Dual plate swing check valvefeatures
Two valve plates are fixed on the valve body along a pivotThe 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 performanceSmall size and light weightWide range of applicationsValve plate closes quicklySmall closing impactBoth horizontal and vertical pipelines can be used, easy to installSmooth flow channel, fluid resistance is smallSensitive action and good sealing performanceThe overall structureis simple and compact, beautiful appearanceLong service lifetimeand high reliability
