The DG5V-10-H-33C-E-M-FW-B-1 valve belongs to the DG5 Two-Stage Directional Valves series manufactured by Vickers and is intended to route flow in hydraulic automation systems. A high performance pilot valve actuates the main spool for quick response, and the body attaches to manifolds using the ISO 4401-10 interface. A 1/4 BSP gauge port thread accommodates standard pressure gauges, while an external pilot supply lets designers feed the control stage from an independent line. When spool 33 operates at 210 bar, the valve can pass 1022 L/min (270 gpm), and all ports are rated for a maximum operating pressure of 350 bar (5000 psi). Overall dimensions of 419.1 mm in length and 190.5 mm in width help determine the required mounting space.
At 350 bar, spool 33 provides a flow capacity of 757 L/min (200 gpm) to maintain actuation speed at higher system pressure. An external pilot drain isolates the control section from return-line back-pressure, and the tank line may reach 210 bar (3000 psi) without compromising function. Shifting toward port A at 946 L/min needs a minimum pilot pressure of 10 bar (150 psi), while movement toward port B at the same flow requires 27.5 bar (400 psi); these figures guide pilot circuit design. The mounting pattern matches NFPA D10 blocks, easing integration with existing manifolds. A height of 254.5 mm (10.02 in) and a weight of 45.4 kg (100 lb) inform handling, support, and enclosure planning.
