The SDG4S4012A50 valve belongs to the Directional Control Valves series manufactured by Vickers for hydraulic automation systems that require reliable flow direction. It is a solenoid-operated unit that shifts a Spool 2 element, and a spring offset returns the spool to its rest position when the coil is de-energized. The coil is rated for 115 VAC at 60 Hz, and the flying-lead connection simplifies wiring inside a control enclosure. A single-stage design reduces complexity, while the ISO 4401-05 interface aligns the mounting holes with common subplates. The valve is intended for subplate or manifold installation and seals internal passages with Buna-N elastomers suited to petroleum oils.
The housing measures 12.540 in long and 2.810 in wide, allowing the valve to fit compactly on standard hydraulic manifolds. It accommodates a maximum flow of 20.0 GPM and sustains 3000 psi on the pressure and work ports. The tank port can tolerate up to 1000 psi, permitting moderate back-pressure in return circuits. For sustained performance, system fluid must meet a cleanliness level of 20/18/15 so that the spool land clearances remain free of abrasive particles. These pressure, flow, and cleanliness limits define the operational envelope of the valve in medium-duty industrial machinery.
