50Helical Spring ball valve stem seal
Helical Spring ball valve stem seal is a high-performance Teflon seal with a special spring inside. The elastic force given by the special spring plus the pressure of the system fluid pushes the sealing lip out, and the sealing lip presses the sealed metal surface to form the required excellent sealing effect.
The use of a spring energized seal can completely improve rubber softening, expansion, wear and other issues, thus greatly improving the service life of the ball valve.
The polymer jacket's material includes PTFE, TFM, PCTFE, etc.
Our design brings the performance of Lip Seal to the next level with remarkable benefits to manufacturers of Cryogenic Trunnion Mounted Ball Valves.
Spring energized seals usually occur in environments that exert excessive pressure on traditional elastic seals: extreme temperature and pressure, high levels of friction and wear, or corrosive media are the most common. Since the high-performance plastic of the spring energized seal is machined, the seal configuration can be changed according to your specific needs.

Advantages: 1. Effectively reduce friction resistance and wear. 2. Greatly improve the sealing performance and service life. 3. Any anti-pollution material can be filled in the groove of the seal. 4. Clean and will not cause pollution. 5. Low friction coefficient, and it is very smooth even in very low speed applications. 6. The starting friction is small, even if the stop time is long or intermittent operation, the low starting power performance can be maintained. |

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 FHB seal design of the spiral spring combined arc lip, and the pressure comes from the inside.
LNG Lip Seal For Filling Guns is commonly used in LNG (liquefied natural gas) filling guns.
ODU Piston seals are work to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
Hammer Union Seals are used in hammer union-style pipe connections to establish flow lines and prevent leakage. It is widely used in the oil & gas industry.
The FDR seal is made of a helical wound spring and a polymer jacket, which is mainly used as a Flange external face seal.
It is an end face spring energized seal with both rigid and flexible elements, which gives consistent contact at the sealing interface.
