Henan Yuda valve ventilation butterfly valve manufacturer, ventilation butterfly valve using the same material as the valve body processed into a seal, its applicable temperature with the valve body selection, nominal pressure is ≤0.6Mpa, generally applicable to industrial, metallurgical, environmental protection and other pipelines for ventilation to regulate the flow of media.
Ventilation butterfly valve is divided into manual and electric drive, which can be driven by electric motor or turbine to drive the actuator and make the butterfly plate rotate freely within 90 degrees for the purpose of opening and closing or regulating the flow of medium. The structure of ventilation butterfly valve is welded by using midline butterfly plate and short structural steel plate, so it has no internal components such as connecting rod and bolt, so it will not produce some component problems in the process of use, so the failure rate is very low and easy to use, and 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.
