STANDARD

The fully lined fluorine (PTFE) seat butterfly valve is a valve that uses a disc-type opening and closing member to reciprocate around 90 degrees to open, close, and adjust the fluid channel. With the application of chemically resistant synthetic rubber to butterfly valves, fully lined fluorine butterfly valves have also been widely promoted. Because polytetrafluoroethylene (PTFE) has strong corrosion resistance, stable performance, not easy to age, low friction coefficient, easy to form, It is dimensionally stable, and it can also be filled and added with appropriate materials to improve its overall performance, resulting in a metal hard-sealed butterfly valve with better strength and lower friction coefficient.

Therefore, polymer polymer materials represented by polytetrafluoroethylene and its filling modified materials have been widely used in butterfly valves, so that the performance of butterfly valves has been further improved, a wider temperature and pressure range, and sealing performance , Butterfly valve with longer service life.

Due to the application of computer-aided design (CAD), computer-aided manufacturing (CAM) and flexible manufacturing system (FMS) in the valve industry, the design and manufacture of fully lined fluorine butterfly valves has reached a whole new level. Not only has the valve design calculation method been completely renovated, but also the heavy and repetitive routine design work of professional technicians has been relieved, so that the technicians have more energy to improve the technical performance of products and the research and development of new products, shortening the cycle and improving Labor productivity.
