Solenoid valves type EVR 2 40 NC / NO

Solenoid valves type EVR 2 40 NC / NO
Solenoid valves
type EVR 2 → 40 − NC / NO
Introduction
Features
EVR is a direct or servo operated solenoid valve
for liquid, suction, and hot gas lines with
fluorinated refrigerants.
EVR valves are supplied complete or as separate
components, i.e. valve body, coil and flanges, if
required, can be ordered separately.
• Complete range of solenoid valves for
refrigeration, freezing and air conditioning plant
• Flare connections up to 5/8 in.
• Supplied both normally closed (NC) and
normally open (NO) with de-energized coil
• Wide choice of coils for a.c. and d.c.
• Suitable for all fluorinated refrigerants
• Designed for media temperatures up to 105°C
• Solder connections up to 2 1/8 in.
• Extended ends for soldering
make installation easy
It is not necessary to dismantle the valve
when soldering in.
• EVR are also available with flange
connections
• MOPD up to 25 bar with 12 W coil

The kv value is the water flow in m3/h at a pressure drop across valve of 1 bar, ρ = 1000 kg/m3.
MOPD for media in gas form is approx. 1 bar greater.
EVR (NO): 21 bar.
EVR (NO): 19 bar.
13 bar, if d.c. coils is used for the a.c. version of EVR 20 and 22.
Rated liquid and suction vapour capacity is based on evaporating temperature te = −10°C, liquid temperature ahead of valve tl = +25°C, and
pressure drop in valve ∆p = 0.15 bar.
Rated hot gas capacity is based on condensing temperature tc = +40°C, pressure drop across valve ∆p = 0.8 bar, hot gas temperature th = +65°C, and
subcooling of refrigerant ∆tsub = 4 K.

When sizing valves, the plant capacity
R 22, R 134a 0.76
must be multiplied by a correction
R 404A
0.70
factor depending on liquid temperature
tl ahead of valve/evaporator.
When the corrected capacity is known,
the selection can be made from the table.

Hot gas defrosting
With hot gas defrosting it is not normally possible
to select a valve from condensing temperature tc
and evaporating temperature te. This is because
the pressure in the evaporator as a rule quickly
rises to a value near that of the condensing
pressure. It remains at this value until defrosting
is finished.
In most cases therefore, the valve will be
selected from condensing temperature tc and
pressure drop ∆p across valve, as shown in the
example for heat recovery.
Heat recovery
The following is given:
Refrigerant = R 22
Evaporating temperature te = −30°C
Condensing temperature tc = +40°C
Hot gas temperature ahead of valve
th = +85°C
Heat recovery condenser yield Qh = 8 kW
The capacity table for R 22 with tc = +40°C gives
the capacity for an EVR 10 as 8.9 kW, when
pressure drop ∆p is 0.2 bar.
The correction factor for te = −30°C is given in the
table as 0.94.
The correction for hot gas temperature
tc = +85°C has been calculated as +4% which
corresponds to a factor of 1.04.
Qh must be corrected with factors found:
With ∆p = 0.2 bar is
Qh = 8.9 × 0.94 × 1.04 = 8.7 kW.
With ∆p = 0.1 bar, Qh becomes only
6.3 × 0.94 × 1.04 = 6.2 kW.
An EVR 6 would also be able to give the required
capacity, but with ∆p at approx. 1 bar. The EVR 6
is therefore too small.
The EVR 15 is so large that it is doubtful whether
the necessary ∆p of approx. 0.1 bar could be
obtained. An EVR 15 would therefore be too large.
Result: An EVR 10 is the correct valve for the
given conditions.

EVR 10 (NO)
EVR 32 and 40 (NC)
EVR solenoid valves are designed on two
different principles:
1. Direct operation
2. Servo operation
1. Direct operation
EVR 2 and 3 are direct operated. The valves
open direct for full flow when the armature (16)
moves up into the magnetic field of the coil.
This means that the valves operate with a min.
differential pressure of 0 bar.
The teflon valve plate (18) is fitted direct on the
armature (16).
Inlet pressure acts from above on the armature
and the valve plate. Thus, inlet pressure, spring
force and the weight of the armature act to close
the valve when the coil is currentless.
2. Servo operation
EVR 6 → 22 are servo operated with a "floating"
diaphragm (80). The pilot orifice (29) of stainless
steel is placed in the centre of the diaphragm.
The teflon pilot valve plate (18) is fitted direct to
the armature (16).
When the coil is currentless, the main orifice and
pilot orifice are closed. The pilot orifice and main
orifice are held closed by the weight of the
armature, the armature spring force and the
differential pressure between inlet and outlet
sides.
Catalogue RK.00.H5.02 - Page 121
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 6 → 22 valves this differential pressure
is 0.05 bar.
When current is switched off, the pilot orifice
closes. Via the equalization holes (73) in the
diaphragm, the pressure above the diaphragm
then rises to the same value as the inlet
pressure and the diaphragm closes the main
orifice.
EVR 25, 32 and 40 are servo operated piston
valves. The valves are closed with currentless
coil. The servo piston (80) with main valve plate
(84) closes against the valve seat (83) by means
of the differential pressure between inlet and
outlet side of the valve, the force of the
compression spring (76) and possibly the piston
weight. When current to the coil is switched on,
the pilot orifice (29) 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 needed for
full opening of the valves is 0.07 bar.
EVR (NO) has the opposite function to EVR (NC),
i.e. it is open with de-energised coil.
EVR (NO) is available with servo operation only.
