Pneumatic soft-sealed wear-resistant butterfly valve

The  pneumatic  soft-sealed wear-resistant butterfly valve consists of a rubber-sealed butterfly valve and a valve plate made of carbon steel or stainless steel, along with a valve stem. It is suitable for temperature ≤120°C and is used in water supply and drainage, gas pipelines in industries such as food, pharmaceuticals, chemicals, petroleum, power, light industry, textiles, and papermaking to regulate flow and block media. The main advantages of the Pneumatic Butterfly Valve include a simple structure, compact size, lightweight, and low cost, with these features being particularly notable. When installed in elevated or concealed pipelines, it can be conveniently operated via a two-position five-port solenoid valve and also regulate the flow of media.
The pneumatic soft-sealed wear-resistant butterfly valve consists of a pneumatic actuator and a butterfly valve. The Pneumatic Butterfly Valve uses a circular disc that rotates with the valve stem to achieve opening and closing, primarily serving as a shut-off valve but can also be designed with regulating or throttling functions. Currently, butterfly valves are increasingly used in low-pressure pipelines with medium to large diameters. The advantages of Pneumatic Butterfly Valves mainly include a simple structure, compact size, lightweight, and low cost, with these features being particularly notable. When installed in elevated or concealed ducts, pneumatic butterfly valves are controlled via a two-position, three-way (or two-position, five-way) solenoid valve, offering convenient operation and the ability to regulate flow media.
