Spring Energized Seal

Application Areas

• Aerospace Industry: Withstands high pressure, high temperatures, and harsh weather conditions.
• Biochemical Equipment: Resistant to highly corrosive chemicals.
• Semiconductor Manufacturing: Ensures effective sealing in ultra-clean environments to prevent contamination.
• Food and Pharmaceutical Industries: Compliant with FDA and other hygiene standards.
• Petrochemical Industry: Provides long-lasting sealing in high-temperature, high-pressure piping systems.
• Vacuum Equipment and Mechanical Components: Used for dynamic sealing in sliders, piston rings, and bearings.

Static vs. Dynamic Sealing Functions

• Static Sealing: Suitable for sealing between fixed components (such as flanges and cavities) to prevent fluid or gas leakage.
• Dynamic Sealing: Designed for moving parts such as pistons, rotating shafts, and sliders. Effectively reduces friction, extends service life, and ensures consistent sealing even during high-speed operations and frequent starts/stops.

Key Design Factors for Piston Seals

• Low-Friction Transmission: Minimizes resistance for higher efficiency and positioning accuracy.
• High Pressure Resistance: Suitable for high-pressure or vacuum systems such as hydraulic cylinders and gas control valves.
• Material Reinforcement Options: Carbon or glass fiber-reinforced PTFE is available to enhance strength and wear resistance under various load conditions.

Key Selection Criteria for Sealing Components

• Temperature: Resistant to both high and extremely low temperatures.
• Pressure: Capable of withstanding high-pressure or vacuum system requirements.
• Chemical Resistance: Withstands corrosion from chemical exposure.
• Friction: Designed to reduce wear and extend system lifespan.
