Introduce
Ball valve seat gaskets are often utilized within the ball valve's valve body, near to the ball. It is normally situated above the ball valve's valve seat and is fastened in the valve body's seat groove. When you close the ball valve, a tight sealing contact forms between the ball and the seat ring, preventing the medium from flowing through the valve. When the ball valve is opened, the ball spins and the seat ring separates slightly from the ball, enabling the medium to flow through the valve.To guarantee high sealing performance, the seat ring material is typically elastic, such as polytetrafluoroethylene (PTFE), etc. To satisfy the needs of certain applications, the seat ring should be suitably selected based on criteria such as medium properties, operating pressure, and temperature.
Advantage
The ball valve seat seal is a key component in valve systems, providing excellent sealing performance and preventing media leakage. Manufactured from a high quality elastic material, it provides a reliable seal even in high pressure and high temperature environments. The gasket is also corrosion resistant, extending the life of the valve. It can withstand rotational friction and the impact of liquid media while maintaining good sealing performance. The gasket's low coefficient of friction makes valve operation more flexible and smoother, reducing torque and operating resistance. This improves the control accuracy of the valve.
