50Helical alloy spring energized seals for medical device
The spring energized seal is widely used in medical equipment, which is generally composed of a corrosion resistant spring and a seal ring made of U-shaped filled PTFE/UPE material. Working in the temperature range from -196℃ to 121 ℃, suitable for complicated chemicals.
Spring seals are popular in the medical device industry for many reasons, because of their low friction, chemical resistance, and excellent performance under various pressures, temperatures and speeds. Spring actuated PTFE seals provide a reliable sealing solution that is effective even in low pressure environments. Even if JST's existing energized PTFE seals cannot meet your needs, you can customize and design appropriate energized PTFE seals according to requirements and specifications.
JST provide customers with various types of spring energized seal products, which have been widely used in occasions with high requirements for durability, chemical resistance and work at extreme temperatures. They are widely recognized in the LNG industry, oil production, petrochemical, compressor, semiconductor, hydraulic equipment, and medical equipment industries.

Spring energized PTFE seals consist of variety of jacket profiles and spring types. It can achieve the sealing effect compensation under different pressure conditions by spring energizer.
The seal jacket of adhesive dispenser/dispensing seal is made of ultra-high molecular UHMWPE or PEEK, with installed stainless steel anti-corrosion spring with low temperature resistance treatment.
The valve stem packing is an essential component of valves, which is covered around the valve stem. The purpose of valve packing is to prevent leakage.
Wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system.

The bonded seal is used in work-over and sand control operations. With the bonding of elastomer to a steel core, this serve to prevent excessive rubber compression under loading.
In LNG operations, valves can regularly encounter temperatures below -320 F (-196 C) and pressures above 750 pounds per square inch (psi). They are also subjected to periodic variations in temperatures known as “thermal cycling,” which can result in hardware expansion as well as shrinkage and material stresses. These factors make reliable, long-term valve operation an engineering challenge.
The PTFE gate valve seat seal is made of durable teflon, it is compatible with the Cameron gate valve type FC, FLS, and used in rotating equipment to minimize o-ring movement.
