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 hours of 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 specific pressure compensation, ensure that the valve under flow in any direction can achieve close relations off. Two-way valve worm gear display, user operating very convenient.
