Compressor valve steel

Hardened and tempered strip steel for manufacturing many types of valves:

Compressor valves, reed valves, check valves, flapper valves, relief and relieve valves, explosion valves, diaphragms, lamellas, emergency valves, shutting and shut-off valves. They are used in, among others, the following applications:

  • Air conditioning equipment
  • Brake systems
  • Heat pumps
  • Industrial air compressors
  • Refrigerators and freezers
  • Vacuum pumps

Increased design freedom with Sandvik Hiflex compressor valve steel

Sandvik Hiflex compressor valve steel enables higher valve lift, leading to increased compressor efficiency. Reduced length of valve with maintained lift enables miniaturization of the valve.

Sandvik Hiflex compressor valve steel is well suited for use in compressors where higher pressures, frequencies and temperatures place increasing demands on the valve. Read more about Sandvik Hiflex compressor valve steel
