Helical spring stem seals are advanced spring energized Teflon seals specially designed for ball valve applications. The sealing mechanism relies on the elastic force of the helical spring combined with system pressure, which pushes the sealing lip firmly against the valve stem or metal surface. This ensures reliable, long-lasting sealing performance even under the most demanding conditions.
Compared to conventional elastomer seals, spring energized seals overcome issues of rubber softening, swelling, and wear, significantly extending the service life of cryogenic and high-pressure ball valves.

Spring energized seals for ball valves are advanced sealing solutions designed for rod and dynamic sealing applications in demanding industries such as oil & gas, LNG, and cryogenics. By combining a helical wound spring with a polymer jacket, these seals deliver consistent sealing force, high wear resistance, and reliable performance under extreme conditions where standard polymer seals fail.

High-pressure lip seals are precision-engineered sealing solutions designed for ball valve stem sealing under demanding conditions. By combining a canted coil spring with a high-performance polymer jacket, these seals provide consistent sealing force, excellent wear resistance, and reliable performance in cryogenic, high-pressure, and chemically aggressive environments.

API 6D piston seals are designed to provide long-term, reliable sealing performance in demanding ball valve applications. By combining a helical wound spring with a high-performance polymer jacket, these seals deliver consistent sealing force, chemical resistance, and stability under extreme temperature and pressure conditions.

The ball valve seat plays a critical role in sealing the process fluid and distributing the seating stress evenly across the contact surface. In petrochemical and energy applications, even a minor leak can be environmentally devastating and cause costly downtime. To address these challenges, high-pressure seat seals are designed with superior sealing integrity, durability, and adaptability to extreme service conditions.

In LNG operations, cryogenic ball valves must withstand extreme service conditions, including temperatures as low as –320°F (–196°C) and pressures above 750 psi. These valves are also exposed to repeated thermal cycling, which causes expansion, shrinkage, and additional material stresses. Such harsh environments make achieving reliable, long-term valve sealing an engineering challenge.

Cryogenic ball valves are widely used in LNG systems, where extreme low temperatures, high pressures, and aggressive media place unique demands on sealing performance. A critical component of these valves is the cryogenic ball valve seat seal, which ensures reliable tightness and safety during operation.

Cryogenic PTFE Spring Energized Seals are specifically engineered to provide reliable sealing performance in harsh cryogenic systems where ultra-low temperatures, high vacuum, and high pressures are present. 
Constructed with a helical wound spring and a PTFE-based polymer jacket, these seals are primarily used as flange internal face seals in cryogenic devices. Compared with traditional O-rings, spring energized seals deliver superior friction control, dimensional stability, and extended wear life, ensuring a long-lasting and leak-free seal even under deep cryogenic conditions.
They are widely applied in valve flange connections, cryogenic piping systems, and LNG equipment where leakage prevention is essential.

Metal-Faced PTFE Spring Seals are advanced static sealing solutions that combine the strength of a helical wound spring with the chemical resistance of PTFE-based polymers. This unique design ensures reliable performance in extreme cryogenic, chemical, and low-pressure applications.
The helical spring energized static face seal uses a spiral spring with an arc-shaped lip profile. The sealing force is generated both by the internal system pressure and the continuous radial load of the spring. This dual mechanism ensures excellent sealing efficiency, even at ultra-low temperatures and fluctuating pressures.

Helical Spring Energized Seals are advanced sealing solutions designed to withstand the harsh conditions of oil and gas operations, including cryogenic temperatures, high pressures, and corrosive media.
The low-temperature PTFE spring energized seal is typically used as a single piston seal for valves. When the working pressure is ≥1500LB, a high-strength backup ring can be added to protect the sealing lip from extrusion or damage.
Constructed from PTFE + Helical Elgiloy® Spring, these seals can be customized with different polymer and spring materials to suit various temperature and pressure requirements. They are widely used in API 6D ball valves for ultra-low temperature (–196℃) and normal temperature sealing applications.

Spring Energized Seals for LNG Nozzles are high-performance cryogenic sealing solutions designed for LNG fueling systems.
In practice, they are also widely known as LNG Lip Seals for Filling Guns, since they are commonly used in LNG filling guns and nozzles to ensure safe, reliable, and leak-free fueling operations at ultra-low temperatures.
The seal consists of a high-grade polymer jacket combined with a heat-treated Elgiloy® alloy spring. The spring provides continuous radial force, ensuring effective sealing even under low temperatures, low pressures, or sub-optimal surface finishes. Compared with traditional rubber seals, spring energized seals prevent softening, expansion, and wear, significantly extending service life.

The high-pressure bidirectional seat seal is a precision-engineered sealing element designed for API 6D ball valves. It ensures tight sealing performance in both upstream and downstream directions, making it ideal for pipeline isolation, LNG service, and high-pressure oil & gas applications.
