ProductsHigh Pressure CO2 Expansion Valve CX Series
The launch Of High Pressure Expansion Valve Series For CO2 Gascooler Applications By Emerson Climate Technologies The newly launched stepper motor driven valves ensure precise control of R744 refrigerant mass flow in air conditioning, refrigeration and heat pump applications. The series called CX features a maximum working pressure of 120 bar and can be used as high pressure expansion valve, but also for general control applications such as liquid injection or hot gas bypass control.
The valve series is perfectly suitable for transcritical CO2 applications. In addition, the fully hermetic design ensures high quality and security as the design avoids threaded joints between valve body and motor compartment.
The series includes the models CX4, CX5, CX6 and CX7 with flow rates (kv value) varying from 0.21 to 5.58 m3/h.
