The difference between pneumatic butterfly valve and gate valve has always been the focus of the industry, because both valves have good market use. The difference between pneumatic butterfly valve and gate valve is mainly reflected in their working mode and use effect. Next, let me introduce the difference between pneumatic butterfly valve and gate valve.

As polytetrafluoroethylene (PTFE) has strong corrosion resistance, stable performance, resistance to aging, low friction coefficient, easy forming, and stable size, it can also be filled and added with appropriate materials to improve its comprehensive performance, and obtain butterfly valve sealing materials with better strength and lower friction coefficient, overcoming some limitations of synthetic rubber, As a result, polymer materials represented by polytetrafluoroethylene and their filling modification materials have been widely used in butterfly valves, which further improves the performance of butterfly valves. Butterfly valves with wider temperature and pressure ranges, longer sealing performance and service life have emerged.
