Ventilation Butterfly Valve

Ventilation Butterfly Valve

Uses：Widely used in various services and drains, building fire protection, etc., especially fire protection pipes.

Size: various

Media: water, steam, oil, strong alkali, etc.

Supplier: Factory direct sales

Application: for large diameter (LV) air, gas pipelines, roads and waterways.

The structure of the ventilation butterfly valve manufactured by Zhejiang Huachi Valve Co., Ltd. is welded using a midline butterfly plate and a short structural steel plate, so it has no internal components such as connecting rods and bolts, which will not create some component problems in the process of use, so the failure rate is very low. It is easy to use. It is a reliable valve device. And because its sealing system uses metal closure, although the sealing effect is not as good as the elastic seal, the service life is longer than the elastic seal, and it has the characteristics of high temperature resistance. So it has wide application in building materials, electric power, metallurgy and other industries. In the temperature is not higher than 300 degrees in the medium transmission pipeline, can realize the connection and close the adjustment role. This kind of butterfly valve can also be specially customized according to the needs of customers, which is very humanized.

Because the gap between the butterfly plate and the valve body of the ventilation butterfly valve is large, there is enough expansion space, so it can effectively prevent the thermal expansion and contraction brought about by temperature changes in the process of use, and the butterfly plate will not produce the phenomenon of jamming. The common butterfly valve has a variety of driving methods, including manually driven, electrically driven, and pneumatically driven, etc. There is a wide range of options. Because of the material, this butterfly valve also has high temperature resistance, and there is no friction when opening and closing, so the service life is extremely long. Ventilation butterfly valve is a kind of valve made of welded steel plate, it has the characteristics of small size and light weight, easy to install, and because of its small flow resistance, the flow volume is large and will not be affected by high temperature expansion. It is easy to operate because it has a small driving torque and is very flexible to open and close. It is well liked by the industry.
