The ventilating butterfly valve is a valve that uses a circular disc as a starting and closing member and rotates with the valve stem to open, close and adjust the fluid passage of the high temperature butterfly valve. The ventilation butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, easy to operate and fast, and also has good flow regulating function and closed sealing characteristics, in large and medium caliber, In the field of low and medium pressure, stainless steel butterfly valves are the dominant valve form.
The manual ventilation butterfly valve is welded by high-quality steel plate, the structure is simple, the weight is light, and the electric moving ball valve is convenient to use and maintain. The manual ventilation butterfly valve is non-sealed and used to regulate the flow of the medium. It is widely used in the ventilation, dust removal, environmental protection and heating and ventilation of metallurgy, mining, chemical, building materials, power stations and other industries. It can be equipped with pneumatic, electric and other actuators.
Ventilation butterfly valve use and characteristics
The ventilation butterfly valve is processed into a sealing ring with the same material as the valve body. The applicable temperature depends on the material selection of the valve body. The nominal pressure is ≤0.6MPa, which is generally suitable for industrial, metallurgical, environmental protection and other pipelines for ventilation and regulating medium flow.
The main features of the ventilation butterfly valve are:
1. The design is novel, reasonable, unique in structure, light in weight, and quick to open and close.
2, the operating torque is small, easy to operate, labor-saving and smart.
3. Use suitable materials to meet low, medium and high dielectric temperatures and corrosive media.
