Metal face spring PTFE seals supplier

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.

LNG Lip Seal For Filling Guns is commonly used in LNG (liquefied natural gas) filling guns.

Back-up Ring/Anti Extrusion Rings is a ring that holds an elastomeric seal to its outline shape and in its right place. and are typically used with O Rings to eliminate extrusion at high pressures.

EVZ is commonly used in high-pressure mud pumps and fracturing pumps, namely Packings, the high-speed reciprocating dynamic seals.

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.
