Safety Warning; English - Danfoss EV245B Manual De Instrucciones

identification of the valve
Valve type, code number, production
date (wwy; eg. 371 / 'week 37, year
2011') and country of origin is
printed on the valve armature tube.
Mounting the valve
1. Clean the pipe system before
mounting the valve.
2. Danfoss recommends to mount
a filter in front of the valve. This
will prevent impurities from
getting inside the valve and there
by avoid damage of the valve
function.
3. The arrow on the valve body
must point in the direction of the
flow. The arrow can be found on
the side of the valve body.
4. Mount the valve as shown in
the picture. The valve can be
mounted with a max. angle of
45° from upright position.
5. Use counterforce when tightening
the pipe connection, i.e. use a
wrench on both the valve body
and the pipe connection.
6. The pipes on both sides of the
valve must be securely fastened.

saFety Warning

7. Test the system. Maximum test
pressure 25 bar.
8. The steam temperature can be
up to 185°C. At this temperature
steam is invisible and therefore
highly dangerous.
The valve must be protected
from external forces and impacts.
Mounting the coil
You can only use dedicated steam
coils (BB, BN up to 160°C and BQ, BR
up to 185ºC. BB DC only up to 140°C
and BR DC only up to 160ºC) on
EV245B steam valves.

To connect power to the coil, use
Danfoss power connector 042N0156,
or a similar DIN connector.
1a. Mount leads as shown in the pic-
ture. Earth has to be mounted on
the flat pin.
2a. Mount the O-ring.
3a. Click the coil on the valve.
1b. Mount leads as shown in the pic-
ture. Earth has to be mounted on
the terminal to the left.
2b. Mount the coil as shown in the
picture. Mount without the
O-ring.
4. The cable has to be mounted
as shown in the picture. This
prevents 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
disconnect the power will cause
the coil to overheat and thereby
be damaged.
2. Use a screwdriver as a lever to
remove the coil from the valve.
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 piston.
– The coil could be mounted or
connected incorrectly.
Failure: The valve does not close.
possible cause:
– The small equalizing holes (1) in
the piston may be blocked by
particles.
