Product overview

The pneumatic lug type butterfly valve is composed of two parts: lug type butterfly valve and pneumatic actuator. The air source drives the valve stem to drive the circular butterfly plate as the opening and closing part and rotates with the valve stem to open, close and adjust the fluid, so as to realize the requirements of on-site and remote centralized control. It is widely used in chemical, petroleum, paper, fire pipes, drainage, sewage, food, heating, gas, shipbuilding, hydropower, metallurgy, energy systems and textile and other industries.



Product characteristics
1, the valve is small and light, easy to disassemble and repair, and can be installed in any position.
2, simple structure, compact, 90° turn open quickly.
3. Small operating torque, labor-saving and light.
4, the valve flow characteristics tend to be straight, good adjustment performance.
5, the number of opening and closing tests up to tens of thousands of times, long life.
6, the seal can be replaced, the seal is reliable to achieve two-way sealing, and the gas test leakage is zero.
7, sealing material aging resistance, corrosion resistance, can be applied to a variety of media.
