CPC Purchase Specifications
The Electronic Actuated Positioning Pilot Control shall have an integral hydraulic pilot and electronic controller contained in an IP-68
rated submersible enclosure to provide interface between remote telemetry and valve position control. It will compare a remote analog
command signal with an internal position sensor signal and adjust the hydraulic pilot control mechanism to a new valve position. Remote
analog signal input shall be optically isolated and reverse polarity protected. 4 - 20 mA actuator position feedback output shall be sup-
plied standard. The valve assembly and all components shall be rated for continuous duty.
If power fails, the control pilot valve shall continue main valve control to last set-point command. If the remote position signal is lost the
actuator shall be programmable to go to either the 4 mA, Last, or 20 mA command positions. No mechanical adjustments shall be nec-
essary to the actuator. The low and high position range adjustment shall be accomplished only with valve manufacturerʼs components
and instruction to be supplied in a separate kit.
The Electronic Actuated Positioning Pilot Control shall be Cla-Val Model CPC as manufactured by Cla-Val, Newport Beach, CA.
CPC Electronic Actuator Specifications
• Programmable USB connection cable when changing
range parameters or restoring range parameters after servic-
ing pilot control subassembly.
Options:
• Re-ranging software - free download from www.cla-val.com.
Ranging software makes it easy to set low (4mA) and
high (20mA) set-point limits.
CPC Programming
• Provides Dynamic Readings
• Dead Band Prevents Actuator from reacting to minor signal
fluctuations
• Enables customers to verify “clean” input signal from SCADA.
Pressure Connection 3/8" NPT
Valve Connections: Positioning Pilot mounting
thread to match valve
cover center port.
Temperature Range
Water: to 180°F
