DG4S4012CUH60S306

The DG4S4012CUH60S306 valve belongs to the DG4 Directional Valves series manufactured by Vickers for hydraulic automation circuits. It changes flow paths by moving an internal spool through solenoid-operated actuation, allowing electrical control of cylinder or motor direction. The installed coil is rated for 24 VDC, so it can be driven from standard machine control power supplies. An ISO 4400 (DIN 43650) connector provides a quick-disconnect electrical interface and maintains ingress protection at the coil housing. Hydraulic mounting follows the ISO 4401-05 / NFPA D05 pattern, making the unit interchangeable with other D05 components. The valve fits on a subplate or manifold, so piping changes are minimal during servicing. A single-stage construction links the solenoid force directly to the spool for rapid response. The internal geometry is designated as Spool 2, defining the open and closed lands for typical A-B to P-T crossover. A spring-centered three-position arrangement returns the spool to a neutral block position when the solenoid is de-energized.

This directional valve supports a maximum flow rate of 25.0 gpm, which suits medium-capacity hydraulic power units. The pressure boundary is rated for 3600 psi, allowing safe operation in high-pressure industrial systems, while the tank port can tolerate back pressure up to 1000 psi without affecting spool movement. Buna-N seals are installed to provide compatibility with standard petroleum-based fluids and to limit external leakage. Continuous service is permitted at ambient or fluid temperatures up to 50 °C, matching typical machine room conditions. The body measures 3.850 in in height, 241.300 mm in length, and 65.532 mm in width, dimensions that help designers plan stack layouts on manifold rails. These physical limits, combined with the flow and pressure capabilities, define how the DG4S4012CUH60S306 integrates into automated presses, injection-molding machines, or other equipment requiring reliable directional control.
