We are a large valve manufacturer with global headquarters in Wenzhou, China, integrating design, production and sales, and able to provide you with comprehensive services and professional support. This valve can be used in a variety of industries, including but not limited to steel, electricity, petroleum, drainage engineering, etc.
Pneumatic flanged metal seated butterfly valve is a valve that is very sophisticated from raw material selection to design and manufacturing. It is an energy-saving valve with a relatively long service life. The valve is composed of main components such as valve body, butterfly plate, sealing ring, transmission mechanism, etc. It adopts two-dimensional or three-dimensional eccentric principle design and applies new processing technology such as elastic sealing or hard and soft multi-layer sealing.
In terms of performance, this butterfly valve has small operating torque, corrosion resistance, high temperature resistance, wear resistance, adaptability to different types of media, overall reliable performance, more efficient and convenient.

Performance Features
1. Pneumatic flanged metal seated butterfly valve is relatively small and light, flexible and labor-saving to operate.
2. The valve is strictly implemented in accordance with various standards, striving for reliable sealing performance.
3. In the main functional performance, the flow characteristics are good, ensuring the main adjustment function.
4. The eccentric principle is applied to the design, and the sealing surface is almost zero wear.
5. It has a wide range of applications and can be used in different industries. It can adapt to pipelines of various working conditions such as different temperatures, grades, and corrosion. The main media that can be used include water, steam, oil, air, gas, etc.
6. The valve body and valve seat of the valve are connecting parts, and the sealing surface layer is made of surfacing heat-resistant and corrosion-resistant alloy material.
7. Regarding the three-eccentric principle in the valve, the center line of the shaft deviates from the center line of the sealing surface, the center line of the shaft slightly deviates from the center line of the pipeline, and the center line of the valve body sealing surface (oblique cone) forms an angle with the center line of the pipeline.
8. There are multiple layers of sealing rings fixed on the valve plate, which are tolerant to high temperatures and have no friction when opening and closing. When closed, as the torque of the transmission mechanism increases, the seal is compensated. The application of soft and hard laminated metal sheets can also ensure that the valve sealing is not affected by temperature and environmental changes.
