CCMT Electric Regulating Valve

Brand: Danfoss

The CCMT is an electrically operated valve designed specifically for operation in CO₂ systems. 

The CCMT valve concept is designed to fulfil global refrigeration requirements. 

The valve is capable of functioning either as an expansion valve, as a pressure regulator for the gas cooler or as a gas bypass valve with backpressure regulation in transcritical or subcritical applications.
Features
  • Designed for CO2 systems with maximum working pressure of 140 bar / 2,030 psig
  • Applicable to R744 (CO2) and other common refrigerants. The CCMT is compatible with the oil types PAG, POE and PVE
  • Regulating cone ensures optimum regulating accuracy, particularly at part load
  • Patented cone and balance design
  • The PEEK seat provides excellent valve tightness and robustness
  • Combined butt weld and solder connections
  • Top part with built-in strainer / filter
  • MOPD up to 90 bar / 1,305 psi
  • CCMT 16 – CCMT 42 is available with or without integrated pressure transmitter
  • Standard M12 connector for simple and flexible connection to the motor driver
  • Low weight and compact design
  • Easy to service. Insert easily taken out by removing top part
  • For manual operation and service of the CCMT an AST-g service driver is available
