The 4WRZE16W6-150-7X/6EG24N9EK31/F1V valve is produced by Bosch Rexroth in the WRZ Proportional Directional Valves series. It meters hydraulic flow and direction in closed-loop automation circuits. The valve is supplied in size 16 to match medium-flow manifolds. Subplate mounting is required, and the interface follows ISO 4401-07-06-0-94 so it fits standard pattern blocks. When a 10 bar pressure drop exists, the spool passes 150 l/min, ensuring adequate actuator speed. The hydraulic sections withstand operating pressures up to 350 bar for use on high-pressure lines. The coil is energized from a 24 V DC source; under steady state it draws up to 1.8 A, while a 3 A pulse current is permitted during control transitions to accelerate spool movement.
Command value overlap is held to 15 %, providing predictable dead-band during small signal changes. The solenoid can run continuously because the duty cycle is 100 %. Electrical connection is made through a DIN EN 175201-804 plug, allowing quick field replacement. Winding resistance is 2 Ω at 20 °C, and copper temperature may rise to 150 °C without damage. An IP65 housing shields the coil against dust and water jets, while FKM seals protect the hydraulic path from fluid leakage and chemical attack. Total mass is 13.6 kg, which gives the assembly enough inertia to resist vibration once bolted to the subplate.
