crane or Hoist should use a strap or chain cradle around the central flanges of the two valve
assemblies to raise and maneuver the PICV into position at the pipe flanges. Efforts should be made to avoid damaging the sensing
lines and actuators during this installation procedure.
