HYDRAULIC KIT
Components
Return circuit components (pump side)
Shutoff ball valve with integrated backflow preventer as well as filling and
draining valve.
The shutoff ball valve allows the return line to be split between the collector and
the heat accumulator .
The special ball cock design provides various functions . If the handle is pointing
in the direction of flow the system medium can circulate . An integrated backflow
preventer stops the medium flowing in the opposite direction and also acts as a
gravity brake . Turning the handle 90º to the right closes the ball cock in the direc-
tion of the medium flow and allows the upper system part (collector) to be filled
and emptied using the fill and drain valve . Turning the handle 90º to the left closes
the ball cock in the direction of the medium flow and allows the lower system part
(reservoir) to be filled using the fill and drain valve . A male thread G 3/4” is provided
on the fill and drain valve for connecting a hose . Holes are provided in the handle of the ball valve
so that it can be sealed to protect against unintentional closing .
Circulating pump solar version
This circulation pump, included as standard in the scope of delivery and integrated in the hydraulic
kit, covers a large delivery range . The required operating point can be preselected using one of
the three levels .
A pump can be replaced without having to empty the system using the stop cocks on the suction
side (TacoSetter Inline UN) and the pressure side (Shutoff ball valve) .
TacoSetter Inline 130 balancing valve
Precision adjustment at the balancing valve allows the required delivery quantity to be adapted
to system requirements . The proven combination of balancing valve and flow indicator in one
housing in the hydraulic kit balancing valves means that no additional measuring components
are required for the TacoSetter Inline UN . Flow rate indication is constant, i .e . the adjustment can
be immediately verified by means via the flow rate indicator . The indicator is pre-calibrated for a
medium viscosity of 2 .3 mm2/s . This does away with the need for correction curves . The con-
nection flange on the outlet side is directly screwed onto the 1 ½" pump connector fittings which
means there are no seal locations for further adapter components .
Connector ADG
The connector fitting with G 3/4” connecting thread for the expansion vessel is connected in series
with the circulation pump . This arrangement prevents negative working pressure conditions in
even critical systems and avoids reductions in the working pressure, one of the main causes of
early evaporation of the medium .
Thermometer
The thermometer with a range from 0 to 160ºC constantly indicates the medium temperature of
the flow circuit . The temperature is recorded directly in the medium to minimize the reaction time .
The sensor is inserted in a protective pipe so that it can be exchanged without having to empty
the system .
Flow circuit components (venting
side)
Shutoff ball valve with safety valve
and integrated backflow preventer
The shutoff ball valve allows the flow
circuit line to be divided between the
collector and the heat accumulator .
As required by safety regulations, the
connection between the collector and
safety valve is not interrupted in any
of the ball valve positions . The safety
valve thus protects the system compo-
nents against excessive over-pressure
in all operating phases .
Holes are provided in the handle of the ball valve so
that it can be sealed to protect against unintentional
closing . This prevents unintentional disconnection
of the connecting line between the collector and the
expansion vessel at this point .
Ventilating flask with ventilating valve
The purpose of the venting tank is to remove air from
the medium flowing through the tank . The venting
tank can hold up to approx . 2 .5 dl of air and has a
bleeder valve for releasing the air . The ventilating
valve is routed to the outside through the insulation
which means that it can be accessed even when the
insulating casing is on . The outlet has a suitable fitting
for easy attachment of a hose .
The frequency and quantity of the collected air can be
used to check the Leak tightness of the system
Manometer
The pressure gauge with a range from 0 to 10 bar
indicates the system pressure .
Thermometer
The thermometer with a range from 0 to 160ºC
constantly indicates the medium temperature in the
flow circuit . The temperature is recorded directly in
the medium to minimize the reaction time . The sen-
sor is inserted in a protective pipe so that it can be
exchanged without having to empty the system .
