-40 °C / -40 °F – 50 °C / 122 °F
MOPD operating range
EVUL 1 – 8: 0.02 - 36 bar / 0.29 - 522 psi
MOPD is measured with highest media and
ambient temperature and 15% below nominal
voltage.
Special note for R290:
The EVUL is validated in accordance to ATEX,
ISO 5149, IEC 60335, and UL. Ignition risk is
evaluated in accordance to ISO 5149 and IEC
60335.
See safety note at the bottom of this page.
Max. working pressure
MOPD (Max. Opening Pressure Differential) for
media in gas form is approximately 0.97 bar
greater.
Kv value is the water flow in m3 / hour at a
pressure drop across valve ∆p = 1 bar,
ρ = 1000 Kg / m3.
Cv value is the water flow in [gal / min] at a
pressure drop across valve Δp = 1 psi,
ρ = 10 lbs / gal
The EVUL can be applied on systems with R290 as the working fluid.
For countries where safety standards are not an indispensable part of the safety system Danfoss
recommends the installer gets a third party approval of any system containing flammable refrigerant.
Note: please follow specific selection criteria stated in the datasheet for this particular refrigerants.

If coils are below IPx5, they must be protected
Special note for R290:
The EVUL coil (IP65/67) is validated in accordance
to ISO 5149, IEC 60335 (ref. IEC/EN 60079-15).
Ignition risk is evaluated in accordance to ISO
against ultraviolet, moisture and major impact,
especially the connection of coils.
Always Install a fuse ahead of the coil:
rated current: two times of rated current,
time lag: medium, to avoid short circuit.
5149 and IEC 60335 (ref. IEC/EN 60079-15).
See safety note at the bottom of this page.
The coil used in an area of not more than
pollution degree 2.
Please make sure that there is no spark, arc on
the spade connection during the application.
Follow the installation guide to mount the coil
correctly, and apply o-ring for sealing to prevent
moisture penetrating inside the coil.

- pressure drop p across the valve.
Capacities are based on a hot gas temperature superheated 40 °F above condensing temperature (th = tc 40 °F).
For each additional 10 °F of superheat above 40 °F, the table capacities must be reduced by 1%.
When the valve is used in a hot gas defrost circuit, evaporator temperature affects the capacity.
When the evaporator temperature differs from 40 °F, adjust the table capacities by multiplying them
by the appropriate correction factor found in the following table.
The table values refer to evaporator capacity and are given as a function of:
- evaporating temperature te,
- pressure drop p across the valve.

Function
Servo operated
EVUL 1 – 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 (8) and pilot orifice (on the pilot plate (7))
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.
When current is applied to the coil, the armature
(6) is drawn up into the magnetic field and thus
lifts the pilot plate (7) 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 (9) now is
higher than the pressure in the servo chamber
(A), the piston is moved upwards and lifts both
the pilot plate (7) and the seat plate (8).
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 (5) forces the armature (9) down towards
the pilot plate (7). The pressure in the servo
chamber (A) increases and the piston will no
longer be able to hold the seat plate (8) in lifted
position, by which the main orifice closes. The
armature (6) continues its downwards movement
until the pilot orifice on the pilot plate (7) is
fully closed.
Note:
Danfoss recommends that a suitable filter or
filter drier (max. size of 40 – 50 µm) is installed
ahead of each solenoid valve to keep scale,
solder material and other foreign dirt and
particles out of the valve.
Note:
By using the valve for oil return application please contact Danfoss.
