COMBINED DUNGS VALVE (monobloc) mod.MB-DLE...B01
The gas valve unit DUNGS MB - DLE...
is made up of:
1) A safety valve which closes opens
rapidly.
2) A principle valve which opens in
two stage (5). The first opening
stage occurs rapidly (release) and
is adjustable by unscrewing the
knob (2) and inserting the back part
of the regulating pin underneath.
The + and symbol can be seen on
the head of the valve and these
indicate the direction in which the
pin should be turned in order to
increase or the ignition output (the
fi rst stage of the valve opening). By
rotating in a clockwise direction, the
initial delivery (ignition fl ame) can
be reduced; in an anti-clockwise
direction, the initial delivery is in-
creased. The complete run from
zero to maximum, and viceversa, is
slightly more than three turns (40%
of the total opening). When the fi rst
opening stage has taken place, the
valve comtinues to open slowly
and takes 15 seconds to reach the
maximumopen position. To regulate
maximum delivery desired, loosen
the locking screw (4) (the one with
the protruding head and not the one
locked and sealed with paint) and
turn knob (3). Rotate in a clockwise
direction to reduce delivery and in
anti-clockwise direction to increase
it. It should be pointed out that
when the regulating knob is turned,
the end - of - the - run which limits
the operating of the valve moves;
therefore, when the knob has been
turned untilit reaches the - sign, the
valve will not open and the burner
will not ignite. To get ignition, it's
necessary to turn the knob in an
anti-clockwise direction towards the
+ sign. The complete run from zero
to maximum and viceversa is neary
six turns of the knob. This regulating
operation (for maximum and ignition
output) must be carried out without
forcing against the end - of - the
- run - positions.

3) The pressure stabilizer (10) can
be regulated (see table) by ma-
noeuvring the screw which can be
reached by sliding the cover (1) to
one side. The complete run from
the maximum to the position and
viceversais about 80 turns. Do not
force against the end - of - the - run
positions. Around the screw are
arrows with symbols which indicate
the sense of rotation: to increase
pressure, rotate in a clockwise
direction, to reduce it, rotate in
an anti-clockwise direction. This
stabilizer hermetically closes "up-
stream" and "downstream" when
there is no fl ow of gas. Dfferent
springs to obtain different pressure
value from those described above
are not foreseen. To regulate the
pressure stabilizer, connect a
water manometer to the rubber
tube holder installed on the tap
(8) in correspondence with the
exit of the stabilizer.
4) The small entry fi lter (12) can be
reached for cleaning by removing
one of the two side closing plates.
5) The minimum pressure switch (14).
To regulate it remove the transpa-
rent cover and operate the black
knob. The reference mark is the
small rectangle to be found on the
yellow disk which the regulating
knob rotates around.
6) At entry, a tap (13) has been fi tted
to the connction fl ange to measure
the entry pressure. At the exit of the
connection fl ange, there is also a
tap (7) to measure the pressure in
exit.
7) The side pressure taps (9), indica-
ted as Pe, are in communication
with the entry pressure.
8) The side pressure taps (8) indicated
as Pa, are used to measure the
pressure coming out of the stabili-
zer. It might be useful to know, that
the pressure coming out of the valve
unit (to be measured at tap 7), cor-
risponds to the pressure regulated
