The 4WRZE16W8-100-7X/6EG24N9ETK31/F1D3M is produced by Bosch Rexroth as part of the WRZ Proportional Directional Valves series. It regulates actuator speed and directional change in hydraulic automation systems where proportional flow control is required. The unit passes 100 l/min at a pressure drop of 10 bar, giving predictable flow for medium-size drives. It withstands operating pressures up to 350 bar so it can be installed in high-pressure circuits. Subplate mounting allows quick removal while leaving manifold pipework untouched. The porting pattern follows ISO 4401-07-06-0-94, which aligns the valve with standardized hydraulic bases. A size 6 pilot stage with internal oil supply and internal drain simplifies plumbing and keeps the envelope compact.
The solenoid operates from a 24 V DC supply that matches common machine control power rails. A coil resistance of 2 Ω at 20 °C and a current limit of 2.5 A define the electrical load presented to the driver. Continuous service is supported by a 100 percent duty cycle, while insulation allows coil temperatures up to 150 °C without degradation. Connection is made through a DIN EN 175201-804 plug, enabling fast exchange during maintenance. A concealed manual override permits local spool shifting when power is absent yet prevents inadvertent activation during operation. An IP65 rating keeps dust and water jets away from energized parts. NBR seals maintain compatibility with standard hydraulic oils and control external leakage.
