The TRIPLE OFFSET design of the TRIPLE OFFSET butterfly valve has the characteristics of sturdy structure, zero leakage closing capacity, low operating torque, and actual zero sealing surface wear. The sealing structure of triple eccentric butterfly valves usually includes multi-level sealing rings, U-shaped elastic sealing rings, and pure metal to metal seat sealing ring designs, which enable the valve to operate under various harsh working media, working pressure, and working temperature conditions.

The configuration of multi-level metal hard seal butterfly valve design can resist the corrosion of various chemical solvents, especially suitable for pipeline transportation control of particle slurry and chemical media. There are rubber flanges at both ends of the hose, which do not require additional gaskets when connecting the valve to the pipeline. The valve channel and control medium space are completely isolated, without inside and outside. By flowing fluid in the elastic hose, the crystallization of the fluid can be eliminated, If the rubber sleeve of a multi-level hard sealed butterfly valve design is found to be damaged, its structure can achieve rapid replacement and maintenance of the rubber sleeve. The multi-level hard sealed butterfly valve is designed scientifically, with high wear resistance and corrosion resistance. It can withstand various medium concentration acids and alkaline salt solutions of any concentration, such as pulp, dry and wet powders, and crystals. Different media are equipped with hoses with different rubber formulas, which can meet the production needs of users. When using multi-level hard sealed butterfly valves at low temperatures, please use a dryer to handle the dry air. When piping, thoroughly remove impurities, debris, etc. from the piping and joints. The structure is novel and simple
