4WRL16W1Z180S-3X/G24EZ4/M

The 4WRL16W1Z180S-3X/G24EZ4/M solenoid valve is produced by Bosch Rexroth as part of the 4WRL Solenoid Valves series. It meters hydraulic flow in automated systems by shifting a spool with an energized coil. The valve operates with a 24 V DC supply voltage, and the coil draws up to 2.7 A so control electronics must deliver that current. During steady energization, electrical demand stays within 40 VA which simplifies power budgeting in multi-axis manifolds. The coil has a cold resistance of 2.5 Ω, allowing technicians to verify integrity with an ohmmeter. Command changes translate into motion quickly; the response time from 0 to 100 percent stroke is 40 ms at 100 bar, enabling closed-loop pressure control. Magnetic hysteresis does not exceed 0.1 percent, so the spool returns to the same position after cyclic actuations. The body mounts to sub-plates conforming to ISO 4401-07-06-0-94, ensuring interchangeability with standard CETOP size 07 patterns. Shipping mass is 10 kg, a value relevant for handling and support bracket design.

The hydraulic section passes a maximum flow of 450 l/min, giving adequate capacity for medium-size actuators and presses. Working ports A and B tolerate continuous operating pressure up to 350 bar, while drain, pilot, and tank ports t, X, and Y are limited to 250 bar to protect seals and internal passages. Pilot stages function between 10 bar minimum and 250 bar maximum, permitting reliable spool positioning across common system pressures. Continuous energization is permissible because the valve is rated for a 100 percent relative duty cycle, preventing thermal overload during long control sequences. An IP65 protection class keeps dust ingress and water jets from affecting the coil when the mating connector is installed correctly. Flow paths are sealed with NBR material, matching mineral oil compatibility in industrial circuits. Together these limits and materials confirm that the valve can sustain high-duty proportional control without external enclosures.
