The 4WRZ16E100-7X/6EG24N9K4/D3V proportional directional valve belongs to the WRZ Proportional Directional Valves series from Bosch Rexroth and modulates flow for closed-loop hydraulic automation. It delivers a nominal flow of 100 l/min at a 10 bar differential, allowing moderate-capacity cylinders or motors to be driven with predictable response. The unit bolts to subplates that follow the ISO 4401-07-06-0-94 pattern, and in this mounting arrangement it weighs 13.4 kg. A pilot valve size of 6 provides the control stage that positions the main spool. Electrical power is supplied at 24 V DC; the cold coil resistance is 4.8 Ω, while up to 1.5 A can be applied to reach full spool travel.
A command value overlap of 15 % defines the neutral deadband that prevents unintended actuator movement. Continuous operation is possible because the solenoid is rated for a 100 % duty cycle, and the winding can withstand temperatures up to 150 °C without loss of function. Connection is made through a DIN EN 175301-803 plug, and the housing carries an IP65 rating to resist dust and water jets encountered in machinery enclosures. The hydraulic block tolerates working pressures to 350 bar, with 20 mm ports for the P, A, B, and T lines. The external pilot drain (port Y) is limited to 30 bar, whereas the return port T can accept up to 250 bar when connected to an external drain circuit.
