Electric regulating valve
Type CCM

Expansion and gas bypass valve for CO

2

The CCM is an electrically operated valve
designed specically for operation in CO

systems. The valve is capable of functioning
both as an expansion valve, and as a gas bypass
valve with back-pressure regulation in
subcritical applications.

The pressure rating allows for operation in
environments where system standby capability
is required without the need for auxiliary
cooling systems during servicing or power
outages.

Features:

• Up to 90 bar (1305 psi) working pressure to
accomodate CO2 system pressures during

standstill conditions.

• Precise positioning for optimal control of
intermediate pressures in transcritical CO

systems or liquid injection in heat
exchangers.

• MOPD up to 50 bar (725 psi).

• Combined stainless steel butt weld/solder
connections for installation in copper piped
systems (K65 alloy or standard) as well as
steel piped systems.

• Standard M12 connector for simple and
exible connection to the motor driver.

• For manual operation and service of the CCM
an AST-g service driver is available. For further
information please contact Danfoss
(Commercial Refrigeration and Air
Conditioning Controls).

• UL recognized.

Applications

The CCM can be used in a variety of applications within CO2 refrigeration systems. Typically it is used as a gas bypass
valve in a transcritical CO2 booster system or as an expansion valve.

Figure 1: Application 1

A gas bypass valve is typically used to regulate the intermediate pressure in a transcritical CO2 refrigeration system.
By venting ashgas generated after the transcritical expansion, the pressure can be kept at a safe level for all
components situated in the liquid lines of a transcritical CO2 system. For use in the gas bypass application the
EKC326A controller is recommended.

Figure 2: Application 2

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 CCM is used with EKC 316A controller.

M12 angle cable

M12 angle female connector is intended for use with a standard M12 male connector, available on stepper motor
valves.

This cable is designed to oer high exibility and small outer diameters with tensile strength. The angle way M12
cable consist 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 cables thus provides a higher degree of
protection against lost steps compared to other cables.
