High-Performance Sealing Solutions with V-Shaped Metal Spring
The V Spring Energized Seals are high-performance sealing solutions designed by Kaflon for demanding industrial applications.
This series incorporates a V-shaped metal spring (V Spring) as the energizing element, combined with a high-performance polymer jacket such as PTFE, TFM, or filled PTFE, ensuring reliable sealing under extreme operating conditions.
Unlike elastomer-based seals, the V Spring continuously applies a uniform radial load to the sealing lip, maintaining effective sealing even under low pressure, vacuum, temperature fluctuation, or mechanical eccentricity.
Key Advantages
1. Low Friction & Smooth Motion
Uniform spring loading reduces:
Start-up friction
Stick-slip behavior
This makes the HW Series suitable for reciprocating and low-speed rotary motion.
2. Wide Temperature & Chemical Compatibility
When combined with PTFE-based materials, HW Series seals can operate in:
–196°C to +260°C temperature range
Aggressive chemicals and solvents
Dry or poorly lubricated environments
3. Long Service Life & Dimensional Stability
No reliance on rubber elasticity
No hardening or aging
Consistent sealing force over long operating periods

faq
Q1: What is the difference between a V Spring and other spring types?
V Springs provide multiple contact points and a softer elastic response, making them ideal for low-pressure, vacuum, and dynamic sealing. O-Springs and helical springs are typically preferred for high-pressure static sealing.
Q2: Are HW Series V Spring Energized Seals suitable for dynamic applications?
Yes. They are well-suited for reciprocating motion and low-speed rotary applications due to their low friction and controlled wear characteristics.
Q3: Can these seals operate without lubrication?
Yes. PTFE and TFM materials are self-lubricating, making the HW Series ideal for dry-running or poorly lubricated environments.
Q4: Can V Spring Energized Seals replace O-rings or U-cups?
In applications involving high temperatures, aggressive chemicals, vacuum, or wide pressure ranges, V Spring Energized Seals are a superior alternative to conventional elastomer seals.
