The pneumatic butterfly valve consists of a pneumatic actuator and butterfly valve. A pneumatic butterfly valve is a kind of pneumatic valve with opening and closing characteristics. The circular butterfly plate realizes the opening and closing action by rotating the valve stem. It is mainly used as a shut-off valve. It can also be designed with regulating valve or segment valve and regulating function. Butterfly valves are increasingly used in low-pressure large and medium-sized pipelines. Classification of pneumatic butterfly valves: stainless steel pneumatic butterfly valve, hard seal pneumatic butterfly valve, soft seal pneumatic butterfly valve, carbon steel pneumatic butterfly valve. The main advantages of pneumatic butterfly valves are simple structure, small size, lightweight, and low cost. The characteristics of pneumatic butterfly valves are particularly significant. Installed in high-altitude concealed passages, it is controlled by a two-position five-way solenoid valve. The operation is simple, and the medium flow can also be adjusted.
Pneumatic butterfly valve and anti-corrosion butterfly valve adopt two-piece valve body combination, valve seat and valve body lining are integrated. When the valve is working, only the all-plastic valve seat and the plastic-lined butterfly plate are in contact with the medium, and the product can withstand the corrosion of any medium except molten alkali metal and elemental fluorine. Among them, the d71f46 valve stem is integrated with the butterfly plate (forging), and the surface is evenly coated with a layer of FEP. The surface of the valve body is smooth, the fluid resistance is small, the CV value is high, the circulation capacity is strong, and the torque is moderate. The four-stage sealing structure is adopted, and the high-temperature and aging-resistant silicone rubber elastic pad is set outside the sealing surface, which completely realizes zero leakage of the medium. Pneumatic ventilation butterfly valve, features: There is a small gap between the valve plate and the valve seat. This product is suitable for environments with poor air circulation. The main features of the pneumatic butterfly valve are: novel and reasonable design, unique structure, light weight, convenient operation, and rapid opening and closing; in addition to the functions of regulating and intercepting flow, and compensating the thermal expansion and cold contraction caused by the temperature difference of the pipeline, the telescopic butterfly valve can also be used for the valve. Easy installation, replacement, and maintenance. The seals are adjustable and replaceable, and the sealing performance is reliable.
