DG4V3S0FLMFWB560

The DG4V3S0FLMFWB560 directional valve belongs to the DG4 Directional Valves series and is produced by Vickers for hydraulic automation where reliable on/off flow control is required. It uses a solenoid operated actuation type, which converts electrical signals into shifted spool positions for remote command. A coil rated at 110 VAC when supplied at 50 Hz lets the assembly tie directly to standard industrial mains without a transformer. The associated dissipation is 49 VA at 50 Hz, so panel designers can size power supplies and protection correctly. A flying lead with a 1/2 in NPT housing provides the electrical connection, allowing simple conduit routing in machinery. The spool is configured as type 0 with an open center, which passes flow back to tank when the valve is de-energized to minimize pressure buildup during standby. The FL left-hand build spool and spring arrangement sets the return spring on the left side, defining mounting orientation in manifold stacks. An ISO 4401-03 interface matches common sub-plates, reducing installation time in standardized circuits. Overall length is 5.750 in, which aids fitment within compact hydraulic blocks.

For 60 Hz regions, the same coil accepts 120 VAC and draws 48 VA, maintaining thermal limits while supporting North American grids. A plain manual override lets technicians shift the spool directly during commissioning or power loss for system venting. The valve handles a maximum flow rate of 40 L/min, ensuring adequate supply for medium-sized actuators. It withstands 350 bar on ports P, A, and B, giving headroom for high-pressure circuits without external relief devices. Petroleum oils are the specified fluid, so seal materials are selected to resist common hydraulic media. A cleanliness level of 19/17/14 limits particulate contamination to protect the precision spool fit and extend service life. The unit stands 3.570 in high, which influences envelope calculations when stacked on a manifold. The compact height also allows enclosure doors to close without interference. These parameters support predictable performance in fixed or mobile equipment that depends on directional control of pressurized oil.
