Reed valves, leaf valves, and valve retainers are mechanical components commonly used in refrigeration compressors in the civil, industrial, and automotive sectors for the regulation of the refrigerant gas flow during intake and unload.
The main characteristic of these valves is their capability to withstand the stress created by repeated bending without breaking.
This is a hardened and tempered carbon steel characterized by:
- High fatigue strength under bending and impact stress
- A low level of non-metallic inclusions
- Good wear resistance
VOESTALPINE UHB 20C
UHB 20C is a 1% carbon steel with high tensile strength. It is hardened and tempered to a fine martensitic structure to provide the highest fatigue strength among all carbon steels.
ALLEIMA® 7C27Mo2 is a hardened and tempered martensitic stainless steel alloyed with molybdenum. It shares some of the characteristics of ALLEIMA® 20C, but features excellent fatigue strength under bending and impact stress, and a high compressive residual surface stress.
VOESTALPINE UHB SS716
UHB SS716 is a martensitic stainless steel specifically designed for compressor valves. It is characterized by toughness and impact fatigue strength even at temperatures up to 400°C.
