Learn more about latest pioneering 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:

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

Increased design freedom with our premium compressor valve products

Our premium compressor valve steels enable higher valve lift, leading to increased compressor efficiency. Reduced length of valve with maintained lift enables miniaturization of the valve.

They are well suited for use in compressors where higher pressures, frequencies and temperatures place increasing demands on the valve.
