The Z4WEH16E63-5X/6EG24N9TK4 valve is part of Bosch Rexroth’s Z4WE Solenoid Actuation Spool Valves series and directs hydraulic flow in automation systems. With a nominal size of 16 (NG16) it handles medium-frame flows, while its CETOP D07 size matches common manifold layouts so installers can interchange it easily. The mounting interface follows ISO 4401-07-07-0-05, allowing the unit to bolt directly to standard subplates without transition blocks. A sandwich plate configuration simplifies stacking with pressure reducers or check valves in modular assemblies. Four ports provide the P, T, A, and B connections required for bidirectional cylinder control, and the E63 spool determines the internal flow paths. Two switching positions give straightforward extend-retract logic, and the matching NFPA D07 port pattern maintains alignment between international and North American standards.
Wet-pin DC solenoids shift the spool, operating on a 24 V DC supply so panels can share a common low-voltage bus. The electrical interface is a 3-pole (2+PE) EN 175301-803 connector that offers quick plug-in wiring and protective earth continuity. External pilot oil supply provides consistent actuation pressure even when main line pressure fluctuates, while internal pilot oil return routes fluid back to tank without an additional drain line. A concealed manual override, coded N9, permits local shifting during commissioning or power loss without exposing the operator to moving parts. The valve tolerates flow rates up to 300 l/min and withstands system pressures to 315 bar, letting it govern high-demand circuits without exceeding its mechanical limits.
