390-02/3690-02 Purchase Specifications (CRD-33 supplement)

The Electronic Actuated Pressure Reducing Valve shall maintain a constant downstream pressure and shall be capable of remotely
changing this pressure as directed by the hydraulic pressure reducing pilot and integral electronic actuator. The actuator shall provide
the interface between remote telemetry and valve set point control. It shall compare a remote analog signal with an internal position
signal in the actuator and adjust the hydraulic pilot spring mechanism to the new setting. The remote analog signal input shall be iso-
lated and reverse polarity protected. A 4-20 mA actuator feedback signal shall be supplied as standard. A second command control
input shall be available from dry contact switch closure for clockwise and counter clockwise rotation. The actuator shall be IP-68 rated
for submersible service.
If power fails, the pilot shall continue to control the main valve to last set point. If remote set point signal is lost, the actuator shall be
programmable to stay at last position or go to 4 mA or to 20 mA value of set point range. Default is last position. The actuator shall
be ranged at the factory to the specific spring range in the pilot control. If other than the default settings are required, these changes
shall be accomplished by using only the manufacturer’s software and USB cable.
The Electronic Actuated Pressure Reducing Valve shall be Cla-Val Model 390-02/3690-02 as manufactured by Cla-Val, Newport Beach, CA.
