Electric expansion valve for R744 (CO2)
Type AKVH
AKVH are electrically operated expansion
valves designed for refrigerating plants using
R744 refrigerant.
The AKVH valves are normally controlled by a
controller from Danfoss’ range of
ADAP- KOOL® controllers.
The AKVH valves are supplied as a component
program, as follows:
• Separate valve.
• Separate coil with junction box or conduit
hub.
• Spare parts in the form upper part, orice
and lter.
The orice assembly is replaceable.
The AKVH 10 valves cover a capacity range
from 0.1 TR to 3 TR in refrigeration applications
and 0.2 TR to 6.25 TR in freezing applications.
Features
y For R744 refrigerant.
y The valve requires no adjustment.
y Wide regulation range.
y Replaceable orice assembly.
y Normally closed, solenoid tight expansion
valve.
y Wide range of a.c. coils.
y Enables energy saving minimum stable
superheat and adaptive defrost algorithms.
y Provides excellent distribution and oil return
due to turbulent ow.
