Cryogenic PTFE Spring Energized Seal For Valve

Cryogenic PTFE Spring Energized Seal For Valve is a single-piston seal. The working temperature range is -200~260 and the pressure is 2500LB. When the pressure is greater than or equal to 1500LB, a high-strength back-up ring can be added at the root. A Support ring will be added in front of the sealing lip when there’s pressure coming from back to protect the sealing lip from being damaged. It is composed of PTFE + H-type spring. Different material can be used for different temperature and pressure. Normally It is used in 6D ultra-low temperature (-196°) and normal temperature both.
