DG5S4-02-2A-2-T-M-FPM4WL-D7-HL7-30-EN623

The DG5S4-02-2A-2-T-M-FPM4WL-D7-HL7-30-EN623 valve belongs to the DG5 Two-Stage Directional Valves series and is manufactured by Vickers for hydraulic automation that requires accurate flow direction control. It uses a two-stage pilot-operated arrangement, so a small pilot spool shifts the main stage for reduced solenoid load and smoother response. The unit is built to the D02 size, aligning its port pattern with NFPA standard subplates. A maximum flow capacity of 115 L/min (30 gpm) defines the volume it can redirect without excessive pressure drop, while a pressure rating of 210 bar (3000 psi) sets the allowable inlet pressure for the working ports. Subplate or manifold mounting lets system designers remove plumbing bends and place the valve close to actuators. An encapsulated coil rated at 24 VDC and 30 W provides the magnetic force for spool actuation, and a 4-pin Brad Harrison connector supplies quick electrical hookup. An integral indicator light shows when the coil is energized, and a plain manual override allows technicians to shift the spool during setup or power loss.

The hydraulic return side is protected by a tank port rating of 100 bar (1450 psi), allowing moderate back-pressure without risking seal extrusion or spool sticking. Viton sealing resists petroleum-based oils and elevated temperatures, matching the specified fluid compatibility with standard petroleum oils used in industrial power units. Operation within a cleanliness level of 20/18/15 according to ISO 4406 limits abrasive wear on the precision-ground spool and body. The acceptable ambient and fluid temperature extends from −18 °C (0 °F) to 65 °C (150 °F), enabling year-round service in unheated or warm machine rooms. These environmental limits, together with the stated pressure and flow capabilities, ensure repeatable performance when the valve is integrated into automated presses, injection molding machines, or mobile work platforms. By combining the pilot stage, defined temperature window, and contamination limits, the valve maintains stable shifting forces and prevents leakage across the full operating envelope.
