Pilot operated servo valve
Type ICSH 25-80

2 step opening of hot gas lines for defrosting

ICSH dual position solenoid valve belongs to
the ICV family and consists of an ICV housing,
an ICS insert together with an ICSH top cover
with 2 EVM normally closed solenoid pilots
installed in the top cover.

ICSH is used in hot gas lines for the opening of
hot gas defrost ow to the evaporator in 2
steps. Both steps are activated by a controller or
a PLC energizing the magnetic coils in a time
delay sequence.

Step 1 (approx. 20% of full ow) is to allow a
smooth pressure build-up in the evaporator,
while the subsequent step 2 opens the ow to
100% to get the full defrost capacity.

The ICSH is designed for large industrial
refrigeration systems with ammonia,
uorinated refrigerants or CO2.

The ICSH features 2 conguration options,
which is established at site.

First option is dependent conguration, which
secures that step 2 can never open unless step
1 has been mechanically activated.

Second option is independent conguration
that allows step 2 to open disregarding step 1.
By choosing the independent option attention
should be paid to the risk of liquid hammering
in case the step 1 for any reason is disregarded.

Function

Figure 1: Dependent conguration

Figure 2: Independent conguration

Figure 3: Supply ow

The ICSH is designed for a 2 step opening of the hot gas ow for the evaporator defrost. Step 1 (20% capacity) is
intended for a smooth pressure build up in the evaporator - step 2 will open for full capacity.

The valve is pilot controlled by 2 standard EVM Normally Closed valves and the 2 EVM’s are controlled by an external
controller like PLC.

The external controller simply needs to activate the 2 EVM coils in a sequence with a certain time oset.

The time oset depends on the specic conditions around the ICSH and must be determined at site.

The opening of the ICSH is done by a pressure dierence between the inlet pressure P1 and the outlet pressure P2,
and for the main valve to open fully, a Δp of 0.2 bar (2.9 psi) is needed.

Figure 4: Supply ow

Pilot operated servo valve, type ICSH 25-80

The ICSH main valve can be congured into 2 dierent congurations: Dependent or Independent.

The Dependent setup (Figure 1: Dependent conguration) means that fully open (step 2) can only be performed if
step 1 is performed successfully. If step 1 for some reason fails, the valve will not open at all.

The matching control program should, in this case, be to activate step 1 coil followed by activation of step 2 coil.

Dependent setup is done by installing the 2 EVM’s in Port SI (step 1) and Port SII (step 2), and blanking o the P port
with Blanking plug A+B.

The Independent setup (Figure 2: Independent conguration) involves the option to force step 2 to open
independent of the result of step 1.

The matching control program should also in this case be to activate step 1 coil followed by activation of step 2 coil.
When step 2 is activated the full ow will immediately be started.

ATTENTION:



A risk of liquid hammering in the system may appear.

Independent setup is done by installing the 2 EVM’s in Port SI (step 1) and Port P (step 2), and blanking o the SII
port with Blanking plug A+B.

The internal channel structure allows in both congurations a direct ow to the step 1 EVM. By activating step 1 the

ow will continue through the spring guided needle that is resting on the top of the piston (see Figure 3: Supply

ow).

The ow will build up a pressure on top of the piston, which will start moving down i.e. start open the main valve.
The spring guided needle follows the pistons movement downwards and after a predened distance the needle
reaches its stop position, where the needle closes the supply ow (see Figure 4: Supply ow).

The bleed hole in the piston top will allow a certain ow out of the pressurized chamber thus enable the piston to
move upwards, but any movement of the piston is now being controlled by the needle that compensates by
opening the supply ow.

The needle will balance the supply/bleed ows and keep the piston at this position. Step I ow - equivalent to
approx. 20% of capacity - has now been established.

After a predetermined period of time the step II coil is activated.

In dependent set-up further ow can only reach the step II EVM if step I EVM is open (working properly). In
independent set-up further ow can reach the step II EVM regardless the status of step I.

Once ow is passing through step II EVM it continues to the top of the piston and moves the piston to full open
position.

For both congurations the valve will close and stay closed when both coils are de-energised.

The closing is achieved by drainage through the bleed hole.

ICSH is including a manual opener like all the valves in the ICV family. The operation of the opener is done by
turning the spindle clockwise (opening the valve) or counterclockwise (closing the valve).



ATTENTION:

Attention should be paid to the maximum torque applied to the spindle when turning: Never exceed 15 Nm to the
spindle in any direction.

Controller and Wiring

The 2 steps need to be activated from a PLC in a time delay sequence. The time delay itself must be determined on
site since local conditions are decisive.

The wiring from the controller to the 2 coils can be done by either one or two cables.

the gure to the right.

Two cable layout requires two subsequent output signals from the PLC.

Applicable to HCFC, HFC, R717 (Ammonia) and R744 (CO2).

New refrigerants

Danfoss products are continually evaluated for use with new refrigerants depending on market requirements.

When a refrigerant is approved for use by Danfoss, it is added to the relevant portfolio, and the R number of the
refrigerant (e.g. R513A) will be added to the technical data of the code number. Therefore, products for specic
refrigerants are best checked at store.danfoss.com/en/, or by contacting your local Danfoss representative.

The ICSH Concept

The ICSH concept is developed to highest exibility of direct welded connections. For valve sizes ICV 25 – ICV 65 a
wide range of connection sizes and types is available.

The direct welded (non-anged) connections secure low risk of leakage.

There are ve valve bodies available (ICSH 80 makes use of ICV 65 housing).

Figure 6: Valve bodies

Design (valve)

The ICSH valves are approved in accordance with the European standard specied in the Pressure Equipment
Directive and are CE marked.

ICV PM anged valve housings

ICV PM anged valve housings can replace the PM valves on already installed refrigeration systems.

Pressure range

The ICV PM valve housing is designed for a max. working pressure of 28 bar / 406 psig and therefore a suitable
replacement for PM valves in the service market. They also oer the same drop-in dimensions as the PM valves.

ICV (H)A4A anged valve housings can replace the (H)A4A valves on already installed refrigeration systems.

Pressure range

The ICV (H)A4A valve housing is designed for a max. working pressure of 28 bar g / 406 psig and therefore a suitable
