The valve train of the
Future since 2005
The ICF valve station is an innovative solution
that provides the full functionality of a
conventional valve station in a single compact
unit.
Eliminate project bottleneck:
Conventional valve stations of six or more
individual components and up to twelve welds.
ICF means two welds directly at the job site
Down time during service is reduced to a fraction
compared to conventional valve trains. The
unique design of the ICF ensures a quick pump
down and faster access to valve modules.
The ICF valve is a compact valve train ready for
the jobsite.
This solution provides you with a variety of
benefits:
Designed for Industrial Refrigeration
Supplied fully assembled. No need to
disassembly prior to installation under normal
welding procedures
Standard side ports to fit service valves,
pressure transmitters, sight glasses.
Applicable to all common non flammable
refrigerants including R744 and R717.
Direct Weld Connections (No leaks through
flanges)
Compact design, faster service
Available with different connection types
including ANSI and DIN, Socket weld
High capacities low pressure drop
Low weight design

Sizing through CoolSelector provides fast and
accurate selection while obtaining performance
information based on operating conditions.
All standard configuration are available in the
software. However, custom configurations of the
ICF is possible. Contact you local representative
for availability.
CAD symbols 2D & 3D
When designing new units and applications, CAD
drawings are essential for getting the job done as
precisely and easily as possible. Danfoss provides
low file-size CAD symbols for all standard ICF
code numbers. These CAD symbols make it
easy for all design engineers to make quick and
compact designs.

(Liquid make up)
The ICF valve station offers a unique solution for
liquid injection to separator. For this application
the ICF (20-40)-6-5 is recommended.
Using the ICF (20-40)-6-5 the valve provides you
with an advanced ICM motor control valve with a
solenoid in front. It is delivered with a sight glass
in the side port of the valve housing.
For fail safe operation this type of ICF is equipped
with a ICFE solenoid valve in front of the ICM
motor operated valve.
The ICF consist of the following modules:
The ICF 20-6-5 is available in versions A, B and C,
referring to the capacity of the electronic motor
valve. ICF (25-40)-6-5 is available in version A.
