The 4WRLE16X200M-3X/G24TK0/A1M-812 valve is produced by Bosch Rexroth for the 4WRL Solenoid Valves series and is intended to meter hydraulic flow and pressure in automated machinery. Its electronics accept a nominal 24 V DC supply while remaining functional between 19 and 36 V DC, permitting operation on power systems with moderate voltage fluctuation. A maximum power consumption of 40 VA defines the load that must be provided by the control cabinet. The valve responds to a ±10 V command signal that positions the spool, and it returns a ±10 V measuring output for closed-loop monitoring. Continuous energization is permitted because the coil is rated for a 100 % duty cycle. An IP65 protection class prevents dust ingress and low-pressure water jets from affecting the electronics, and the 12 kg mass guides mounting hardware selection.
The hydraulic section tolerates 270 bar on ports p, a, and b, allowing it to manage high-pressure work lines; port X can also withstand 270 bar so the pilot stage matches main flow ratings, while ports T and y are limited to 210 bar for safe tank return. A minimum pilot pressure of 10 bar is required to shift the main spool, ensuring reliable actuation at low system load. The design accommodates up to 800 L/min, enabling control of large-volume circuits without external throttling. Hysteresis remains below 0.1 %, contributing to repeatable positioning during proportional control tasks. Fluid cleanliness must meet ISO 4406 (c) 18/16/13 to minimize wear and maintain the tight metering clearances specified for this valve.
