F3DG4S4016C50

The F3DG4S4016C50 directional valve belongs to the DG4 Directional Valves series produced by Vickers for hydraulic automation tasks. It regulates fluid paths by means of a sliding spool and maintains system cleanliness to ISO 20/18/15 so sensitive components avoid abrasive wear. The device is solenoid operated, and its coils accept a DC supply, allowing direct connection to electronic controllers. Four flow ways are provided to alternate pressure and return lines between two actuator ports. When power is removed, an internal spring offset returns the spool to its default position and restores the predefined flow state.

The valve attaches to a manifold with a gasket mounted interface that blocks external leakage and simplifies removal during servicing. Viton seals isolate hydraulic passages and sustain reliable sealing under typical fluid conditions. Uniform bolt compression along the gasket eliminates the need for additional sealant, enabling quick replacement on production equipment. These interface and sealing details allow the F3DG4S4016C50 to maintain consistent performance when integrated into manifold-based hydraulic systems.
