Installation
Refrigerants
The ICMTS 50/80 is specically designed for
high pressure R744 applications. The valve is
only recommended for use in closed circuits. For
further information, please contact Danfoss.
Temperature range
Allowable TS: -60/+150 °C (-76/+302 °F)
Operation: -40/+50 °C (-40/+122 °F)
Ambient: -30/+50 °C (-22/+122 °F)
In systems with continuous media temperatures
above +50 °C (+122 °F) Danfoss recommend to
inspect the valve annually and replace the PTFE
valve seat if needed.
Pressure
The valves are designed for a max.
working pressure of 140 bar (2030 psig).
Function
ICMTS is a balanced valve which remains in its
position. The return function must be provided
by use of the actuator.
The ICMTS can be used in suction, liquid, hot gas
and liquid/vapour lines. The ICMTS regulates the
ow of the medium by modulation or the on/
o function, depending on the control impulse
to the actuator. Refer to the technical leaet for
details on design and regarding selections. The
ICMTS valve is designed for use with the ICAD
600A-TS actuator from Danfoss.
The ICAD 600A-TS actuator on the ICMTS ensures
compatibility with the regulators provided
by Danfoss plus a range of other controllers,
especially PLC controllers. A control signal from
a Danfoss controller or PLC will activate the
ICAD 600A-TS motor and, through a magnetic
coupling, rotate the spindle in the ICMTS to
make the cone change opening degree.
Valve sizes
ICMTS is available in sizes from
• ICMTS 50-A (Kv : 9,0 m3/h)
• ICMTS 80-A (K
v : 18 m 3/h)
• ICMTS 80-B (Kv : 27 m 3/h)
Installation
ICMTS + ICAD 600A-TS can be installed in
pipelines with the actuator pointing upwards
(g. 1) or in 45 °C angle to vertical up.
The motor can be mounted in any position
before locking it with the 3 Allen screws (g. 6,
pos. 2).
The ICMTS valve must be installed with the
arrow in the direction of ow. When installing
an ICMTS, refrigerant must not be allowed to
escape, and dirt must not be allowed to enter
the valve. The valve is designed to withstand
a high internal pressure. However, the piping
system should be designed to avoid liquid traps
and reduce the risk of hydraulic pressure caused
by thermal expansion. It must be ensured that
the valve is protected from pressure transients
like “liquid hammer” in the system.
ICMTS valves must not be mounted in systems
where the outlet side of the valve is open to
atmosphere. The outlet side of the valve must
always be connected to the system or properly
capped o, such as the case with a welded-on
end plate.
Welding or brazing (g. 3 & 4)
The top cover, complete with function module,
should be removed before welding or brazing to
prevent damage to O-rings and Teon (PTFE)
in the function module and to avoid getting
welding debris in the module. Be careful not to
damage the sealings and sealing surfaces and
make sure the complete bonnet is protected
from dirt and water while removed.
The internal surfaces and weld connections of
the enclosed ICMTS valve have been applied
with an anti-corrosion treatment. To maintain
the eectiveness of this anti-corrosion
treatment, it is important to ensure that the
valve is disassembled just prior to commencing
the welding / brazing process. In the event that
the function modules are to be left disassembled
for any length of time, please ensure that the
function modules are further protected by
placing in a polyethylene bag or by applying a
rust protection agent (e.g. refrigeration oil) on
the surfaces.
Only materials and welding methods,
compatible with the valve body material,
must be applied. The valve should be cleaned
internally to remove welding debris on
completion of welding and before the valve is
reassembled.
Avoid welding debris and dirt in the valve body
and the function module. The valve body must
be free from stresses (external loads) after
installation.
Brazing (g. 4)
When brazing, Danfoss recommends using Ag40
minimum 450 – 700 °C ller or better which are
suitable for the working pressure, and following
procedure observed (g. 4):
1. Remove top cover/insert
2. Clean connections with cleaning agent
3. Wrap around wet cloth
4. Apply ux on piping ends
5. Apply inert gas internal
6. Heat up piping
7. Braze with recommended brazing material
and within temperature range specied
8. Remove residual ux
Manual operation
A magnetic coupling can be used to rotate
the spindle manually if the actuator has been
removed. To make use of the manual operation,
a multi-function tool (optional) is used (see g. 7).
The code number for the multi-function tool is
027H0181.
Manual operation is also possible with the
actuator mounted on the valve and the power
supply connected to the actuator. If the signal
connections are wired to the actuator, it is
possible to use the manual operation function
built into the actuator electronics which allows
the motor to step in 1% increments meaning
that 100 steps will correspond to a fully open
valve. Please refer to the separate instruction
manual on ICAD to address the manual function.
Insulation
Insulating the valve and its actuator is only
necessary if an energy consideration in the
plant requires
this. Regarding the function of the
ICMTS + ICAD 600A-TS,
no insulation is necessary
when kept inside temperature limits.
Surface treatment and identication
The ICMTS valves are surface treated from
factory. If further corrosion protection is
required, the valves can be painted.
Note: Magnet coupling must be protected.
Precise identication of the valve is made via
the ID plate.
After welding, the external surface
around the connections of the valve body must
be protected to prevent against corrosion with a
suitable coating. When repainting the valve, it is
recommended to protect the ID plate.
Assembly
Remove welding debris and any dirt from pipes
and valve body before assembly. Use the manual
magnetic tool (g. 7) to achieve rotation through
the top. A small amount of refrigeration oil on
both O-rings can make the insert easier to install
into the valve body.
Tightening
Tighten the bonnet with a torque wrench, to
the values indicated in the table (g. 2). Please
note that the table (g. 2) containing maximum
torque must be adhered to and never exceeded.
ICAD 600-TS conguration
To work with ICMTS 50/80 the ICAD parameter
i26 Valve conguration shall be set to 3 (ICM 32).
Maintenance
Service
A precise service schedule cannot be given for
the valve as service intervals will depend on
operating conditions, i.e. how often the valve
operates and the amount of impurities and dirt
the system carries.
The ICMTS valves are easy to dismantle, and all
parts inside can be replaced by changing the
function module.
Do not open the valve while the valve is still
under pressure.
Be aware that the valve can be under pressure
from both sides and that the manual magnet
tool (g. 7) can be used to open the seat to
equalize pressure internally before removing the
top cover.
Before servicing the valve, isolate it from
the system. Drain CO liquid e.g. to above
5,2 bar to prevent large formation of dry ice
before evacuation to zero pressure. Check for
refrigerant pressure before unscrewing and
removing the top cover. If the at gasket (g. 6,
pos. 1)
or the O-ring sealing (g. 6, pos. 3) has
been damaged, it must be replaced using the
ICMTS inspection kit.
Replacement of the function module
- Remove the old module.
- Oil the O-rings (g. 6, pos. 3 & 4) on the new
module with a small amount of refrigeration oil.
The spindle inside the valve must not
be greased or oiled (g. 5).
Repair of the function module
The ICMTS 50/80 seat PTFE sealing can be
replaced using Danfoss repair kit.
1. Unscrew the 4 M4 Allen screws (g. 8)
2. Fasten the cylindrical assembly lower part in a
vise at the at surfaces and unscrew the upper
part with a wrench at the at surfaces (g. 8,
pos. 1 & g. 9)
