Product Details:

REXROTH 4WEH22J7X/6EW110N9K4 belongs to WEH series two-stage pilot operated 4/3 electro-hydraulic directional spool valve. Size NG25, B05 subplate mounting pattern, J spool function, 7X component series, 6EW high-power AC pilot solenoid, 110V AC supply voltage, N9 concealed manual override, K4 standard NBR sealing set. This heavy-duty hydraulic valve is designed for large-flow direction control in heavy industrial hydraulic circuits.

This valve adopts two-stage pilot control principle. The pilot solenoid valve drives the main spool by pilot oil pressure to switch the flow direction of main hydraulic circuit. For J spool function, P to A and B to T at one working position; P to B and A to T at the other working position; all ports closed at neutral position. The wet armature AC solenoid provides stable driving force and strong anti-interference ability. Separate power wiring reduces electromagnetic interference from servo drives and harsh workshop environment.

The valve body is made of high-strength cast iron, with dynamically balanced main spool and precision matched sleeve. Standard NBR seals are suitable for mineral hydraulic oil, FKM seals are optional for high temperature or special media. Maximum working pressure of P/A/B ports reaches 315 bar, T port backpressure limit 210 bar, rated flow up to 1100 L/min. Vibration-resistant structure and low-leakage spool design ensure stable repeated switching performance.

All units pass strict factory inspection before shipment, including pressure tightness test, switching response test, internal leakage test and fatigue cycle test, to adapt to long-time multi-shift heavy-load hydraulic production.

It is widely used on large hydraulic presses, die casting machines, heavy injection molding machines and metallurgical forging equipment. Typical application scenarios include large hydraulic cylinder direction control, spare replacement for aging Rexroth hydraulic systems and hydraulic machine retrofit. Automation integrators select this Rexroth valve for its high-flow capacity and classic 110V AC J spool configuration.
