CP valve: The best way to tackle extreme differences in temperature and dry gases
The liquefaction and vaporisation of gases exact high demands in terms of efficiency and service life A wide temperature range and extreme dryness of gases place extra demands on the compressor valves.

■ No secondary damage caused by broken fragments of metal valve plates
The revolutionary, profiled valve plate
The CP valve from HOERBIGER delivers clearly improved efficiency and a longer service life Greater resistance across a wide temperature range due to the use of well proven HP material.
Profiled HP valve plates reduce valve losses and can be used over a wide temperature range from –200° C to 220° C
CP valves in actual operation have delivered ■ Reductions of up to 40% in valve losses ■ Savings of up to 4% in electrical energy ■ Considerably longer service life
Special springs designed for maximum dynamic reliability
Integrated anti-rotating device guarantees reliable unloader operation
