3.complete sealing,no leakage of water when pressure-testing.

Application：

The wafer check valve with double discs is light with a small body,but a kind of check valve that quickly develops,which functions to preventing media in pipes from backflowing.mainly used on those pipes in which media flow unidirectionally and to control the media to flow only one-way so as to prevent accident.
