Structural characteristics and uses: 

 This series of butterfly valve is in the absorption of foreign advanced technology, based on the user's actual working conditions under which a new generation of quick disconnect valve design. Characterized by (1) the use of rubber seals, seal performance, no leakage; (2) The double eccentric conical seal structure, the use of larger organizations and more tightly sealed automatically compensate for wear of sealing function: (3) dual role cylinder drive, opening and closing torque, movement speed, the valve open and close rapidly, flow resistance loss. (4) cylinder with buffer design, improving the service life; cylinder is equipped with a muffler to reduce noise pollution to the environment. For blast furnace gas, converter gas and other combustible gas pipeline quickly cut off the occasion required.
