Ball valve sealing material

Ball valve sealing performance depends largely on the seal of the material. Ball valve sealing material choice mainly according to the fluid properties, pressure, temperature and other factors, but also should have the following: 1) Has the high corrosion resistance, dissolving resistance. 2) Should have enough strength and properties, such as to debunk many times. 3) Heat-resistant, hardy properties.


ball valve sealing material has two categories, non-metallic materials and metal materials:


1. Non-metallic materials, rubber, engineering plastics and carbon fiber materials sealing material. The use of various materials is closely related to the temperature and pressure, the higher the temperature, the lower the pressure, and vice versa.


2. Metal sealing material. On the ball directly by using the metal sealing material is rare, usually with chromium cobalt tungsten carbide.
