Represented By:
CDHS-32 Purchase Specifications
The Electronic Actuated Rate of Flow Control Pilot shall have an integral hydraulic pilot and electronic controller contained in a IP-68 rated
submersible enclosure to provide interface between remote telemetry and valve set-point control. It will compare a remote analog command
signal with an internal position sensor signal and adjust the hydraulic pilot control spring mechanism to a new set-point position. 4-20 mA
actuator position feedback output shall be supplied standard.
If power fails the valve shall continue to control to the last set-point command. If the Remote Set-Point signal is lost the actuator is
programmable to go to either the 4mA, Last, or 20mA command set-point. No mechanical adjustments shall be necessary to the
actuator. The low and high position range adjustment shall be accomplished only with valve manufacturer's components and
instructions to be supplied in a separate kit.
The Electronic Actuated Rate of Flow Pilot Control shall be Cla-Val Model CDHS-32 as manufactured by Cla-Val, Newport Beach, CA.
Ranging software makes it easy to set low (4mA) and
high (20mA) set-point limits.
