Solenoid valves
Type EVU for fluorinated refrigerants

EVU solenoid valves are designed to fit into
compact refrigeration systems. Available in direct
and servo 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.

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.

• UL Recognized Component (Canadian and US)

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.

 Cv value is the water flow in [gal / min] at a pressure drop across valve p = 1 psi, ρ = 10 lbs / gal

2

 MOPD for media in gas form is approximately 14 psi greater

 For coil 208 – 240 V, 60 Hz, MOPD is 250 psi

MOPD (Max. Opening Pressure Differential) is measured with highest media and ambient temperature and
15% below nominal voltage

Direct operated

EVU 1 is direct operated. The valve opens directly
for full flow when the armature (9) moves up into
the magnetic field of the coil.

This means that the valve can operate at 0 bar
differential pressure. Thus, inlet pressure and spring
force act to close the valve when the coil is
currentless.

Servo operated

EVU 2 - 8 are servo operated piston solenoid valves.
The servo piston principle results in a fast
operating and compact valve that is able to open
against a high differential pressure. The valve
closes rather soft, because the pilot system does
not fully close before the main orifice has closed.
This minimizes liquid hammer.

When the coil is currentless, the main orifice, seat
plate (12) and pilot orifice (on the pilot plate (11))
are closed. The pilot orifice and main orifice are
held closed by the armature spring force and the
differential pressure between inlet and outlet sides.

Servo operatedDirect operated

When current is applied to the coil, the armature (9)
is drawn up into the magnetic field and thus lifts
the pilot plate (11) and opens for the pilot orifice so
that the de-energising of the servo chamber (A)
starts and the pressure is relieved to the level of the
outlet side. As the inlet pressure that acts on the
bottom of the piston (13) now is higher than the
pressure in the servo chamber (A), the piston is
moved upwards and lifts both the pilot plate (11)
and the seat plate (12). When the seat plate is lifted,
the main orifice opens for full flow.

Therefore a minimum differential pressure of 0.02
bar is necessary to open the valve and keep it open.

When the current to the coil is switched off, the
spring (8) forces the armature (9) down towards the
pilot plate (11). The pressure in the servo chamber (A)
increases and the piston will no longer be able to
hold the seat plate (12) in lifted position, by which the
main orifice closes. The armature (9) continues its
downwards movement until the pilot orifice on the
pilot plate (11) is fully closed.
