Product Description

Electric Ventilation Butterfly Valve (GAD941W)

Product Description

The ventilation butterfly valve is made of steel plate welding and has the characteristics of short structural size, light weight, and convenient installation. The valve has small driving torque, flexible opening and closing, and convenient operation. An oil seal retaining ring is installed on the valve body, and there is no visible gap between the sealing pairs, resulting in a low leakage rate. The expansion gap between the butterfly plate and the valve body is large, which can effectively prevent jamming caused by thermal expansion and contraction. This valve can be equipped with various driving devices, such as manual devices, worm gear transmission devices, pneumatic devices, and electric devices. Ventilation butterfly valves are widely used in industrial pipelines such as metallurgy, chemical engineering, power, building materials, mines, etc., and have the function of controlling or regulating medium gas.
