Pneumatic lug type butterfly valve
Product parameters
Pneumatic lug type butterfly valve is composed of pneumatic actuator and butterfly valve. Pneumatic butterfly valve is a pneumatic valve that uses a circular butterfly plate that rotates with the stem to achieve activation. It is mainly used as a cut-off valve. It can also be designed to have the function of adjustment or segment valve. The use of medium-diameter pipes is increasing. Pneumatic butterfly valve classification: stainless steel pneumatic butterfly valve, metal seal pneumatic butterfly valve, soft seal pneumatic butterfly valve, carbon steel pneumatic butterfly valve. The main advantages of pneumatic butterfly valve are simple structure, small size, light weight and low cost. This feature of pneumatic butterfly valve is especially remarkable. It is installed in a dark tunnel at high altitude and is controlled by a two-position five-way solenoid valve. It is easy to operate and can also adjust the flow medium.

Advantages
1. Small opening torque, flexible and convenient, labor-saving and energy-saving.
2. The structure makes the butterfly plate close tighter and tighter, and its sealing performance is reliable and leak-free.
3. High pressure resistance, corrosion resistance, wear resistance, long service life, etc.
Features
Valve body was from our own casting factory. The valve plate and sealing ring adopt a unique structure, which has the characteristics of compact structure, small volume, light weight, good cutting performance and long service life, and is easy to maintain and repair. It is widely used in chemical, electric power, textile, food, medicine and other industrial sectors, as well as in municipal engineering, water plants and other pipelines to cut off or adjust the flow of tap water, sewage or air, gas, natural gas media.
