The 4WRTE16W5-125L-4X/6EG24ETK31/A5WB15M directional control valve belongs to the 4WRTE Directional Control Valves series and is manufactured by Bosch Rexroth. It modulates flow and pressure in closed-loop hydraulic systems for precise actuator control. The valve is supplied in nominal size 16, a rating that defines the flow capacity and interface dimensions for manifold mounting. Internal supply and return of pilot oil (ET) simplify piping because no external pilot lines are required. The built-in solenoid operates from a nominal supply of 24 VDC while drawing up to 1.6 A, producing a maximum power demand of 72 VA during full stroke actuation. Continuous service is supported by a 100 percent relative duty cycle, so the spool can remain energized without overheating when system logic calls for steady positioning. The on-board amplifier limits electrical residual ripple to 2.5 Vpp to maintain stable spool displacement under variable supply quality.
System pressure capability reaches 350 bar on ports P, A, and B, allowing the valve to control high-force cylinders. Return flow through port T can be routed externally at up to 250 bar or internally when backpressure does not exceed 10 bar, giving designers flexibility in tank line routing. Environmental sealing is rated to IP65, which protects the coil and electronics against dust and water jets. Electrical hookup is accomplished through a DIN EN 175201-804 connector coded K31, and the A5 interface accepts a ±10 V command signal so motion controllers can drive proportional spool shifts. There is an integrated spool position monitor that feeds back actual displacement to the control loop. The coil insulation tolerates temperatures up to 150 °C, and the electronics accept supply levels up to 35 VDC to accommodate voltage peaks during startup or long cable runs.
