The Winner EC04W is a high-performance, pilot-operated check valve designed in a screw-in cartridge style. This valve allows free flow from the valve port (port 2) to the load port (port 1) while blocking flow in the opposite direction. Applying sufficient pressure to the pilot port (port 3) will unseat the check poppet, allowing flow from port 1 to port 2. Its robust design makes it ideal for load-holding applications, preventing actuator drift and ensuring system stability and safety. The EC04W is engineered for insertion into a standard C-04-2 cavity, providing a compact and reliable solution for various hydraulic circuits.
