variseal spring energized seal for dispensing valve
Spring Seal | Spring Energized Seal | High-Performance Seal with
Built-In Special Spring
Discover our advanced spring seals, also known as spring energized
seals, featuring a built-in special spring that delivers high
performance. These seals utilize the perfect combination of spring
force and system fluid pressure to gently press the sealing lip
(face) against the metal surface, ensuring an excellent sealing
effect. The spring’s actuating effect compensates for slight
eccentricities in the metal mating surface and the wear of the
sealing lip, maintaining optimal sealing performance. Choose our
spring seals for superior durability and reliability in your
applications.
| Characteristics | Details |
|---|
| 1. Lubrication Independence | Sealing performance is not affected by insufficient lubrication at
start-up. |
| 2. Wear and Friction Reduction | Effectively reduces wear and frictional resistance. |
| 3. Customizable Sealing Forces | Combines different sealing materials and springs to display various
sealing forces to meet diverse application requirements.
Manufactured using special CNC processing machines, eliminating
mold costs—ideal for producing small quantities of various seals. |
| 4. Superior Chemical and Heat Resistance | Offers superior chemical and heat resistance compared to commonly
used seal rubber. Dimensionally stable, with no deterioration in
sealing performance due to volume swelling or shrinkage. |
The combination of engineering plastics and corrosion-resistant
metal springs can meet the increasingly stringent industrial needs
of the industry. Typical applications are as follows:
1. Axial seal for loading and unloading arm rotary joint
2, spray valve parts or other paint system seals
3, vacuum pump seals
4. Beverage, water, beer filling equipment (such as filling valves)
and seals for food industry
5, automotive, aerospace industrial seals, such as power steering
6. Sealing device for measuring equipment (low friction, long life)
7. Seals for other process equipment or pressure vessels
Sealing principle
The PTFE leaf spring combination U-ring seal (pan-plug seal) is
pressed by the appropriate spring tension plus system fluid
pressure to gently press the sealing lip to form a very good
sealing effect. Working limit: Pressure: 700kg/cm2 Temperature:
-200--300°C Line speed: 20m/s Use medium: oil, water, steam, air,
solvent, medicine, food, acid and alkali, chemical solution.
