4WRLE16V200M-3X/G24TK0/A1M

The 4WRLE16V200M-3X/G24TK0/A1M valve belongs to the 4WRL Solenoid Valves series and is manufactured by Bosch Rexroth. It is an electrically actuated directional control unit used to meter hydraulic flow and pressure in automated circuits. The valve is built in nominal size 16, allowing it to handle large system lines while maintaining responsive spool movement. It supports a maximum flow of 800 l/min so it can supply high-volume actuators without excessive pressure loss. The pressure ports p, a, and b tolerate up to 270 bar, enabling operation in heavy-duty power drives, and the zero-stroke leakage is limited to 2.3 l/min to reduce energy loss during idle positions. A pilot stage requires at least 10 bar to shift the main spool, ensuring reliable actuation under low supply conditions. The solenoid accepts a 24 VDC supply and is rated for a 100 % duty cycle, which permits continuous energization in closed-loop control tasks. Command input is provided as a ±10 V differential signal that interfaces with standard servo amplifiers.

The electronic interface presents an input resistance of 100 kΩ to minimize loading on the controller outputs. During spool movement the pilot network draws 11.5 l/min of oil, a value that must be accounted for in pump sizing. The tank and y lines withstand up to 210 bar, protecting the housing against back-pressure spikes common in regenerative circuits. Approved hydraulic fluid temperature ranges from –20 to +70 °C, enabling service in mobile and industrial equipment exposed to seasonal variation. The solenoid coils consume a maximum of 40 VA, simplifying power provision inside control cabinets. All dynamic seals are produced from NBR to suit common mineral oils and assure compatibility with the specified temperature band. An IP65 protection class shields the coil and connector against dust ingress and low-pressure water jets, supporting installation on machinery without additional enclosures.
