The HYDAC WSM08130D is a high-performance, direct-acting 3/2-way solenoid-operated directional spool valve. Designed as a screw-in cartridge valve, it is used to control the start, stop, and direction of fluid flow within a hydraulic system. This ‘D’ model is a normally-open valve, meaning that when the solenoid is de-energized, flow is permitted from port 2 to port 3, while port 1 is blocked. Energizing the solenoid shifts the spool to allow flow from port 1 to port 2. It features a wet-pin DC solenoid for efficient heat dissipation and long service life. The robust construction ensures reliable operation in demanding industrial and mobile hydraulic applications.
