4WRZ10W8-50-7X/6EG24N9EK4/D3V

The 4WRZ10W8-50-7X/6EG24N9EK4/D3V valve belongs to the WRZ Proportional Directional Valves series produced by Bosch Rexroth. It modulates hydraulic flow and direction in automated circuits, using proportional solenoid control for precise actuator positioning. The valve size is 10, which sets the envelope dimensions and compatible subplate patterns. It installs on a hydraulic manifold by subplate mounting, and the mounting interface follows ISO 4401-05-05-0-94 for interchangeability with standard blocks. Under a pressure drop of 10 bar the valve can pass 50 l/min, supporting medium-capacity actuators. The main ports withstand up to 315 bar so the unit can operate in high-pressure systems, while a pilot stage designated size 6 governs the spool movement for stable proportional control. The coil is energized by a 24 V DC supply, and a resistance of 4.8 Ω at 20 °C defines steady current draw and heat generation. A continuous duty cycle of 100 % allows the solenoid to remain energized without mandatory cooldown periods in cyclic machinery.

During operation the solenoid may be driven up to 1.5 A, and the winding is rated for a peak temperature of 150 °C to prevent insulation damage under sustained load. Electrical connection is made through a DIN EN 175301-803 connector, giving quick plug-in wiring in control cabinets. A concealed manual override lets maintenance personnel shift the spool mechanically without exposing the mechanism to contaminants. The separate Y port tolerates back pressures to 30 bar, permitting remote tank return arrangements. An IP65 protection rating shields the enclosure from dust and low-pressure water jets, enabling installation in typical industrial environments. FKM seals are fitted to resist mineral oils and elevated temperatures found in hydraulic circuits. Together these features complete the functional performance envelope and confirm that the valve meets proportional control requirements where accurate flow, environmental protection, and standard connector interfaces are mandatory.
