Valve

Hydraulic pressure should be avoided in both heating installations and hydraulic networks. In a boiler, you find the 3-bar valve which is actually the heating safety valve, as well as the 7-bar safety valve which is for the hydraulic part. Other heating spare parts are useful, such as the expansion tank or the hydraulic pressure reducer.
When in a boiler room, a heating valve and a sanitary valve are also used, sized according to the installation. Such a spare part for the boiler room must have a bronze body to last over time.
It should be according to a certain nominal diameter to fit the piping, just like the nominal pressure.
