The 4WRLE10Q5-85M-3X/G24ETK0/A1M valve belongs to the 4WRL Solenoid Valves series and is produced by Bosch Rexroth for closed-loop hydraulic automation. It is powered by a 24 VDC supply, and the coil draws up to 40 VA at full excitation, allowing engineers to size control cabinets accurately. A differential ±10 V command input sets spool position, while an internal ±10 V test output provides feedback for diagnostics without external sensors. A 2.5 A time-delay fuse protects the electronics against over-current events. Continuous energization is permissible because the relative duty cycle is 100 percent. The housing is rated IP65, so the assembly resists dust and low-pressure water jets when the connector is installed. During prolonged operation the solenoid surface may reach 120 °C, so adjacent components must tolerate that temperature.
In the hydraulic circuit, the valve sustains 280 bar on ports A, B, and P, matching the same 280 bar limit assigned to pilot port X. Return ports T and Y are limited to 250 bar to protect tank lines. The metering section passes up to 300 l/min so large actuators can move at design speed. A pilot pressure of at least 10 bar is required to shift the spool reliably under all load conditions. Fluid temperature may rise to 70 °C without impairing service life, provided viscosity remains below 380 mm²/s. System oil cleanliness should reach ISO 4406 code 18/16/13 to prevent spool wear and sticking.
