The ICM motorized valve is comprised of up to 4
components:
• the valve body – often referred to as the ICV body
because it is used for ICM motor valves, ICS pilot
operated valves and ICLX solenoid valves.
• the function module – the ow regulating part of
the valve
• the top cover – on the ICM 20 through 65, the
function module and top cover are one part
• the ICAD motor actuator – the “brains”of the
valve

ICM/ICAD overview The combinations of valve and actuator are as follows:
* ICAD 600, 900 and 1200 were discontinued at the end of 2014. ICAD 600A is a direct replacement of ICAD 600 and ICAD 1200A is a
direct replacement of ICAD 900 or ICAD 1200.

Note:
The outside edges of the
B66 cone has more of a
cylindrical shape compared
to the B cone which forms
more of a conical shape.
Identifying ICM sizes All ICM sizes except ICM 20 have a stainless steel
ID tag located around the valve stem on the top
cover which the ICAD mounts on. When the ICAD
is mounted it can be dicult to locate this. The
sticker on the valve body of the large valves states
ICV and the valve size because the body is shared
between the ICM motor valves, ICS pilot operated
valves and ICLX solenoid valves.
The ICV size is the same size as the ICM size which
is needed during programming. ICM 20 only has a
sticker on the side of the valve body to identify the
size.
If the sticker is missing the size can be identied by
the shape of the cone. The below gure shows how
to indentify the ICM 20 size by looking at the cone.

Dierences between 1st and
2nd generation ICAD motor
actuators
The 2nd generation ICAD was released in the
beginning of 2010. The part numbers on the
label for the 2nd generation start with 027H9…
and the 1st generation part numbers started with
027H12… The cables of the 1st generation were
mounted through cable glands located in the
plastic top whereas the 2nd generation has the
cables mounted on connectors located in the
aluminum body.
Note: The wire colors are dierent between the two
generations and the following is a table with the
dierences and pictures of old and new generation.

Installation

1. All ICM valves and ICAD motor actuators must
be installed in horizontal pipelines with the
motor actuator in an upright position.
2. Preparation of Valve Body
ICM 20 (3/4”) valves: both the integrated
bonnet/function module and the separate
valve seat must be removed from the valve
body prior to welding. To remove the
ICM20-A33 or ICM20-A valve seat use a 13mm
socket and to remove the ICM20-B66, ICM 20-B
or ICM20-C valve seat, use a 12 mm hex key.
- ICM 25 to 65 (1”to 2-1/2”) valves, the
integrated bonnet and function module
should be removed as shown in the gure.
- ICM 100 to 150 (4”to 6”) valves, the function
module and bonnet are separate pieces and
do not need to be removed prior to welding.
However, some form of arc welding should
beusedtoweldthevalveintothepipingand
care should be taken to protect the valve
stem from becoming contaminated.

Care should be taken to protect the ICM function module when it is removed and stored during
installation of valve body.
3. Weld the valve body in line making sure that the arrow on the valve body is pointing in the direction
of ow.
- For ICM 20 through 65, make sure that all debris is removed from valve body before bonnet/
function module is re-installed.
- For the ICM 20, make sure that the removable orice seat is re-installed in the valve body with the
small o-ring between the orice seat and the body. Use a 13mm socket to tighten the ICM20-A33 or
ICM20-A valve seat to a torque of 6.5 ft-lbs (9 N-m). Use a 12 mm hex key to tighten the ICM 20-B66,
ICM20-B or ICM20-C valve seat to a torque of 1.5 ft-lbs (2 Nm).
DO NOT OVERTIGHTEN THE REMOVABLE SEAT.
Make sure that the bonnet gasket is installed and in good condition.
- For the ICM 25 through ICM 65, check that the two o-rings are installed on the function module and
that the gasket located on the top of the valve body is installed and all are in good condition.
A light coating of refrigerant oil on the bonnet o-rings and the cover gasket will facilitate assembly
of the valve.
4. Install the bolts and torque to the following specications:
5. Install the ICAD Motor on the ICM valve:
The ICM valve must not be in its full opened position while the ICAD motor is calibrated with the valve
(at a later step). Therefore, if the opening degree of the ICM valve was changed from the factory
setting, it should be set to an opening degree between 0% and 75% using the manual magnet tool.
To easily ensure correct positioning, turn the manual tool counter-clockwise until it is clear that it
cannot be turned any further.
- Make sure that the ICM adapter/valve stem and inner ICAD magnets are completely dry and free
from any debris.
- For applications below freezing, the ICM adapter O-ring (position 2c in the diagram on page 5)
must be removed and Molycote G 4500 grease (supplied with ICAD motor) needs to be applied in
the O-ring groove on the adapter and on the O-ring before it is re-installed on the ICM adapter.
The Molycote grease ensures a good seal between the ICAD motor and the ICM adapter to prevent
moisture from entering the ICAD magnets.
- Place the ICAD motor on the valve stem.
- Push the ICAD motor completely down to the identication ring on the valve stem. Using a 2.5 mm
hex key, tighten the set screws evenly so the ICAD motor is centered on the ICM valve stem.
Torque the set screws to approximately 3 Nm (2.5 ft-lbs).
