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
