Four-Way Directional Pressure Compensated Control Valve

This type of four-way directional pressure compensated control valve combines the features of a four-way directional control valve, a full range pressure compensated by-pass type flow control valve, and an adjustable pilot operated pressure relief valve all in one compact package.

This valve reduces the number of fittings, plumbing and potential leakage points in hydraulic circuits. The manual handle allows the customer to meter the flow out of either port. Flow to the work port is directly proportional to the movement of the lever. Flow out of each work port is constant regardless of load changes; this allows the customer to maintain smooth and constant movement of a cylinder or motor.

Every four-way directional pressure compensated control valve comes standard with a pilot operated relief. The tank port must be plumbed directly back to tank.

The spool types of the four-way directional pressure compensated control valve are tandem center, open center, open meter center, fine metering, and tandem metering.

Standard enclosed lever handle pressurizes the port when the handle is pushed towards the valve body which should be vertical mounted. Enclosed lever handle is similar to except horizontal mount. Lever handle pressurizes the port when the handle is pushed towards the valve body. Lever handle pressurizes the port when the handle is pushed towards the valve body. Rotary handle is used to rotate spool in or out of valve body. Three-position detent holds the spool in neutral and both active positions.

Friction detent applies friction to the spool so that the spool does not move when the handle is released either side of neutral, a detent groove clearly indicates neutral position. Spring center returns the handle to neutral when the handle is released. Spring center detent springs back to neutral from one position and is mechanically detented in the other position. Spring center friction detent springs back to neutral from one direction and functions similar to standard F1 inother direction. Spring offset spring holds spool in one active position. Spring offset spring holds spool in one active position. Rotary friction detent applies friction to the spool as it is rotated so that the spool does not rotate when the handle is released either side of neutral, a detent groove clearly indicates neutral position.
