The metal sealing butterfly valve with two-way flow resistance coefficient is small, open and close quickly, light weight, corrosion resistance, high temperature, long service life, widely used in the sealing function of the complex dual-flow piping system; and all the parts materials and coatings used are non-toxic environmentally friendly design, especially for water pipe network construction industry.
Reverse valve for ordinary work, sealing the defects can not be achieved, the valve is sealing ring deformation compensation structure, so that sealed the loss of part of the compensation than the pressure to ensure the valve under flow in any direction can achieve close relations off. Two-way valve worm gear display, user operating very convenient.

The two-metal seal butterfly valve has a flow resistance coefficient of small, rapidly headstock, light weight, corrosion resistance, high temperature resistance, long life and other characteristics, widely used in sealing function required double the flow of the complexity of the piping system; and all parts and materials and coatings selection are non-toxic environmentally friendly design, is particularly applicable to tap water pipe network engineering industries.
Reverse butterfly valve for ordinary work, not sealed defects, the use of the valve ring deformation compensation structure, so that part of the loss of sealed pressure compensation, ensure that the valve flow in any direction at all under the strict implementation of the customs off. Valve worm gear with a two-way display, the user is very convenient to operate
