Operation method The valve clack is automatically opened and closed under the medium force to prevent flowing to another direction.
Application fields For application in fields such as electric power industry, petroleum refining, petrochemical engineering, offshore oil, tap water engineering in urban construction, chemical engineering, etc.
Other remarks 1 The sealing faces of valve seat and valve clack are build-up welded with hard alloy to improve the erosion resistance and extend the service life of valve.
Other remarks 2 Short closing travel of valve clack, and small impact at valve closing; short structural length, most suitable for positions with limited mounting space
Other remarks 3 Suitable for medium backflow prevention in pipeline or device
Other remarks 4 Built-in pin roll, without external leakage point
Other remarks 5 Due to loading of spring, the valve clack can move flexibly without jamming, and has a good sealing performance.
