The EATON SM4-20(15)57-80/40-10-S182 / 3025047 is a heavy-duty industrial proportional valve engineered for precise electrohydraulic flow and pressure control in demanding hydraulic circuits. As part of the Vickers proportional valve series, it provides infinitely variable actuation via a wet-pin proportional solenoid, delivering smooth, responsive modulation without the complexity of servo-level filtration requirements.
