WS-SEALS PTFE Stainless Steel Spring Energized Seals Valve Seal Variseal Spring Loaded Seals

Working Principle

Its working principle is based on the pre - tightening force provided by the spring. When installing Spring Energized Seals, the elastic force generated by the spring makes the sealing material adhere tightly to the sealing surface, thus forming an initial seal. During the operation of the equipment, regardless of how the system pressure changes, the spring can automatically adjust the contact force between the sealing material and the sealing surface according to the pressure fluctuations. When the pressure increases, the spring is further compressed to enhance the sealing effect; when the pressure decreases, the spring recovers part of its deformation to maintain a reliable sealing contact, effectively preventing the leakage of fluids (liquids or gases) at all times.

Product Advantages 

- Excellent Sealing Performance: It can maintain excellent sealing effects under extreme working conditions such as high pressure, high temperature, high vacuum, and chemical corrosion, ensuring the reliability and stability of equipment operation.

- Wide Applicability: It can adapt to a variety of different fluid media, including various oils, chemicals, water, etc. At the same time, it is suitable for multiple sealing application scenarios such as rotary, reciprocating, and static seals.

- Long Service Life: Due to the wear resistance of the elastic sealing material and the lasting elastic force of the spring, compared with traditional seals, Spring Energized Seals have a longer service life, reducing the maintenance cost and downtime of equipment.

- Good Adaptability: It has relatively low requirements for the smoothness and machining accuracy of the sealing surface, can adapt to a certain degree of surface unevenness, and reduces the difficulty and cost of seal installation and equipment manufacturing.

 Application Fields 

- Aerospace: Used for the sealing of key parts such as aircraft engines, hydraulic systems, and fuel pipelines to ensure flight safety and equipment performance.

- Automotive Manufacturing: Applied to components such as engines, transmissions, and braking systems, ensuring the stability of vehicle power transmission and operation and reducing the risk of leakage.

- Petroleum and Chemical Industry: In refining and chemical production equipment, such as reaction kettles, pipelines, pumps, etc., it can resist high temperature, high pressure, and highly corrosive media and prevent leakage from causing safety accidents.

- Food, Beverage, and Pharmaceutical Industries: Meeting hygienic requirements, it is used for the sealing of food processing equipment and pharmaceutical machinery to avoid product contamination and comply with strict industry standards.
