The 4WRZE10EA85-7X/6EG24N9EK31/A1D3M proportional valve is built by Bosch Rexroth for the WRZ Proportional Directional Valves series. Intended to meter flow and shift actuator direction in hydraulic automation, it delivers a nominal flow of 85 l/min at a 10 bar pressure drop to match medium-size cylinders and motors. The main stage tolerates up to 315 bar so it can be placed directly in high-pressure lines. A pilot valve size 6 is integrated to actuate the spool with low control effort. Interface conformity is secured by the ISO 4401-05-05-0-94 porting pattern, allowing the body to bolt to standard subplates. Command signals arrive as ±10 V, giving motion controllers an analog window for bidirectional stroke control. Internal electronics are powered from a 24 V DC supply, and the coil draws at most 1.8 A; a cold resistance of 4.8 Ω confirms this current level. Together these electrical figures guide power-supply selection and ensure predictable magnetic force.
For continuous duty the solenoid is rated at a 100 % duty cycle, so the valve can remain energized without imposed rest periods. Copper windings may reach 150 °C, a limit that establishes cabinet ventilation and over-current protections. When an external drain is used, the tank port also withstands 315 bar, while the Y port is restricted to 30 bar to protect the pilot section. Sealing against hydraulic oil is provided by NBR material, which is compatible with common mineral fluids and maintains elasticity over the specified temperature range. Electrical hookup is through a DIN EN 175201-804 connector that simplifies field replacement. A concealed manual override is present, allowing technicians to shift the spool mechanically during commissioning while preventing accidental actuation in service. Overall mass is 8.0 kg, light enough for direct mounting on manifold blocks yet substantial enough to dampen vibratory loads.
