HF Flange Seals DVE401920-T05S for Internal Pressure

Description
Variseal HF is the standard seal for axial (face) applications. It has a high

spring loading, which gives excellent sealing integrity at low pressure and is available

for both internal and external pressure.

The heavy helical spring in Variseal HF makes it the best choice for vacuum, gas and low

temperature flange sealing applications.

Areas of Application
- Compressor housings
- Construction equipment and plant
- Chemical processing
- Crude oil and natural gas installations
- Cryogenic engineering
- Nuclear power
- Vacuum applications
- Pivot joints







The operating temperature can range from refrigerant to 300°C, the pressure is from vacuum to ultra-high pressure 700kg/cm2 (about 70MPa), and the moving speed is up to 20m/s. The spring can be selected from stainless steel, corrosion-resistant alloy, etc. according to different use environments, so it can be applied to various high-temperature corrosive fluids.
