4WRTE16W6-200L-4X/6EG24K31/F1V

The 4WRTE16W6-200L-4X/6EG24K31/F1V is a directional control valve produced by Bosch Rexroth within the 4WRTE Directional Control Valves series. It modulates hydraulic flow and pressure for automated actuators in industrial machinery. The NG16 size defines the mounting footprint and matches standard subplates for medium-capacity circuits. A porting pattern conforming to ISO 4401-07-07-0-05 aligns the valve channels with common manifold layouts to simplify installation. When the pressure drop across each metering edge equals 5 bar, the valve passes a rated flow of 220 L/min, supporting fast cylinder or motor movement. The maximum operating pressure of 350 bar lets the unit work in high-pressure systems without external pressure relief devices. Pilot oil is taken internally and returned externally, so only the return line needs a separate path back to tank. Continuous service is possible because the duty cycle is 100 %, allowing the solenoid to remain energized without forced cooling pauses. A 24 V DC supply drives the integrated electronics, while the IP65 protection class shields internal components from dust ingress and low-pressure water jets.

The command input of 4–20 mA provides a standardized analog interface for proportional control from PLCs and motion controllers. An identical 4–20 mA actual value output returns the spool position to the host system for closed-loop feedback. Input resistance is 100 Ω, which limits the voltage drop and ensures the current loop remains accurate over long cable runs. Electrical connection is made through a DIN EN 175201-804 connector coded K31, enabling quick exchange during maintenance. Maximum power consumption is 72 VA, so cabinet power supplies can be sized with modest overhead. During dynamic operation the solenoid may draw up to 1.6 A, a level that stays within the limits of standard 24 V control wiring. Coil insulation tolerates temperatures up to 150 °C, preventing thermal degradation during prolonged high-load cycles. The assembled valve weighs 11.2 kg, which affects handling requirements when mounting it on a manifold block.
