Papua New Guinea Handle type ventilation butterfly valve
Product Description
Handle type ventilation butterfly valve is widely used, this kind of valve is durable basically is zero fault, the valve is free to slide flexible, has the characteristics of excellent sealing performance, the use of the process of local resistance loss is small, good regulation, so it is widely used. The nominal pressure of manual flapper valve is 0.05Mpa, applicable temperature: ≤ 200 ℃, applicable medium: grain, granule, powder material, etc. Kailong environmental protection new ventilation butterfly valve set all the advantages in one, to overcome the old-fashioned ventilation butterfly valve leakage, deformation, adjustment difficulties and other drawbacks, the use of easier and more convenient.
Handle type ventilation butterfly valve
The handle flange ventilation butterfly valve is made of steel plate welding, which has the characteristics of short structure size, light weight and convenient installation. The valve drive torque is small, open and close flexible, easy to operate. The valve body is provided with an oil seal retaining ring, no visible gap between the sealing pairs, and the leakage rate is small.
The expansion gap between the butterfly plate and the valve body is large, which can effectively prevent the sticking phenomenon caused by thermal expansion and contraction. The valve can be equipped with a variety of driving devices, such as manual devices, worm gear, pneumatic devices, electric devices. Ventilation butterfly valve is widely used in metallurgy, Shihua, electric power, building materials, mining and other industrial pipelines to control or regulate the medium gas.
Manual ventilation butterfly valve is a commonly used device for dust collector equipment. The valve body and valve plate in the valve are welded with high-quality carbon steel plates. Manual ventilation butterfly valve, also known as manual air door, flue air valve, round air door, etc., is a sealed rotary valve. Manual ventilation butterfly valve is widely used, especially the handle type ventilation butterfly valve. It has simple structure, small flow resistance, and light weight., Flexible rotation, long service life, convenient operation and maintenance, etc., is a widely used environmentally friendly product.
