In the valve industry, the PTFE Valve Seat is an important component. Using PTFE, a synthetic fluoropolymer, provides a higher class of valve. PTFE has excellent properties like chemical inertness, low coefficient of friction, and excellent thermal resistance. Hence, the PTFE Ball Valve Seat is ideal for creating a tight seal between the valve body and the closure element (such as a ball, disc, or plug). The main function of using the PTFE Valve Seats for Ball Valves is to provide tight, leakproof, reliable, and efficient flow control. They are ideal for various industries.
