The Pneumatic Dust Butterfly Valve and the anti-corrosion butterfly valve adopt a two-piece valve body combination, and the valve seat and the valve body lining are integrated. When the valve is working, only the full 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 ability is strong, and the torque is moderate. Four-stage sealing structure is adopted, and high-temperature-resistant and aging-resistant silicone rubber elastic pads are set outside the sealing surface to completely realize 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 use in 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 quick opening and closing; the telescopic butterfly valve not only has the functions of regulating and shutting off, compensating for thermal expansion and cold contraction caused by temperature differences in pipelines, but also can be used for valves. Easy installation, replacement and maintenance. The seal is adjustable and replaceable, and the sealing performance is reliable.
