The Hydac WSM06020 is a high-performance, direct-acting 2/2-way solenoid poppet valve designed as a screw-in cartridge. It is engineered for reliable blocking and load-holding applications in hydraulic systems. In its de-energized state, the valve is normally closed, preventing flow from port 1 to 2, while allowing free flow from 2 to 1. When the solenoid is energized, the poppet opens, permitting flow from 1 to 2. Its robust construction and poppet design ensure minimal leakage and a long service life, making it an ideal choice for mobile and industrial hydraulic circuits requiring precise control and high pressure tolerance.
