WM Directional Spool Valves

Bosch Rexroth WM Directional Spool Valves are direct operated directional valves used within hydraulic systems. They are available in 4/3, 4/2, or 3/2 directional designs and are built to conform to standards like ISO 4401. The valves work by using an internal spool that is shifted to connect or block different ports within the valve housing, thus determining the path of the hydraulic fluid. This spool movement is actuated by various mechanical or manual means, such as a hand lever, rotary knob, or roller plunger. Their essential function is to reliably control the direction of fluid flow to hydraulic actuators, operating with a maximum pressure up to 350 bar.
