304ss butterfly damper valve

Manual, electric, pneumatic series of 304SS Butterfly Damper Valve are made of steel plate welding, with the characteristics of short structure size, light weight and convenient installation. The 304SS Butterfly Damper Valve has small driving torque, flexible opening and closing, and convenient operation. There is no visible gap between the sealing pairs and the leakage rate is small. The expansion gap between butterfly plate and valve body is large, which can effectively prevent the jamming caused by heat expansion and cold contraction. The 304SS Butterfly Damper Valve can be equipped with a variety of driving devices, such as manual device, worm gear transmission device, pneumatic device, electric device. Ventilation butterfly valve is widely used in metallurgy, petrochemical, electric power, building materials, mining and other industrial pipelines, to control or regulate medium gas
