The 4WRTE16E1-125L-4X/6EG24K31/A1M valve is produced by Bosch Rexroth and belongs to the 4WRTE Directional Control Valves series for proportional hydraulic flow control. It receives a nominal 24 V DC supply voltage that powers its onboard spool-position electronics. A ±10 V command input provides the control signal, allowing integration with standard analog controllers, and the input circuit presents 100 kΩ resistance so the signal source is lightly loaded. Maximum current draw is 1.6 A, which defines the rating of cabinet power supplies, and an external 4 A time-delay fuse must be used for overcurrent protection. Electrical connection is made through a DIN EN 175201-804 K31 plug, ensuring compatibility with common wiring harnesses. The housing carries an IP65 protection class so it resists dust ingress and water jets in industrial plants. The assembly weighs 11.2 kg, a figure that affects manifold support and handling procedures.
The valve regulates flow up to a recommended 460 l/min, supporting high-capacity circuits, while ports P, A, and B withstand operating pressures to 350 bar for heavy-duty service. The return line T can accept 250 bar externally, and the static Y port is limited to 10 bar; these limits guide tank-line design. Pilot oil is supplied internally and returned externally, a layout that simplifies supply plumbing while isolating return flow, and the pilot stage draws 14 l/min when moving from 0 to 100 percent command, which influences pump sizing. Maximum hysteresis is 0.1 percent, ensuring precise spool repositioning during small signal reversals, and a response sensitivity of 0.05 percent allows fine resolution of flow adjustments. These performance figures enable smooth directional control across the load range without oscillation.
