1. Drain valve
Danfoss - BVTS,
¾“
2. Submersible case with temperature-sensitive element
3. Safety cooling heat exchanger
4. Drain to sump
5. Boiler
6. Inlet of cold water
Valve Danfoss – BVTS
is
on the outlet of the cooling circuit of which sensor is placed at the side
part of a boiler and protects the boiler against overheating. When boiler water temperature
increases above 95°C, cooling circuit is filled up with tap water that takes the extra heat away. In
case of boiler overheating and opening of Danfoss – BVTS valve there must be secured the
permanent drain of heated water from the boiler cooling circuit into spillway.
Valve at the cold water inlet into the boiler cooling circuit must be permanently open and the
boiler cooling circuit must be connected to the functioning distribution of cold water (e.g. cold tap
water network) of temperature 10-15°C and operating overpressure 2-6 bar.
In case of thermostatic valve
Danfoss – BVTS
opening
the circulation of cooling water through
the cooling circuit is not guaranteed
it is a risk of boiler damage ! In such case the boiler
warranty is invalid.
Valve DANFOSS is not a part of a boiler!!!
