Product Description

The PTFE Spring Energized Valve Seal is a spring- energized, pressure-assisted sealing device consisting of a PTFE (or other polymer) seal partially encapsulating a corrosion-resistant metal spring energizer.


The PTFE jackets are precisely machined, filled with PTFE composites and other high performance polymers, function at temperatures ranging from cryogenic to 250 C and inert to almost all chemicals. Some types also can be used in sanitary environment.


Because of their particular qualities, PTFE spring seals are extensively employed in valves and seats. PTFE, or polytetrafluoroethylene, is a synthetic substance with a low coefficient of friction and a great resistance to chemical corrosion. Because of these characteristics, PTFE is an excellent material for use in valve and seat seals, where it may help prevent leaks and ensure a tight seal.


The spring in PTFE spring seals adds compression and support to the seal, allowing it to conform to uneven surfaces and compensate for wear over time. Even in high-pressure and high-temperature situations, this helps to maintain a constant seal and avoid leakage.


Overall, PTFE spring seals provide a dependable and cost-effective alternative for sealing valves and seats in a variety of industrial applications such as chemical processing, oil and gas, and pharmaceuticals.
