LNG nozzle spring energized seals manufacturer

The ball valve seat is responsible for sealing the fluid inside and uniformly distributing the seating stress. A leak of ball valve in petrochemical application could be environmentally devastating.

The BVR series is made of a canted level spring and a polymer jacket, which is mainly used as a stem seal.

The spring energized seal is a high-performance Teflon seal with a special spring inside.

The FHB seal design of the spiral spring combined arc lip, and the pressure comes from the inside.

Nylon BX R RX style Test Ring Gasket is good for valve pressure test. JST Nylon ring joint test gaskets are a no damaging method to test and re-certify ring type joint flanges.

JST's back up ring compensate for large temperature fluctuations. Using Back-up Rings allows O-Rings to be utilized in higher pressure applications, where larger extrusion gaps are required and where there are reciprocating or rotating movements. Back-up Rings are protective and supporting elements with no sealing function. The back up ring material could be  PEEK, modified PTFE.

Rod seals are static seals installed in glands or housings to prevent the leakage of fluid from within a cylinder to the outside as the rod cycles.

This is sealing product developed by JST to meet the increasingly demanding sealing needs of equipment manufacturers and users in semiconductor, petrochemical, mechanical seal, instrumentation, energy, biopharmaceutical, food and medical industries.
