Dual plate swing check valve features

Two valve plates are fixed on the valve body along a pivot
The two springs are installed on the butterfly plate above the sealing surface.
Pushed by the medium flow pressure, the spring is compressed, forcing the butterfly plate to open.
When the medium flows backwards, the spring forces the valve to close.
Good sealing performance
Small size and light weight
Wide range of applications
Valve plate closes quickly
Small closing impact
Both horizontal and vertical pipelines can be used, easy to install
Smooth flow channel, fluid resistance is small
Sensitive action and good sealing performance
The overall structureis simple and compact, beautiful appearance
Long service lifetimeand high reliability
