Stainless steel swing check valve installation position is not restricted, usually installed in the horizontal pipeline, but can also be installed in the vertical pipeline or dumping pipeline. Swing check valve valve flap around the rotary axis for rotary movement, its fluid resistance is generally smaller than the lift check valve, it is suitable for larger caliber occasions. Widely used in petroleum, chemical, pharmaceutical, electric power industry and other working conditions of the pipeline.

Stainless steel rotary check valve according to the number of valve flap can be divided into single flap rotary, double flap rotary and multi-flap rotary three kinds. Single flap rotary check valve is generally applicable to medium caliber occasions, large caliber pipeline selection of single flap rotary check valve. In order to reduce water hammer pressure, the use of slow closing check valve can reduce water hammer pressure; double valve swing check valve for large and medium caliber pipeline, clamp double valve swing check valve structure is small, light weight, is a fast development of the check valve; multi-valve swing check valve for large caliber pipeline.

Stainless steel rotary check valve product structure is compact and reasonable, reliable sealing, reliable performance, small size, light weight, wide range of applications, the valve flap closes quickly, sensitive action, the closing impact is small, not easy to produce water hammer phenomenon, the flow path is smooth, fluid resistance is small.
