F3-DG4V4-012N-M-PA5WL-B5-10

The F3-DG4V4-012N-M-PA5WL-B5-10 directional valve is manufactured by Vickers as part of the DG4 Directional Valves series, serving as a control element that shifts hydraulic flow paths in automated systems. It is solenoid operated so electrical signals can actuate the spool without mechanical linkage. The coil accepts 110 VAC at 50 Hz or 120 VAC at 60 Hz, allowing use on standard industrial power lines in different regions. Under steady energization the coil draws 37 W, which defines the load placed on the control circuit. An energization time of 22 ms lets the valve reach its commanded position quickly during cycle changes. Wiring is completed through a 5-pin PA5 connector, simplifying plug-in installation and maintenance. A built-in indicator light shows coil status to aid troubleshooting during commissioning and service. The body mounts on an ISO 4401-05 / NFPA D05 interface so it pairs with manifolds and subplates that follow this footprint. Inside the body a spool type 2 defines the specific flow paths provided when the valve shifts.

The main flow paths for ports P, A, and B are rated for 315 bar (4500 psi), providing headroom for high pressure circuits common in industrial presses and mobile machinery. The tank port withstands 120 bar (1750 psi) so back pressure in return lines will not compromise sealing integrity. A maximum flow of 30 gpm, equal to 115 L/min, limits the pump size that can be routed through the valve without excessive pressure drop. The hydraulic fluid must meet ISO 4406 cleanliness class 20/18/15, a requirement that reduces wear on the spool lands and seals. Viton seals are fitted, enabling compatibility with high temperature oils and many synthetic fluids. Continuous operation is permitted up to 50 °C, while the minimum operating temperature is 20 °C, defining the fluid temperature window for reliable actuation. The detented arrangement without a spring holds the spool in its last position after power is removed, eliminating the need for constant coil power to maintain state.
