Do you know what is a ventilation butterfly valve?

Ventilation tools of different periods are related to the development of scientific and technological productivity. When modern industry began to put the main force of ventilation on ventilation butterfly valve, it can be found that ventilation butterfly valve is really a good tool. Just as we find the law from different types and styles of ventilation butterfly valves, we can also find the practical application form of the whole ventilation butterfly valve from the process of ventilation.

When the manual ventilation butterfly valve is in the fully open position, the thickness of the manual ventilation butterfly plate is the only resistance of the medium flowing through the valve body, so the pressure drop generated by the valve is very small and therefore has good flow control characteristics. Butterfly valves have resilient seal and metal seal. With resilient seal valves, the seal can be embedded in the valve body or attached to the butterfly plate.

 

Material and classification

Our company specializes in producing various specifications of ventilation butterfly valves in carbon steel, manganese steel, stainless steel and heat-resistant steel.

Ventilation butterfly valves are divided into manual, electric and pneumatic actuators. The actuator can be driven by electric motor or turbine to make the disc rotate freely within 90° for the purpose of opening and closing or regulating the flow of medium.
