Linear Gap Seal PTFE Spring Energized Radial Seals

Product Name: Teflon spring energized seals are composed of a polymer material sealing shell and a corrosion-resistant stainless steel metal spring. The seal ring is installed in the groove, and the spring is compressed to form an outward tension, which promotes the sealing lip to closely contact the sealing groove.

Product Name: Valve PTFE Spring Energized Radial Seals

When choosing a polymer material for a ball valve seat, there are numerous factors that are involved. Key material properties include …

Sufficient ductility to provide a reliable seal
Dimensional stability to ensure the ball valve seat retains its shape for reliable sealing and performance
Very low friction to keep stem torque at a minimum
Low coefficient of thermal expansion so that the ball valve seat retains its shape when temperature changes occur
Excellent wear resistance for a long service life
Chemical compatibility with all media involved
