This product is a new type of valve developed by our company, which has the advantages of quick installation, simple and reliable, light weight, flexible operation and easy maintenance. In particular, it has both the good sealing characteristic of eccentric butterfly valves and the fast connection required by pipe fittings. It can be widely used in water supply and drainage, fire, petroleum, chemical, medicine, steel, etc., using the new domestic trench pipe fitting pipe as a cut-off or adjustment.
