Design Features:
Polytetrafluoroethylene (PTFE) has strong corrosion resistance, stable performance, not easy to age, low friction coefficient, easy to form, and stable in size. Polymeric materials represented by polytetrafluoroethylene and their filling and modified materials have been widely used in butterfly valves, so that the performance of butterfly valves has been further improved. The fully lined fluorine butterfly valve adopting this technology has a wider temperature and pressure range, a longer sealing performance and a longer service life.
1. The design is novel and reasonable, the structure is unique, the weight is light, and the opening and closing is rapid.
2. Small operating torque, convenient operation, labor-saving and smart.
3. It can be installed in any position and is convenient for maintenance.
4. The seals can be replaced, and the sealing performance is reliable to achieve zero leakage in two-way sealing.
5. The sealing material has a wider temperature and pressure range, is extremely corrosion-resistant, has better sealing performance and longer service life.
