The H-4WEH10E4X/6EW110N9ETK4/B10D3 valve belongs to the WEH Directional Spool Valves series from Bosch Rexroth and directs hydraulic flow in automated machinery. As an NG10, 4-way unit, it channels pressure and tank lines to two actuator ports for bidirectional motion control. The ISO 4401-05-05-0-05 porting pattern matches common subplates, and a maximum operating pressure of 350 bar permits use in high-pressure circuits. Flow capacity reaches 160 l/min under symbol E, supporting medium-size cylinders without excessive pressure loss. Internal pilot oil supply and return eliminate external hoses, while a minimum pilot pressure of 12 bar ensures reliable spool centering when springs are fitted.
The pilot stage tolerates up to 250 bar, and a 1.0 mm throttle insert moderates pilot flow to prevent shock during shifts. A concealed manual override (N9) lets technicians move the spool mechanically when electrical power is absent. Solenoid wiring connects through a DIN EN 175301-803 K4 plug that provides strain relief and polarity guidance. NBR seals contain hydraulic oil and resist common additives, whereas cleanliness class 20/18/15 limits particulate ingress for long service life. The valve offers an MTTFd of 100 years, indicating high reliability in safety-related controls. An internal pressure-reducing valve fixed at 45 bar shields the pilot circuit from system surges.
