Valve

In a boiler room or a collective hydraulic network, the quality of the circulating water is crucial for the longevity of the equipment. Ball valves, expansion vessels, safety valves, and anti-pollution check valves constitute the first lines of protection against pressure variations and the risks of contamination of the drinking water network.

On Expertbynet.fr, find a selection of hydraulic safety parts for boiler rooms, compliant with current standards, to effectively protect your installation and the health of occupants.

The boiler room is effectively the boiler of a building, just like the condensing boiler installed in a house to heat the living space. In the boiler room, different heating products exist with varying uses.
The ball valve allows you to open or close the hydraulic network, whether gas or heating. The safety valve and expansion tank act as safety elements protecting the network.
The anti-pollution check valve is made of a brass body and is limited to a certain operating pressure. Thanks to this valve for the boiler room, you avoid pressure variations in the hydraulic distribution network, meaning in drinking water, which sometimes also brings non-potable water. This avoids water backflow that could threaten your health.
