H-4WEH32J6X/6EG24N9S2DAL

The H-4WEH32J6X/6EG24N9S2DAL valve belongs to the WEH Directional Spool Valves series manufactured by Bosch Rexroth for hydraulic automation tasks that require precise control of high-flow circuits. It is supplied in nominal size 32, allowing large passage areas suited to presses, molding machines, or heavy mobile equipment. A porting pattern of ISO 4401-10-09-0-05 matches standard subplates so installation time is minimized. The valve carries spool symbol J, and with this configuration it reaches a maximum flow of 680 l/min at 350 bar to shift significant oil volumes without excessive pressure drop. The same pressure value of 350 bar defines the maximum operating limit on ports P, A, and B, ensuring durability in high-pressure lines. Coil actuation relies on a rated voltage of 24 V DC, enabling direct connection to common machine control supplies. A concealed manual override lets maintenance staff reposition the spool during commissioning while protecting the push pin from accidental use. System cleanliness must stay within ISO 4406 code 20/18/15 to keep the precision-ground lands free from wear and sticking.

The pilot stage tolerates up to 250 bar so upstream logic valves or accumulators can drive the spool without damage, and it still functions down to a spring-centered minimum of 8.5 bar for low-pressure start-ups. Port T accepts return pressures as high as 250 bar, permitting backpressure in regenerating circuits, while port Y, when used for external drainage, is limited to 210 bar to protect the pilot housing seals. Six mounting screws sized M20 × 80 secure the body to the manifold, and each screw must be tightened to 340 Nm to maintain the sealing edge under full load. With both solenoids and the spring-centering assembly fitted, the valve weighs 41.0 kg, a consideration when designing support brackets or when handling the unit during service. The mean time to dangerous failure is calculated at 100 years, indicating a long statistical service life in duty cycles that comply with the stated pressure and flow ratings.
