CRL-33 Purchase Specifications

The Electronic Actuated Pressure Sustaining Pilot Control 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. Remote analog signal input shall be optically isolated and reverse polarity protected. 4-20 mA actuator position feed-
back output shall be supplied standard. A second command control input shall be from dry-contact switch closure for clockwise or counter
clockwise actuator rotation. Assembly shall be factory calibrated to the spring range listed below.
If power fails, the control pilot valve shall continue to control main valve to last set-point command. If the Remote Set-Point signal is lost the actu-
ator shall be 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 assembly shall be supplied with 30 feet of cable.

The Electronic Actuated Pressure Sustaining Pilot Control shall be Cla-Val Model CRL-33 as manufactured by Cla-Val, Newport Beach, CA.
