ESBE VTC 317 charging valve 55°C or 60°C with pump screw connection 1 ½" x 1" IT

The ESBE VTC317 series is a thermal
3-way valve that protects the boiler from too low
return temperatures is designed. The maintenance
a high and stable return temperature increases the
Efficiency of the boiler, reduces tar formation and
extends the life of the boiler. The VTC317 valve
is used in heating applications with up to 30 kW where
Solid fuel boilers feed the storage. The valve
is installed in the return line to the 60°C boiler.

▸ Function
The valve regulates with two connections, making it
is easy to install and there are no control valves in the system
Bypass line is required.
The function of the valve does not depend on the
Installation position.
The valve contains a thermostat that works at a
outgoing mixed water temperature of 60°C
in port AB starts to open port A.
Port B is completely closed when the temperature in
Connection A exceeds the target opening temperature by 10°C.

▸ Media
The additives include a maximum of 50% glycol for antifreeze
and oxygen-binding compounds permitted. That I
the addition of glycol to the system water on both the
Viscosity as well as heat conduction affects this
to be taken into account when dimensioning the valve.
Adding 30-50% glycol reduces this
maximum performance of the valve by 30-40%. A lesser one
Glycol concentration is negligible.
