The 4WRLE27Q4-430M-3X/G24TK0/A1M valve is produced by Bosch Rexroth in the 4WRL Solenoid Valves series. It controls pressure-compensated flow for hydraulic automation loops. The interface accepts a command input of ±10 V and returns an actual value output of ±10 V for closed-loop monitoring. Electrical load is limited to 40 VA when supplied with 24 VDC, and the electronics tolerate a residual ripple of 2.5 Vpp on that line. The design supports a 100 % relative duty cycle, and the solenoid surface may rise to 120 °C during continuous operation. Hydraulic capacity reaches a maximum flow of 1850 l/min, but the pilot stage requires at least 10 bar to shift the main spool reliably.
The assembly is built in size NG 27 and matches the ISO 4401-08-08-0-05 porting pattern for subplate mounting. Under nominal conditions it delivers a rated flow of 430 l/min, while ports T and Y can withstand pressures up to 250 bar. The enclosure carries an IP65 protection class, enabling use in dusty or wet industrial areas when the connector is installed correctly. Fluid entering the valve must meet cleanliness class ISO 4406 18/16/13 to prevent wear of the metering edges. Total weight is 21 kg, so the mounting surface must support that mass without distortion.
