Increased design freedom with our Hiflex™ compressor valve steel

Our 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.

Our 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 our Hiflex™ compressor valve steel
