product description:
The PTFE butterfly valve is to meet the needs of some special fields such as petroleum, chemical industry, food and so on in some corrosive environments with strong acid and strong alkali. The valve body made of PTFE has a strong anti-corrosion effect. Under normal conditions, it can replace the stainless steel valve body and has a higher cost performance. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation reaches 90°, the valve is in a fully open state.
The butterfly plate of the pneumatic wafer butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis. The initial position of the valve is determined according to actual requirements. When the valve rotates 90° from the initial position, an action ends (from opening to closing, or by Close to open), otherwise, another action (from close to open, or from open to closed) ends.
Features:
1. Novel and reasonable design, unique structure, light weight, and rapid opening and closing.
2. Small operating torque, convenient operation, labor-saving and smart.
3. It can be installed in any position and maintenance is convenient.
4. The seal can be replaced, and the sealing performance is reliable to achieve two-way sealing with zero leakage.
5. The sealing material is resistant to aging, corrosion, and has a long service life.
