Z4WEH10E68-4X/6EW110N9ETK4/B10D3V

The Z4WEH10E68-4X/6EW110N9ETK4/B10D3V valve belongs to the Z4WE Solenoid Actuation Spool Valves series and is produced by Bosch Rexroth for hydraulic automation tasks that demand reliable directional control. A nominal size of 10 defines its interface dimensions and aligns the body with standard subplates. The ISO 4401-05-04-0-05 porting pattern further guarantees that the mounting surface and port locations match common manifold layouts. With four ports, the valve offers separate pressure, tank, and two service ports for bidirectional actuator connection. Its two switching positions permit alternate routing of flow, governed by the E68 spool that establishes specific open and closed paths in each state. Continuous service is rated for 315 bar, enabling operation in high-pressure circuits without derating. A maximum flow capacity of 160 l/min supports medium-capacity cylinders and motors while maintaining acceptable pressure drop.

The integrated solenoid is wound for 110 VAC at 50 / 60 Hz, allowing direct connection to plant control power without a separate DC supply. Electrical termination is handled through a 3-pin (2+PE) EN 175301-803 connector, providing a quick-release plug with a protective earth contact. A concealed manual override designated N9 lets maintenance personnel shift the spool locally while keeping the enclosure profile flush. Both pilot supply and return are internal, coded ET, so external pilot lines are unnecessary and installation remains compact. A built-in pilot pressure reducing stage set to 45 bar, identified as D3, stabilizes the pilot circuit and prevents overloading the shifting mechanism. The optional B10 throttle insert with a 1.0 mm orifice moderates pilot flow to damp switching transients. The tank port can withstand back pressures up to 160 bar, ensuring consistent performance when return lines experience elevated pressure. An IP65 enclosure rating guards internal components from dust ingress and low-pressure water jets, while FKM seals withstand hydraulic oil and higher temperatures.
