PRESSURE INDEPENDENT CONTROL VALVE PICV_IOM_REVF_0114
• Protect PICV and downstream equipment with an upstream self-cleaning strainer.
• For maximum efficiency and minimum wear install PICV IN VERTICAL POSITION with the stems POINTING UPWARD.
• Be sure to leave 6 INCHES (15.24 CM) OF CLEARANCE above the actuators to allow for actuator removal.
• Before installing, be sure PICV and piping are CLEAN INSIDE and FREE OF SCALE, chips, welding spatter, and foreign material.
Thoroughly blow out or flush pipe lines.
• The PICV must be installed with the fluid flow in the direction of the arrow on the flow arrow plate.
• Pipes must be aligned squarely with the PICV at each connection.
• Tighten flange bolts evenly to prevent excessive stress and the possibility of cracking. If mating flanges are raised faced they must be
machined flat.
• The PICV and accessories (if so equipped) are assembled, tested, and calibrated at the factory as a unit. The nameplate specifies set-up
parameters used.
• Supply air or power, instrument signal, and accessories should be connected to ports or terminals as indicated on the PICV.
• Verification and tuning of the set differential pressure may be required under actual operating conditions.
