FTI offers the full range of check valves from Ham-Lets extensive range.

The H-400 series is a compact designed check valve which provides an accurate operating point. H-400 valves are normally closed. When a differential pressure between inlet and outlet is higher than the set pressure of the spring, the loaded poppet will move backwards and will enable a free passage of flow through the valve..
