340-02/3640-02 Purchase Specifications (CDHS-33 supplement)

The Electronic Actuated Flow Control Valve shall maintain a constant flow rate and shall be capable of remotely changing this flow rate
as directed by the hydraulic rate of flow 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 isolated and reverse polarity protect-
ed. A 4-20 mA actuator feedback signal shall be supplied as standard. A second command control input shall be available from dry con-
tact switch closure for clockwise and counter clockwise rotation. The actuator shall be IP-68 rated for submersible service.
If a power fails, the pilot shall continue to control the main valve to last set point. If the remote set point signal is lost, the actuator is pro-
grammable 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 accom-
plished by using only the manufacturer’s software and USB cable.
The Electronic Actuated Flow Control Valve shall be Cla-Val Model 340-02/6340-02 as manufactured by Cla-Val, Newport Beach, CA.
