ICM
Motor valve
Application
ICM valves are intended for regulation of expansive processes in
liquid lines with or without phaseshift, or for control of the pres-
sure or the temperature in dry
Function
ICM motor valves belong to the ICV (Industrial Control Valve) fam-
ily. The motor valve comprises three main components: valve
body, combined top cover/function module and actuator.
ICM are direct operated motorised valves driven by actuator type
ICAD (Industrial Control Actuator with Display).
ICM valves are designed so that the opening and closing forces
are balanced, therefore, only two sizes of ICAD actuators are
needed for the complete range of ICM from DN 20 to DN 65. The
ICM motorised valve and ICAD actuator assembly oers a very
compact unit with small dimensions.
The ICM motorised valve and ICAD actuator combinations are as
follows:
Actuator ICAD 600 ICAD 900
Valve size
ICM 20 ICM 40
ICM 25 ICM 50
ICM 32 ICM 65
ICAD 600/ICAD 900
ICAD actuators can be controlled using the following signals:
• 0-20 mA
• 4-20 mA (default)
• 0-10 V
• 2-10 V
ICAD actuators can also operate an ICM valve as an On/O func-
tion supported by a digital input.
The ICM valve can be operated manually via the ICAD actuator or
the Multi-function tool for ICM (see the ordering section).
Fail Safe supply options
In the event of a power failure, multiple fail safe
options are possible, provided that a ICAD-UPS or similar is used.
During power failure, ICM can be selected to:
- Close ICM
- Open ICM
- Stay in the same position, as when power failure occurs
- Go to a specic ICM valve opening degree
Advantages
• Designed for Industrial Refrigeration applications for a maximum
working pressure of 52 bar/754 psig.
• Applicable to all common refrigerants including R717 and R744
(CO
2
) and non corrosive gases/liquids.
• Direct coupled connections.
• Connection types include butt weld, socket weld, solder and
threaded connections.
• Low temperature steel body.
• Low weight and compact design.
• V-port regulating cone ensures optimum regulating accuracy
particularly at part load.
• Cavitation resistant valve seat.
• Modular Concept
– Each valve body is available with several
dierent connection types and sizes.
– Valve overhaul is performed by replacing
the function module.
– Possible to convert ICM motor valve to ICS servo valve.
• Manual opening possible via ICAD or Multi-function tool.
• PTFE seat provides excellent valve tightness.
• Magnet coupling - real hermetic sealing.
