The 4WRL16V1-200M-3X/G24K0/M-750 is a proportional solenoid valve from Bosch Rexroth in the 4WRL Solenoid Valves series. It meters hydraulic flow for industrial automation circuits that require progressive spool control. The NG16 size establishes a porting interface suited for medium flow manifolds, while the ISO 4401-07-06-0-94 mounting pattern aligns the body with standardized subplates. Electrical actuation operates on a 24 V DC supply; the coil presents a resistance of 2.5 Ω at 20 °C so that inrush and steady-state power are predictable. During command steps the solenoid may draw up to 2.7 A, delivered through a DIN 43650 / ISO 4400 connector that simplifies field wiring. An IP65 degree of protection shields internal components from dust and low-pressure water jets. The spool marked with symbol V1 provides a progressive flow characteristic M, allowing the valve to pass 200 l/min at a 10 bar differential without sudden jumps in velocity.
For circuit integration, pilot oil is supplied externally through port X and returned externally by port Y, which isolates pilot pressure from the main flow and prevents load-induced oscillations. Working ports P, A, and B tolerate continuous pressures up to 350 bar, while ports T, X, and Y are limited to 250 bar to protect the tank and pilot lines. The stable pilot circuit can be maintained with a small auxiliary pump, allowing consistent spool positioning even when system pressure fluctuates. The valve is intended for mineral oil in the HL or HLP grades, and NBR sealing elements prevent leakage when these fluids are used. Together, the fluid compatibility, pressure ratings, and external pilot layout provide reliable proportional control for presses, test benches, and closed-loop positioning axes across a broad temperature and duty range.
