I plant production of ventilation butterfly valve USES the steel plate welding, a short structure size, light weight, easy installation, etc. The valve drive torque is small, easy, easy to operate. Body set on oil seal ring, no visible gap between seal, leakage rate is small. Between the butterfly plate and the valve body expansion gap is big, can effectively prevent card deaths caused by heat from the cold. This valve can be equipped with a variety of device drivers, such as manual gear, worm gear drive, pneumatic device and electric device. Ventilation butterfly valve is widely used in metallurgical, chemical, electric power, building materials, mining and other industrial pipelines, on medium gas gas control or adjustment.

USES and features:

Electric shutter type butterfly valve with electric actuators are widely used in building material, metallurgy, mining, power, such as the production process, automatic control or manual control medium flow in pipe. Butterfly plate the shutter multiaxial structure, uniform liquid, open-close torque is small, action quick, reliable in performance.
