1. Stainless steel pneumatic butterfly valve classified by material: made of stainless steel, with excellent corrosion resistance and high temperature resistance, suitable for a variety of corrosive media and high temperature environments. Carbon steel pneumatic butterfly valve: with carbon steel as the main material, it has high strength and hardness, and is suitable for general industrial fluid control. Pneumatic butterfly valves made of other materials: According to specific needs, pneumatic butterfly valves can also be made of other materials such as cast iron, alloy, etc., to meet the requirements of use under different working conditions.
2. Classification of hard seal pneumatic butterfly valve according to the sealing form: using hard materials such as metal or cemented carbide as the sealing surface, it has high sealing performance and wear resistance, and is suitable for high temperature, high pressure and strong corrosive media. Soft Seal Pneumatic Butterfly Valve: Using rubber, PTFE and other soft materials as the sealing surface, it has excellent sealing performance and low opening and closing torque, and is suitable for general fluid control.
3. Classification of pneumatic clamp butterfly valve according to the structural form: the valve body structure meets the short-distance chuck structure formed due to the narrow pipeline space, the external leakage is zero, and the internal leakage meets the national standard. This butterfly valve is easy to install and is suitable for applications where space is limited. Pneumatic Flange Butterfly Valve: It is composed of a rubber sealed butterfly valve, a carbon steel or stainless steel valve plate and a valve stem, which is connected to the pipeline through a flange connection. This butterfly valve has high sealing performance and stability, and is suitable for various fluid control applications. Pneumatic rubber lining butterfly valve: the connection method includes flange and clamp, and the seal is lined with nitrile rubber, ethylene propylene rubber and other materials to choose from, according to the chemical properties of the medium has a more reasonable choice. This butterfly valve is suitable for corrosive media and applications where high sealing performance is required. Pneumatic fluorine-lined butterfly valve: made of anti-corrosion fluorine-lined material, the valve seat and valve body lining are integrated. This butterfly valve can withstand the corrosion of any medium except molten alkali metal and elemental fluorine, and is suitable for the control of highly corrosive media. Pneumatic Ventilated Butterfly Valve: There is a thin gap between the disc and the seat, which is suitable for environments with poor air circulation. This butterfly valve is mainly used in ventilation systems, air conditioning systems and other fields. In addition, according to specific application scenarios and performance requirements, pneumatic butterfly valves can be further subdivided into pneumatic triple eccentric clamp butterfly valves, pneumatic UPVC butterfly valves, pneumatic quick-assembly butterfly valves, pneumatic expansion butterfly valves and other types.
