TD941W electric ventilation butterfly valve
Product number:TD941W
product description:

  The ventilation butterfly valve produced by our factory is made of steel plate welding, which has the characteristics of short structure size, light weight and convenient installation.The valve has a small driving torque, flexible opening and closing, and convenient operation.An oil seal retaining ring is set on the valve body, there is no visible gap between the seal pairs, and the leakage rate is small.The large expansion gap between the butterfly plate and the valve body can effectively prevent the jam caused by thermal expansion and contraction.The valve can be equipped with a variety of driving devices, such as manual devices, worm gears, pneumatic devices, and electric devices.Ventilation butterfly valves are widely used in industrial pipelines such as metallurgy, normalization, electric power, building materials, mining, etc., to control or regulate medium gas.
