What are V Spring Energized Face Seals
V Spring Energized Face Seals are designed to provide a reliable seal between two mating surfaces. The V spring is the core part of the seal, which has elasticity and recovery properties. It is designed in a V-shape to generate positive elastic force, allowing the sealing gasket to generate a constant sealing force on the joint surface. The shape of this spring provides additional compression, allowing the seal to adapt to different operating conditions and joint clearances.
Advanced V-Spring Seal Design
Features:
- Provides moderate spring force versus deflection.
- Various spring loads to meet friction and sealing requirements.
- Cross-sections available are 1/16in up to 1/2in.
- Available to fit in all Industrial, Aerospace, and Military gland sizes, with custom sizes ranging from .125" to 48" diameters.
- Peek V-spring is available for non-metallic applications.
Benefits:
- Permits dynamic runout and wide gland tolerances.
- Provides low friction and optimum sealing.
- Excellent in rotary and reciprocating motion.
- Provides excellent scraping/wiping action for sealing abrasive and viscous media with a skived lip design.
- Provides PEEK V-spring for zero-emission of ions.
- Allows for low clamping force.
Product material selection
1. Polytetrafluoroethylene (PTFE): PTFE is a material with good chemical resistance and low friction coefficient. It provides good sealing performance over a wide temperature range and is suitable for many chemical media and high-temperature environments.
2. Polyetheretherketone (PEEK): PEEK has excellent thermal stability, corrosion resistance, and wear resistance. It performs well in high-temperature and pressure environments and is suitable for applications requiring high-performance sealing.
3. Polyurethane (PU): PU has good wear resistance and oil resistance, and is suitable for applications requiring wear resistance and oil resistance. It also has high elastic recovery and can adapt to different sealing surface gaps.
4. Metal materials: Some applications may require the use of V spring seals made of metal materials, such as stainless steel, titanium alloy, etc. Metal materials have high strength and corrosion resistance and are suitable for high temperature, high pressure, and occasions requiring high sealing force.
5. Fluorine rubber (FKM): FKM has good chemical resistance, thermal stability, and wear resistance. It is suitable for applications requiring corrosion resistance and high-temperature sealing and is especially widely used in the petrochemical, automotive, and aerospace fields.
These are just some common V Spring Energized Face Seals material options. The specific selection should be determined based on the specific requirements of the application, such as working environment, media characteristics, and temperature range.
Applicable working conditions
V spring energy seals are suitable for many different operating conditions, especially those requiring high sealing performance. The following are some common applicable working conditions:
1. High-temperature environment: V Spring Face Seals can provide reliable sealing performance under high-temperature conditions. They are typically able to withstand operating temperatures up to 300°C or higher and are suitable for applications such as thermal processing equipment, combustion plants, and high-temperature chemical processes.
2. High-pressure environment: Because V Spring Face Seal has built-in springs, they can provide higher sealing pressure and are suitable for high-pressure working conditions. This makes them ideal for applications such as gas compressors, hydraulic systems, high-pressure valves, and pipe connections.
3. Chemically corrosive environment: V Spring Energized Face Seals can be made of a variety of chemically resistant materials, such as polytetrafluoroethylene (PTFE) and fluoro rubber (FKM). This makes them ideal for applications dealing with corrosive media, such as chemical plants, the oil and gas industry, etc.

4. High vacuum environment: V spring seals can provide reliable sealing performance under high vacuum conditions, such as vacuum equipment, semiconductor manufacturing, and spacecraft applications.
5. High-speed rotating equipment: Because V spring seals have good sealing performance and anti-vibration capabilities, they are suitable for high-speed rotating equipment, such as centrifugal pumps, compressors, and turbines.
It is worth noting that each application has its specific working conditions and requirements, so when selecting V Spring Energized Face Seal, the most appropriate material and design should be determined based on the specific working conditions and application requirements.
