【Product Description

PTFE Seated Butterfly Valve is designed to meet the needs of many corrosive environments with strong acid and alkali, petroleum, chemical, food and other special fields. It uses a valve body made of Teflon and has a strong anti-corrosion effect. It can replace stainless steel valve body under normal conditions and has higher cost performance. 

The butterfly valve's disc is mounted in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc-shaped disc rotates around the axis, and the rotation angle is between 0° and 90°.

【Different types of Fluoroplastics

1. PTFE

PTFE Seated Butterfly Valve has high impact strength, but tensile strength, wear resistance and creep resistance are worse than other engineering plastics. Glass fiber, bronze, carbon and graphite are sometimes added to improve their special mechanical properties.

2. PFA

PFA is a soluble polytetrafluoroethylene. PFA is a modified polytetrafluoroethylene with a temperature of 260 ° C. The perfluoroalkoxy resin PFA resin is a relatively new melt processable fluoroplastic. PFA has a melting point of about 580 °F and a density of 2.13 - (g/cm3)

3. NYLON

Its most outstanding advantage is that its wear resistance is superior to other fibers, followed by good elasticity. This material can therefore be used for valve lining materials and valve sealing materials. Use nylon at temperatures below 100 degrees Celsius.
