PRODUCT OVERVIEW
The pneumatic lug type center line butterfly valve is composed of lug type butterfly valve and pneumatic actuator. The air source drives the valve rod to drive the circular butterfly plate as the opening and closing part, and rotates with the valve rod to open, close and regulate the fluid, so as to realize the requirements of on-site operation and remote centralized control. It is widely used in chemical industry, petroleum, papermaking, fire pipeline, drainage, sewage, food, heating, gas, shipping, hydropower, metallurgy, energy system, light textile and other industries.
PRODUCT FEATURES
1. The valve is small and light, easy to disassemble and repair, and can be installed at any position.
2. The structure is simple and compact, and the 90 ° rotary opening is fast.
3. Small operating torque, labor-saving and light.
4. The flow characteristic of the valve tends to be linear and has good regulation performance.
5. The number of opening and closing tests is up to tens of thousands, and the service life is long.
6. The seal can be replaced, the seal is reliable, the two-way seal is achieved, and the gas test leakage is zero.
7. The sealing material is resistant to aging and corrosion, and can be applied to a variety of media.
