The HS4SV cartridge valve is used to provide a variety of functions (depending on the spool chosen) thru actuation of a variety of operators available.

The HS4SV valve can be actuated by one of several (electric) solenoids, an air (pneumatic) cylinder, or a know (manual) operator. The main spool is available in several configurations. The spool is held in its normal position by a spring. Actuating the operator shifts the spool to open or close flow between various ports. Deactuating the operator allows the spring to return the spool to its original position.

Note: Port 1 must be connected directly to tank.

Valves are constructed of steel parts and operating parts are hardened as required. Cartridge is designed for easy service or field repair.
