Wafer Type Check Valve Ductile Iron Body＆Disc

Wafer Type Check Valve

1. PRODUCT PROFILE

Wafer type dual plate check valve is one type of non-return valve with two torsion springs added to each of pair valve plates, which close the plates quickly and automatically, preventing the mediums from flowing back. Wafer dual plate check valve can be mounted between the two pipes in both horizontal and vertical directions. The wafer type check valves are wafer-type valves with a short overall building length. Their excellent hydrodynamic properties lead to very low pressure losses.The lower weight of the dual-plate check valves brings advantages during installation, transport and storage.With the suitable springs, the dual-plate check valves can be installed in any position.
