Identiﬁcation of the valve:

NOTE: This mounting guide covers

EV220T variants with threaded or

hose outlet.

Valve type, code number, production

date (wwy; eg. 372 / ‘week 37, year

2012’) and country of origin is

printed on the valve armature tube.

Mounting the valve:

1. Clean the pipe system before

mounting the valve and make

sure it is properly aligned.

2. Make sure that the application

pressure does not exceed 10 bar.

3a+ Danfoss recommends mounting

3b. a ﬁlter in front of the valve or

using the available built-in ﬁlter.

This will prevent impurities from

entering the valve and causing

functional problems or damage.

4. The valve can be mounted at

any angle.

5. The arrows on the valve body

must point in the direction of

the ﬂow. The arrows can be

found on the side, bottom and

top of the valve body.

6a. If needed the valve can be

mounted using the supplied

bracket. The ﬂat surface of the

bracket must face the inlet and

pressed into the groove until it

clicks. Mount in any 90 degree

angle.

6b. Using two M4 screws (not sup-

plied) the valve can be mounted

onto a plate or similar. The

screws may not extend more

than 5 mm on the backside of

the bracket.

7. Use counterforce when tighten-

ing the pipe connection, i.e. use

a wrench on both the valve

body and the pipe connection

(max. 25 Nm). It is recommended

to compress a rubber seal

against the end of the thread

connection. Alternatively it may

be assembled using a pipe joint

sealing compound.

NOTE: Do not use a tapered

thread.

7a. On variants with hose outlet:

Use only hoses which ﬁt tightly

on the hose connection (3/4”)

and use a steel clamp or similar

to safely tighten and secure the

hose.

8. Do not apply forces to the arma-

ture tube or use it as a lever

when mounting the valve.

9a. On variants with threaded

outlet: It is recommended to

mount the valve near bends as

thermal expansion of the pipes

may stress the valve.

9b. The pipes on both sides of the

valve must be securely fastened.

Mounting the coil:

You can only use AM or AP coils on

EV220T polymer valves. To connect

power to the coil, use Danfoss power

connector 042N0156, or a similar

DIN connector.

1a. Mount leads in the DIN plug to

match the pins as shown in the

picture.

Earth has to be mounted on the

ﬂat pin.

NOTE: The valve body can NOT

be used as a leader to ground

the coil through the piping

system.

1b. Mount the coil, washer and nut

as shown. The nut can be hand

tightened.

2. The cable has to be mounted as

shown in the picture. This pre-

vents water from seeping into

the cable ﬁtting.

Coil replacement:

1. Disconnect the coil from the

power supply before removing it

from the valve. Failure to discon-

nect the power will cause the coil

to overheat and thereby be

damaged.

2. Remove the nut and washer to

dismount the coil.

Trouble shooting

Failure: The valve does not open.

Possible cause:

– The diﬀerential pressure may be

too high.

– Dirt particles may be blocking

the armature (2) or the pilot

nozzle (3).

– The coil could be mounted -or

connected incorrectly.

Failure: The valve does not close.

Possible cause:

– The small equalizing hole (1) in

the diaphragm may be blocked

by particles.

– The valve may be mounted back-

wards. Check to be sure that the

arrow on the valve body is

pointing in the direction of the

ﬂow.

Leak: Dirt may be preventing the

diaphragm from sealing properly

against the oriﬁce.

Reduced ﬂow: The ﬁlter may be

blocked. Check and clean the ﬁlter.

Caution: Do not disassemble the

valve cover or armature tube.

If you have problems relating to the

function of internal components or

are unable to identify the problem,
