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
