The F3-DG4S4-016B WB50 directional valve belongs to the DG4 Directional Valves series and is manufactured by Vickers. Intended for hydraulic automation, it shifts oil flow between actuator ports when its solenoid is energized. The valve is solenoid operated, allowing electrical signals to command spool movement from a remote controller. Its coil supports 110 V at 50 Hz, 115 V at 60 Hz, or 120 V at 60 Hz, so common industrial power feeds can be used without transformers. The internal spool provides a 4-way flow path, giving pressure and return connections to both sides of a cylinder for bidirectional motion. A spring-centered layout with one solenoid returns the spool to neutral when power is removed, maintaining hydraulic balance. The body follows the ISO 4401-05 interface to match standard subplates, and the subplate or manifold mounting style lets the unit be installed in stacked valve banks. A wet armature with a non-serviceable core tube keeps the solenoid immersed in oil, which dampens noise and eliminates periodic core replacement tasks.
The valve works with petroleum oils, and Viton F3 seals provide the needed compatibility with these fluids at elevated temperatures. It handles system pressures up to 3000 psi while limiting the tank port to 1000 psi to protect return lines from excess backpressure. Flow capacity is rated at 20 gpm, so the valve suits medium-size actuators without excessive pressure drop. Reliable operation is maintained between 20 °C (70 °F) and 50 °C (122 °F), supporting typical machine room environments. These limits, together with the hydraulic ratings, allow the F3-DG4S4-016B WB50 to perform consistent directional control duties in power units that conform to DG4 series parameters.
