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
