710 (single acting, slow/static)
Utilizing a strong helically wound spring in combination with a PTFE seal jacket will ensure a good seal ability in static or slow moving applications.
The helically wound spring has the benefit of having a high spring force at a low compression rate, compared to a seal energized by a V-spring. This makes it more suitable for applications with extreme temperature fluctuations, such as cryogenics.
Advantages:
- Tight seal in static or slow moving applications
- Very high chemical resistance, compared to similar seals using rubber O-rings
- Long shelf life
- Resistant to wear and tear
Limitations:
- Operation pressure: Up to 80 MPa (800 bar)
- Velocity: 4 m/s
- Temperature: -130°C to 260°C
