The purpose of a 3-way control valve is to shut off water flow in one pipe while opening water flow in another pipe, to mix water from two different pipes into one pipe, or to separate water from one pipe into two different pipes.
A heating system in a building can be based on radiators, convectors, floor heating, air heating or a combination of these. Using air heating is a fast but expensive way to heat up a building.
To prevent corrosion and problems with operation, heating and air-conditioning systems must be constructed so that air can be removed both when the system is filled and during subsequent operation.
Balancing of heating and cooling systems is performed to ensure that the correct amount of water is present at all consumption points. Balancing is carried out by building balancing valves into the system, thereby adding adjustable resistance.
Consumers who live in areas with no district heating have to use their own boiler to produce central heating. A boiler installation has the following components: burner, nozzles, boiler casing, hot-water tank (integrated or separate) and a chimney.
The primary task of the boiler shunt is to ensure that the difference in temperature between the top and the bottom of the boiler is not too high. A high temperature difference can cause tensions in the material and thus reduce the life of the boiler.
