The DG5SH86CTMWB50 valve is produced by Vickers for the DG5 Two-Stage Directional Valves series and serves to switch hydraulic flow in automated machinery. It is a pilot-operated 4-way directional valve, enabling four discrete flow paths for cylinders or motors. A type 6 spool keeps port P closed while ports A and B open to tank, which vents work lines during standby. The spring-centered design returns the spool to neutral when pilot pressure is lost, giving automatic re-centering. A recommended flow of 265 L/min (70 US gpm) defines the throughput that avoids excessive pressure drop. Main ports withstand 310 bar (4500 psi) so the unit suits high-pressure circuits, while the spool begins to shift at a pilot pressure of 8 bar (120 psi) at rated flow. An internal pilot drain routes leakage directly to tank, simplifying external plumbing. Installation matches the ISO 4401-08 (NFPA D08) pattern so the valve bolts onto standard subplates without adapters.
Electrical actuation is provided by solenoid coils rated at 110 VAC, 50 Hz, allowing direct connection to common control power. Each coil terminates on a terminal block for straightforward wiring, and a 1/2 NPT conduit entry offers a sealed path for cables. The tank port tolerates back pressure up to 210 bar (3000 psi), maintaining performance when return lines are restricted. Pilot passages can accept up to 310 bar (4500 psi) without damaging the control stage, and the spool reaches full stroke once pilot pressure rises to 10 bar (150 psi) when maximum flow is required. Proper seating of the valve to its subplate demands tightening the mounting bolts to 79 N·m (700 lbf·in). The two-solenoid assembly weighs 17.3 kg, a factor considered during handling and manifold support design. These electrical, pressure, and mechanical limits establish safe integration of the DG5SH86CTMWB50 valve within hydraulic automation systems.
