Solenoid valve
Types EVR 2 - EVR 40
Danfoss | DCS (rja) | 2016.01 DKRCC.PD.BB0.A8.22 | 1
Features y A complete range of solenoid valvesfor refrigeration, freezing and airconditioning systems
y Normally closed (NC) and normally open (NO)versions available
y AC and DC coils are interchangeable on allvalve body versions
y Use with any fluorinated refrigerant
y Designed for media temperatures up to 220 F
y Flare connections up to 5/8in
y Solder connections up to 2 1/8in
y Solder versions have extended connections;there is no need to dismantle the valvewhen soldering
EVR is a direct or servo operated solenoidvalve for liquid, suction, and hot gas lines withHCFC and HFC refrigerants.
EVR valves are supplied complete or as separatecomponents, i.e. valve body, coil and flanges, ifrequired, can be ordered separately.
Approvals UL listed, file MH 7648 Note:These approvals are only recognized when oneof the EVR series of solenoid valves found inthis leaflet is combined with a GP generalpurpose coil.

Technical data
1)Cvvalue is the water flow in [gal/min] at a pressure dropacross valve p = 1 psi. = 10 lbs/gal
2)MOPD (Max. Opening Pressure Differential) for media in gasform is approximately 14 psi greater
3)EVR (NO): 300 psig4)EVR (NO): 275 psig

Capacities are based on:Liquid temperature tl= 100 FEvaporatingtemperature te= 40 FSuperheattemperature (te+ 10 F) = 50 F
Metric conversions1 psi = 0.07 bar5/9(t1F - 32) = t2C1 TR = 3.5 kW

The table capacity should be corrected by thecorresponding factor as:
Qtable xfliquid = Qo
Step 1:Determine the correction factor for liquidtemperature. From the correction factor tablefound on page 8, a liquid temperature of 90 Fcorresponds to a factor of 1.05.
Step 2:
Correct the required valve capacity.This is done by dividing the evaporatorcapacity by the liquid correction factor.Q
corrected= 10/1.05 = 9.5 TR
Step 3:Select the appropriate capacity tableand choose the first valve whose capacityis greater than or equal to Q
correctedat the required
pressure drop. Using the R134a liquid capacitytable found on page 8, the EVR 15 is selectedas it has a capacity of 12.5 TR at a p = 2 psi.

(required valve capacity)
The table capacity should be corrected by thecorresponding factor as:
Qtable xfliquid xfsuperheat = Qo
Step 1:Determine the correction factor for superheatahead of the valve by increasing the requiredvalve capacity by 2% for each 10 F of actualsuperheat above the table rated value of 7 F.
In the example. a superheat of 17 F correspondsto a 10 F increase above the table valuewhich is equivalent to a superheatcorrection factor of 0.98.
Step 2:Determine the correction factor for liquidtemperature. From the correction factor tablefound on page 13, a liquid temperature of 90 Fcorresponds to a factor of 1.05.
Step 3:Correct the required valve capacity. This is doneby first multiplying the evaporator capacity bythe superheat correction factor and thendividing it by the liquid correction factor.
Qcorrected= 10/0.98/1.05=9.7
Step 4:Select the appropriate capacity tableand choose the first valve whose capacityis greater than or equal to Qcorrectedat the required evaporating temperatureand pressure drop. Using the R134asuction vapor capacity table foundon page 13, the EVR 40 is selectedas it has a capacity of 14.75 TRat t
e= 30 F and p = 3 psi.
Valve selection exampleNote:When selecting the appropriatesolenoid valve, it is easier to convert the actualrequired capacity to that of the rated capacitieslisted in the tables.
This is done by utilizing various correctionfactors in the selection process. The followingexamples illustrate how this is done.

Valve selection example(continued)
Hot gas line solenoid valve selection exampleWith hot gas defrost, pressure in the evaporatorquickly rises to a value near that of thecondensing pressure and remains thereuntil the defrost cycle has been completed.
Therefore. when selecting valves for hot gasapplications, sizing is based primarily on the
condensing temperature tcand the pressuredrop Dpacross the valve.
Example (with heat recovery)Refrigerant: R134aEvaporator temperature: te= 0 FCondensing temperature: tc= 100 FHot gas temperature ahead of valve: t h= 180 FMaximum allowable pressure drop acrossvalve: p = 5 psiOutput of heat recovery condenser: Qh= 15 TR(required valve capacity)
The table capacity should be corrected by thecorrespondig factor as:
Qtable xfevaporator xfsuperheat = Qo
Step 1:Determine the correction factor for hot gas
temperature (th= tc+ 40 F) by increasing therequired valve capacity by 1% for each 10 Fof actual superheat above the table ratedsuperheat value of 40 F.In the example, an actual hot gas temperatureof 180 F is 40 F higher than the calculated tablevalue of (th= tc+ 40 F = 140 F). This is equivalentto a hot gas correction factor of 0.96.
Step 2:Determine the correction factor for evaporatortemperature. From the correction factor tablefound on page 19 an evaporator temperatureof 0 F corresponds to a factor of 1.09.
Step 3:
Correct the required valve capacity. This is doneby first multiplying the heat recovery capacity bythe hot gas correction factor and then dividing itby the evaporator correction factor.Qcorrected= 15 /0.96/1.09=14.3
Step 4:Select the appropriate capacity table and choosethe first valve whose capacity is greater thanor equal to Qcorrectedat the required condensingtemperature and pressure drop. Using the R134ahot gas capacity table found on pages 19 and 20,the EVR 32 is selected as it has a capacity of21.8 TR at tc= 100 F and p = 5 psi.

EVR solenoid valves are based on two differentdesign principles:1. Direct operation2. Servo operation
1: Direct operationEVR 2 and EVR 3 are direct operated. The valvesopens to admit full flow when the armature (16)is moved up into the magnetic field of the coil.
The valves operates with a minimum differentialpressure of 0 psi.
The valve plate (18) is fitted directly tothe armature (16).Inlet pressure and spring force act to close thevalve when the coil is de-energized.
2a:EVR 4 EVR 22 are servo-operated with afloating diaphragm (80). The pilot orifice (29)is located in the center of the diaphragm.
The pilot valve plate (18) is fitted directly to thearmature (16).When the coil is de-energized, the valve port andpilot orifice are closed and the inlet pressure actsboth above and below the diaphragm.
The valve port and pilot orifice are kept closed bythe armature spring force and the differentialpressure between inlet and outlet sides.When current is applied to the coil, the armatureis pulled up into the magnetic field and the pilotorifice opens. This relieves pressure above thediaphragm because the space above it becomesconnected to the outlet side of the valve.
The differential pressure between inlet andoutlet presses the diaphragm away from thevalve seat (83) and the valve opens to admit fullflow. A minimum differential pressure (0.7 psi forEVR 4 EVR 22) is necessary to open the valveand keep it open.When the coil is de-energized, the pilot orifice
closes. Then. via the equalizing port (73)the pressure above the diaphragm rises to thesame value as the inlet pressure, which results inthe valve port being closed by the diaphragm.
EVR 6 EVR 15, NO, function in a manneropposite to the NC valves; they are open whenthe coil is de-energized.Normally open (NO) EVR valves are available withservo operation only.
Note:The drawings are only representative.

2b. Servo operation of EVR 25 EVR 40EVR 25. EVR 32 and EVR 40 are servo-operatedpiston valves.
The valves are closed when the coilis de-energized. In operation. EVR 25 is the sameas for EVR 4 EVR 22. but the design is different.
The pilot unit is located in the cover and theservo unit is a piston (80) with a cast ironpiston ring.
For EVR 25 EVR 40, piston (80) and valve plate(84) will close against the valve seat (83) due tothe differential pressure between inlet
and outlet plus the force from the returnspring (76).When the coil is energized, the pilot orifice (29)is opened and pressure on the spring sideof the piston is relieved. The pressure differentialnow opens the valve. The minimum differentialrequired to keep the valve fully open is 1 psi.
