The HYDAC WSM08130C-01 is a direct-acting solenoid operated 3/2-way directional spool valve. Designed as a screw-in cartridge valve, it fits into standardized cavities for easy integration into hydraulic manifold blocks. This model is typically configured as normally closed (NC), blocking port 2 in the de-energized state and allowing flow from port 1 to port 3 when the solenoid is energized. It is commonly used for controlling the direction of flow in various mobile and industrial hydraulic applications.
