The DG5S-8-2A-M-FTWL-B5-30 is produced by Vickers in the DG5 Two-Stage Directional Valves series. It directs hydraulic flow in automated circuits that need dependable actuation of cylinders or motors. The spool 2 pattern keeps every port closed to tank, enabling positive load holding when the coil is de-energized. A spring offset to the A port returns the spool to a known position after power is removed, ensuring predictable standby flow paths. Internal pilot supply removes the need for an external pressure line, while an external Y port handles pilot drain so case pressure remains low. Rated pressure at the P, A, and B ports reaches 210 bar, aligning with common industrial power units, and the pilot stage tolerates tank pressure up to 100 bar. Recommended flow of 170 L/min promotes stable response, yet the design passes up to 380 L/min without malfunction when transient demand rises. The flying-lead coil accepts either 110 VAC at 50 Hz or 120 VAC at 60 Hz, allowing installation on global mains.
Installation details support quick integration into manifolds. The ISO 4401-08 (NFPA D08) mounting interface matches standard sub-plates, and mounting bolts are tightened to 79 N·m to secure the body against pressure-induced forces. Tank port pressure may rise to 210 bar without damaging the housing, so the unit fits high-pressure return circuits. A wired terminal block provides a straightforward electrical connection for control signals, and the 1/2 NPT threaded wiring housing admits flexible conduit to protect leads on mobile machinery. Total mass is 15.0 kg, so a single technician can place the assembly while maintaining alignment with pilot lines.
