The Z4WEH22E63-5X/6EW110NETK4/V valve belongs to the Z4WE Solenoid Actuation Spool Valves series from Bosch Rexroth and directs hydraulic flow in automated machinery. It uses electro-hydraulic actuation; a high-power pilot stage coded 6E shifts the main spool designated E63 to create three distinct switching positions for circuit control. The pilot coil runs on 110 V AC at 50 or 60 Hz, and the K4 connector conforming to DIN EN 175301-803 provides the electrical interface. Design index 5X defines the internal build standard, while both pilot oil supply and return are routed internally under codes E and ET. The spool section is sized NG25 (W.H 22) to handle medium flow rates, and four service ports permit typical four-way operation.
System integration is carried out on a subplate because the valve follows the ISO 4401-08-08-0-05 porting pattern, letting it connect to standardized manifolds without additional tubing and simplifying replacement during maintenance. The hydraulic section withstands operating pressures up to 280 bar, a capability that allows compact circuits to run cylinders and motors that demand high force. FKM sealing, identified by code V, maintains leakage control when fluids run hot or contain aggressive additives, extending service intervals. A push-type manual override, indicated by code N, provides direct spool actuation during commissioning or power loss, so service personnel can shift the valve mechanically.
