Cla-Val products

Cla-Val Series 131 and 631 Electronic Control Valves are designed specifically for applications where remote control of valve function is preferred. They are hydraulically operated, pilot controlled, diaphragm valves. The solenoid pilot controls are actuated by electrical signals from the 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. 

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.

Cla-Val Series 131-66 and 631-66 Electronic Control Valves are designed specifically for applications where control of the valve with electrical signals 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.

Cla-Val Models 131-73 and 631-73 Electronic Interface Control Valves are well suited for applications where the line pressure is low or the media is aggressive. Independent air pressure is used to operate the valve. The pilot system applies or relieves pressure to either side of the diaphragm, causing the valve to open, close or modulate as desired. The optional VC-22D Electronic Controller is easily programmed to modulate the valve for precise control of flow, pressure, tank level or valve position.

Cla-Val Models 390-07 and 3690-07 Electronic Actuated Pressure Reducing Valve with Manual Hydraulic Bypass combine precise control of field-proven Cla-Val hydraulic pilots and simple, remote valve control. The 390-07 and 3690-07 Pressure Reducing Valves automatically reduce higher inlet pressure to a steady lower downstream pressure regardless of changing flow rate and/or varying inlet pressure.
