D673Y D673Y-10 D673Y-16 Pneumatic butterfly valve

Overview of D673Y D673Y-10 D673Y-16 Pneumatic butterfly valve

D673Y D673Y-10 D673Y-16 Pneumatic butterfly valve  adopts a "U" type stainless steel sealing ring, which is in three-dimensional eccentric contact with the polished butterfly plate. The utility model solves the disadvantage that the sealing surface of the traditional eccentric butterfly valve is still in sliding contact friction at the moment of opening and closing 0 ° ~ 10 °, realizes the effect that the sealing surface of the butterfly plate is separated at the moment of opening, and the sealing effect is achieved at the moment of closing contact, so as to prolong the service life and improve the sealing performance. Therefore, it is widely used in pipelines with corrosive media such as metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas and water supply and drainage with medium temperature ≤ 550 ℃. It is a good device for regulating flow and cutting off fluid.

Features of D673Y D673Y-10 D673Y-16 Pneumatic butterfly valve

1. The three eccentric sealing structure is adopted, and the valve seat and butterfly plate are almost free of wear, which has the sealing function of tighter and tighter

2. The sealing ring is made of stainless steel, which has the dual advantages of metal hard seal and elastic seal. It has excellent sealing performance, corrosion resistance and long service life under the conditions of low and high temperature

3. The sealing surface of butterfly plate adopts surfacing cobalt based cemented carbide, which is wear-resistant and has long service life

4. The large-size butterfly plate adopts the frame structure, with high strength, large overflow area and small flow resistance

5. The wafer type hard seal butterfly valve has the function of two-way sealing. It can be installed in any direction without the restriction of medium flow direction and the influence of space position
