The F3DG4S4012A50 is a directional valve produced by Vickers within the DG4 Directional Valves series. It directs hydraulic flow in automated machinery where electric control of the spool is required. The valve is solenoid operated, so an electromagnetic coil shifts the spool when energized. The coil is rated for a 115 VAC 60 Hz supply, allowing direct connection to standard North American control transformers. A flying lead coil forms the electrical connection, giving installers flexible routing to junction boxes. Coil energization is identified under ANSI B93.9, which clarifies pin assignment and safety limits for interchangeable coils. The unit follows a single-stage design, eliminating pilot sections to keep response time short. During operation it tolerates up to 210 bar system pressure, while a maximum flow of 75.7 L/min establishes the throughput it can pass without excessive pressure drop. A spring offset arrangement returns the spool to its neutral location once the solenoid is de-energized.
For mounting in power units, the valve conforms to the ISO 4401-05 interface and is intended for subplate or manifold installation, so no pipe work is needed between ports. Overall length measures 241.300 mm and width is 71.374 mm, dimensions that determine stack spacing inside compact hydraulic blocks. The tank port is rated for 70 bar, allowing moderate back-pressure without damaging the housing or seals. Acceptable fluid temperatures range from 20 °C to 50 °C, matching typical reservoir conditions in industrial plants. The design omits a manual override, so spool movement depends solely on electrical actuation.
