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.
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.
1. Small operating torque, easy to operate, labor-saving and intelligent.
2. Novel design, reasonable, unique structure, light weight, quick opening and closing.
3. No connecting rod, bolt, etc., reliable operation and long service life. Can be installed in multiple workstations.
4. Select suitable materials to meet the low, medium and dielectric temperature and corrosive media.
5. Designed and manufactured with new structure form of welded centerline butterfly plate and short structure steel plate, compact structure, light weight, easy installation, small flow resistance, large circulation capacity, avoiding the influence of high temperature expansion.
Ventilation butterfly valve has simple structure, superior performance, high temperature resistance and corrosion resistance, it is a kind of regulating butterfly valve, and can also be used for switching control of low pressure pipeline medium.
Ventilation butterfly valve is used for dusty cold air or hot air gas pipeline of ventilation and environmental protection projects in chemical, building materials, power station, glass and other industries. It is used as a control device to regulate the flow of gas medium or cut off the pipeline. This type of valve should generally be installed horizontally in the pipeline.
