Spring Seals Used in Valve Strict Environment

Xlong seal spring energized seal is a U-shape spring energized seal function with single acting sealing element. The spring which energized the PTFE jacket actuates the sealing legs(lips) of the seal. The system pressure assists the spring in creating a leak tight seal between the sealing lips and the mating metal parts. The springs assist in slight misalignment, jacket wear, and maintaining a consistent sealing pressure against the desired target.

Spring energized seal has been designed specially to overcome the problems associated with PTFE composite or other high performance plastics like UHMW-PE and elastomer. They are suitable for static, rotary, and reciprocating application in temperatures from -200 º C to 300 º C, pressure from vacuum to 700kg/cm and speed up to 20m/s, to survive the most corrosive enviroment. Three different types of spring energizer are made from corrosion resistant metal alloys such as stainless steel, Elgiloy and Hastelloy to meet most serious corrosive and high temperature application.

Standard spring energized seal are precisely machined to fit AS 568A glands in radial rod, piston and axial face-seal configurations. Spring energized seal can replace most of o ring used in mechanical seal and extend total sealing performance and service life in very aggressive chemical, petrochemical process.

Spring engerized seal are used in dynamic and static applications where elastomer seals cannot meet the extreme operating conditions of harsh environment. Furthermore, spring enegized in hydraulic components where low friction, high lateral load, corrosive of steam environment are required.
