Product Details

Wafer Tilting Disc Type Check Valve

H77  check valve is a flanged non-impact check valve with flange size of ASME  B16.5 GB HG SH. Its main advantage is to overcome the impact and water hammer phenomenon caused by the rotary check valve and the lifting upreturn valve under the working condition, and to realize the non-impact operation. 

Wafer Tilting Disc Type Check Valve

Design feature
