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 these particular refrigerants.

Function

See Design and material
drawings for additional details
on the following pages

EVR solenoid valves are designed on two different
principles:

1. Direct operation

2. Servo operation

1. Direct operation (NC)

EVR 2 – EVR 3 are direct operated. The valves open
directly for full flow when the armature (3) moves
up into the magnetic field of the coil.

This means that the valves operate with a minimum
differential pressure of 0 bar.

The seat plate is fitted directly on the armature (3).

Inlet pressure acts from above on the armature and
the valve plate. Thus, the inlet pressure and spring
force act to close the valve when there is no current
in the coil.

2. Servo operation (NC)

EVR 4 – EVR 22 are servo operated with a "floating"
diaphragm (4). The pilot orifice of stainless steel
is placed in the center of the diaphragm. The seat
plate is fitted directly to the armature (3). When
there is no current in the coil, the main orifice and
pilot orifice 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
is drawn up into the magnetic field and opens the
pilot orifice. This relieves the pressure above the
diaphragm, i.e. the space above the diaphragm
becomes connected to the outlet side of the valve.

The differential pressure between inlet and outlet
sides then presses the diaphragm away from the
main orifice and opens it for full flow. Therefore a
certain minimum differential pressure is necessary
to open the valve and keep it open. For EVR 4 – EVR
22 valves the minimum differential pressure for
safe operation is 0.03 bar.

When the current is switched off, the pilot orifice is
closed. Via the equalization holes in the
diaphragm, the pressure above the diaphragm
rises to the same value as the inlet pressure and the
diaphragm closes the main orifice.

EVR 25, EVR 32 and EVR 40 are servo operated
piston valves. The servo piston (16) with sealing
face closes against the valve seat by means of the
differential pressure between inlet and
outlet side of the valve and the force of the
compression spring. When the coil is switched on,
the pilot orifice opens. This relieves the pressure on
the piston spring side of the valve. The differential
pressure will then open the valve. The minimum
differential pressure for safe operation is 0.2 bar.

EVR (NO) has the opposite function to EVR (NC), i.e.
it is open with de-energized coil.

EVR (NO) is available with servo operation only.

3. Bi-flow operation with EVRC

EVRC is a servo operated solenoid valve with a
special diaphragm with built-in non-return valve.
The valve is for use in liquid lines in refrigeration
plants.

EVRC allows flow in both directions and can be
used in liquid lines in refrigeration plants with hot
gas or gas defrost.

During the refrigeration period EVRC works as
a normal solenoid valve, while during defrost it
allows the condensed liquid to return to the liquid
manifold.

During the defrosting period the coil for EVRC must
be energized.

4. Manual stem operation for EVR 6 - EVR 25 NC

EVR 6 - EVR 25 NC are available with optional
manual stem operation to manually force the
NC valve open when the coil is de-energized.

The protective cap should be removed and the
manual stem (12) should be rotated until the valve
is fully open. It takes approx. 6 cycles from fully
closed, to reach the fully open position.

After manual operation is completed, the valve
should manually be closed again and the protective
cap mounted.

Alternatively, all EVR NC and NO valves can be
manually operated by removing the coil and force
the valve open or closed by using a solenoid valve
tester (permanent magnet) code no. 018F0091.
