                  product description

                  Product features

                  1, the valve adopts three eccentric sealing structure, the seat and disc almost no wear, with more view more tight sealing function.

                  2, the seal ring is made of stainless steel, with metal hard seal and elastic seal double advantages, no matter in the case of low temperature and high temperature, have excellent sealing performance, corrosion resistance, long service life and other characteristics.

                  3, plate sealing surface using surfacing welding cobalt base hard alloy, sealing surface wear resistance, long service life.

                  4, large size butterfly board adopts quilted structure, high strength, large flow area, small flow resistance.

                  5, the valve has a two-way sealing function, installation is not limited by the flow of media, also not affected by the space position, can be installed in any direction.
