Solenoid valves
Type EVU for fluorinated refrigerants
EVU solenoid valves are designed to fit into
compact refrigeration systems. Available in direct
and pilot operated versions, they can be applied in
liquid, suction, and hot gas lines with fluorinated
refrigerants.
EVU solenoid valves can be used in many different
refrigeration systems and are specially designed
for:
y commercial refrigeration systems
y refrigeration appliances
y liquid coolers
y ice cube machines
y mobile refrigeration systems
y heat pump systems
y air conditioning units
EVU valves are available in straightway
or angleway design. All valves are semi hermetically
sealed and are not serviceable. The standard coil is
available with 3-core cable connection, DIN plug
and 0.25 US spade.
EVU valve bodies and coils are ordered separately
in industrial pack.
Features y Compact construction small dimensions,
low weight for both valve and coil.
y Semi-hermetic construction. Metallic sealing
between armature tube and valve body. Bimetal
connections to the brass
housing Benefits:
– high strength of joints and high
vibration resistance
− maximum external tightness within
the whole temperature and pressure
operation range
y Bimetal connections simple, fast soldering
without the need of wet cloth or
refrigration pliers.

y Direct and servo operated mini piston compact
solenoid valve.
y Universal application for
− liquid, suction, and hot gas applications
− reduced power consumption
y Simple and fast mounting of coil
− clip-on/off
y Small encapsulated coils with long life time
under extreme conditions.
y Refrigerants:
R744, R22/R407C, R404A/R507, R410A,
R134a, R407A, R23.
For other refrigerants, please contact Danfoss.
y Large MOPD range − up to 36 bar.

Correction factors
When liquid temperature tl ahead of the expansion
valve is other than 100°F, adjust the table capacities
by multiplying them by the appropriate correction
factor found in the following table.
