The 4WEH22E7X/6EG24N9ETDAL/B10 valve is produced by Bosch Rexroth for the WEH Directional Spool Valves series and directs hydraulic flow in automated machinery. It is built in nominal size NG25 (W.H 22), providing passage dimensions suited to high-capacity manifolds. A porting pattern of ISO 4401-08-08-0-05 lets the unit mount on standard subplates without adapters. The valve withstands 280 bar at pressure ports P, A, and B, enabling operation in systems with elevated working pressure. A maximum flow rating of 450 l/min for spool symbol E supports cylinders and motors that draw large volumes of oil. Internal pilot oil supply (ET) removes the need for an external pilot line, while internal pilot oil return (T) sends pilot oil back through the common return passage. The 24 V DC pilot solenoid matches typical machine control voltages. Fluid cleanliness must remain at ISO 4406 class 20/18/15 to prevent spool sticking and wear.
The pilot circuit tolerates up to 210 bar, allowing dependable actuation when main pressure is high, and port T accepts 250 bar to accommodate transient return surges. A minimum pilot pressure of 10.5 bar is required for spring-centered shifting so that the spool moves to each position without hesitation. Pilot volume is 7.64 cm³ on spring-centered versions, indicating the amount of oil the control stage must deliver during each changeover. NBR sealing allows a maximum fluid temperature of +80 °C and limits ambient temperature to +50 °C around the coil housing. A concealed manual override designated N9 permits emergency operation without exposing the push pin to accidental activation. When damping of pilot flow is needed, a Ø1.0 mm throttle insert coded B10 can be installed to reduce shift shock in sensitive circuits.
