Electric regulating valve Type CCMT 2, 8, 16 and 42
One valve, 4 applications: HPV, GBV, EV and EPR
The CCMT is an electrically operated valve designed specically for operation in CO
systems.
The CCMT valve concept is designed to full global refrigeration requirements.
The valve is capable of functioning either as an expansion valve, as a pressure regulator for the gascooler or as a gas bypass valve with back­pressure regulation in transcritical or subcritical applications.

Applications
The CCMT valve is developed for transcritical CO2 applications. The CCMT valve can be used in systems with ash gas bypass, parallel compression as well as in stand-alone applications.
The CCMT valve can be used in transcritical and subcritical conditions.
CCMT valves are typically used as ash gas bypass and high pressure regulation.
Figure 1: Application
Application 1 - High Pressure Valve (HPV)
The function of the high pressure valve is to control the high pressure in the system according to the reference from the controller. The reference can be set to obtain the optimum COP, optimum capacity or any other factors. Pressure optimization is performed by the CCMT valve, which is installed at the outlet of the gas cooler (see the gure above) and a matching Danfoss controller. This design provides the possibility to optimize gas cooler pressure in all situations and intermediate receiver pressure independently. Please refer to the www.danfoss.com/CO2 for more information on CO2 systems.
Application 2 - Gas bypass Valve (GBV)
A gas bypass valve is typically used to regulate the intermediate pressure in a transcritical CO2 refrigeration system, in order to keep the intermediate pressure low. By venting ash gas generated through a gas bypass valve to the suction side of the compressor after the transcritcal expansion, the pressure can be kept at a safe level for all components situated in the liquid lines of a transcritical CO2 system . The two phase mixture from the CCMT valve has to be separated before gas enters the gas bypass. For use in the gas bypass applicaton the EKC 326A controller is recommended for CCMT 2 to CCMT 8
Application 3- Expansion Valve (EV)
A liquid expansion valve is typically used for injection in plate heat exchangers of CO2/CO2 cascades, or as an expansion valve for CO2 evaporators. For the liquid injection applications CCMT 2 to CCMT 8 is used with EKC 313 controller.
Application 4 – Electric pressure regulator (EPR)
With CCMT valves, it is possible to obtain an accurate temperature or pressure control by modulating the pressure in the evaporator.

Figure 2: CCMT valve
If the controller driving the CCMT Light valve is from another manufacturer than Danfoss or a custom design, the following points must be considered in order to overcome potential step loss.
To ensure total closing of the valve, and to compensate the lost steps after a dened number of changes in opening degree. the controller should have a function to overdrive the valve in the closing direction. It is recommended to overdrive ten percent of the full steps range at appropriate intervals.
WARNING:
At power failure the CCMT Light valve will remain in the actual opening position it has at the moment of power failure, unless a safety device in the form of a battery backup is installed.

M12 angle cable
M12 angle cable
M12 angle female connector is intended for use with the standard M12 male connector on CCMT Light valves. The Danfoss cable is designed to oer high exibility and proper tensile strength. The Danfoss M12 cable also consists of paired, twisted wires, which decreases mutual inuence between signals transmitted along the cable and reduces inuence of external sources of interference. The cable thus provides a higher degree of protection against lost steps compared to other cables.
