Danfoss valves for the ecient control
of heating and cooling coils
The New ETS Colibri
Ensures that you get the optimal
superheat ow and wider applicable
range and exibility in partial load
operation, suiting the exact capacity
demands of a refrigeration system.
Key benets
• Low weight and compact design
• Fast opening/closing
• Hermetic design
NRV check valves
Can be used for liquid, suction and
hot gas lines in refrigeration and air
conditioning plants with uorinated
refrigerants. NRV and NRVH can
be supplied with are and solder
connections, which can provide
exibility in the use of check valves.
Key benets
• Maximized system eciency with minimized
pressure drop across the valve
• Laser welded components reduce
possibility of leaking and the valve
seat design ensures low noise during
opening/closing
• High-quality materials ensure minimum
maintenance costs over the life of the unit

The dierential pressure controllers
eliminate pressure variations
and provide optimum operating
conditions. Good working conditions
for control valves increase the quality
and precision of the temperature
control, even for low ow
requirements. The connected system
is protected against pressure surges,
uctuations, cavitation and noise.
Key benets
• Flow controllers with an integrated
control valve have multiple
functions integrated into a single
product – a motorized control
valve, ow limitation and xed
dierential pressure controller.
With three functions combined
in one valve body, it signicantly
saves installation space
• Medium temperature up to 150°C
• Adjustable ow restrictor

GBC ball valves
Are manually operated shut-o
valves suitable for applications where
bidirectional ow is a requirement.
They are approved for applications
in liquid, suction, and hot gas lines
in refrigeration and air conditioning
systems.
Standard GBC valves may be used
in applications using high pressure
refrigerants, including R410A, and
GBC bidirectional ball valves can be
delivered with or without external
access port.
Key benets
• Multiple layers of sealing and laser
welding ensure high quality and a
long lifetime
• Our full port design allows for high
ow/low pressure drops across the
valve
• Bi-ow, i.e. valve orientation is
irrelevant
