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
