WAFER DUAL PLATE CHECK VALVE

Wafer Dual Plate Check Valve Descriptions

Wafer dual plate check valve is one type of check valve with butterfly type disc, which can be mounted on the piping end as exhaust valve. Wafer type dual plate check valve is with two torsion springs added to each of pair valve plates, which close the plates quickly and automatically when the mediums flow back, preventing the medium from flowing back. The wafer butterfly check valve can be mounted onto both horizontal and vertical direction pipelines. We can manufacture the wafer dual plate check valve in accordance with ASME B16.34 and API594.
