Product Overview
The Rexroth H-4WH 16 U7X//S06 (Material No. R900960545) is a hydraulically operated directional spool valve from the proven 4WH series, designed for high-flow industrial hydraulic systems. Actuated by external pilot pressure rather than solenoids, this valve uses a precision-ground spool within a rugged cast housing to route, stop, and release pressurized fluid across multiple work ports. Its hydraulic pilot actuation makes it particularly suited to applications requiring remote control, high switching forces, or use in hazardous environments where electrical actuation is impractical. The size 16 (NG16) designation indicates a nominal flow capacity of approximately 300 L/min, positioning this valve for demanding circuits in heavy machinery and process equipment.
