The Bosch Rexroth H-4WEH22R7X/6EG24N9S2K4 (R901147437) is an industrial hydraulic valve designed for high-performance applications, featuring robust construction and reliable operation. It is a spool valve with pilot operation, utilizing a Size 22 design, and comes with a Symbol R representation for the oil flow direction. The valve operates with an electrical connection using a Connector pole PE according to EN and has a supply voltage of 24 VDC. It is capable of handling a maximum operating pressure of up to 350 bar and allows for a maximum flow rate of 450 l/min. This particular model offers solenoid actuation with external pilot oil supply and return, ensuring precise control over the switching positions. The main control spool is held in the central position by return springs, even without pilot pressure or in vertical positioning. However, it should be noted that internal leakage is inherent to this type of valve design and may increase over its lifecycle. The H-4WEH22R7X/6EG24N9S2K4 valve also features pressure centering of the main control spool, where one centering bush fixes the control spool position within the housing. This allows for movement to the switching position by relieving pressure from one side while channeling returning pilot oil externally. For mounting purposes, this valve uses subplate mounting with connection diagrams conforming to NFPA T3.5.1 R2 D03 and ISO 4401 Size 05 standards. It includes various options such as manual override, switching time adjustment, preload valves in channel P of the main valve, stroke setting, and spool position monitoring. The Bosch Rexroth H-4WEH22R7X/6EG24N9S2K4 is suitable for electrohydraulic applications requiring reliable directional control in various configurations—whether spring or pressure centered—with options for wet-pin DC or AC solenoids. Its versatility makes it ideal for sophisticated hydraulic systems demanding precise actuation and reliable performance under high-pressure conditions.
