Sanitary Butterfly Valve Stainless Steel Powder Butterfly Valve Butterfly
1. Introduction
Butterfly valve is a simple structure of the regulating valve, but also can be used for low-pressure pipeline media switching control. Ventilation butterfly valve is a kind of non-closed type butterfly valve. Main products: large ventilation butterfly valve, electric ventilation butterfly valve, leakage rate of 0, explosion-proof ventilation butterfly valve.
2. Specification
The structure of the ventilation butterfly valve is welded using a centerline butterfly plate and a short structural steel plate, so it has no internal components such as connecting rods and bolts, and there will not be 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, but the service life is longer than the elastic seal, and has the characteristics of high temperature resistance. So it has a wide range of applications in building materials, electric power, metallurgy and other industries. In the temperature is not higher than 300 degrees in the medium transportation pipeline, can realize the connection and shutdown regulation role. This kind of butterfly valve can also be specially customized according to the needs of customers, very humanized.
