The spring energized gaskets (Spring Seal) are composed with high performance Polymer materials and corrosion resistant metal ring or spring. This type of gasket is designed to operate at cryogenic temperatures at -200 ° C to high temperatures up to 300 ° C or more.,4 pron com
pure mature,The inner spring is installed in the groove, the tension (elasticity) formed by the compression spring to make the sealing lip close to the groove can make up for the wear of the sealing shell and the eccentricity of matching parts, forming the sealing from vacuum to low pressure. The greater the pressure, the tighter the sealing lip and groove fit.
mporn pics,The metal springs may take the spiral or comb form( O-shaped, V-shaped and U-shaped) to meet the sealing requirements of different movements. In some cases, it can be used as elastomer O-ring instead of metal spring.
The outer ring is machined from high-performance polymeric materials like PTFE, PEEK, PTFE, Dyneon and other most resistant polymers, suitable for temperatures ranging from -196 ° C to +296 ° C, isolating almost all liquids, chemicals and gases and allowing unlimited storage without aging.,fucked well
Sealing performance is guaranteed not affected by insufficient lubrication;
Produced by CNC processing methods, need no mold cost, ideal for small number of diverse seal parts;
The combination of different sealing materials and springs can effectively reduce the abrasion and friction resistance and realize different sealing performance to meet various valve application requirements such as operating pressure, temperature, fluids or gases of the flow.
Better chemical corrosion resistance and heat resistance than the common rubber seals, no sealing performance failure caused by expansion or shrinkage.
