Product overview:
PTFE butterfly valve is to meet the needs of some corrosive environments with strong acid and strong alkali, petroleum, chemical, food and other special fields. The valve body made of PTFE has a strong anti-corrosion effect. . It can replace the stainless steel valve body under normal conditions 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 channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0¡ã and 90¡ã. When it rotates to 90¡ã, 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 disc rotates around the axis, and the initial position of the valve is determined according to the actual demand. When the valve rotates 90¡ã from the initial position, an action ends (from open to close, or from off to on), otherwise another action (from off to on, or from on to off) ends.

Product Features:

1. Pneumatic wafer butterfly valve is simple in structure, small in size and light in weight. It is composed of only a few parts and is easy to install.

2. When the pneumatic wafer butterfly valve is in the fully open position, the thickness of the disc is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics.

3. Pneumatic wafer butterfly valve has two types of seals: elastic seal and metal seal. Elastic sealing valve, the sealing ring can be inlaid on the valve body or attached to the periphery of the disc.

4. Pneumatic wafer butterfly valve has a long service life, but it is difficult to achieve complete sealing. Metal seals can adapt to higher operating temperatures, while elastomeric seals have the disadvantage of being limited by temperature.

5. The ingenious wedge-shaped design enables the pneumatic wafer ball valve to have the automatic sealing function of closing and tightening.
