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
