Cla-Val 131-22/631-22 Electronic Interface Control Valves are designed specifically for applications where remote control of the valve is preferred. It is a hydraulically operated, pilot controlled, diaphragm valve. The solenoid pilot controls are actuated by electrical signals from the optional VC-22D Electronic Valve Controller. The solenoid pilots either add or relieve line pressure from the cover chamber of the valve, causing it to open or close as directed by the electronic controller, making it ideal for reservoir filling operations.
131-22/631-22 Electronic Control Valves can be configured to perform a wide range of functions, such as; pressure reducing, pressure sustaining, flow control or level control. The electric controls can also be combined with hydraulic controls to create dual function or fail-safe capability.
