Service Check Valves

R39.83R61.44 Incl VAT

A service check valve relies on a pressure differential to work. They require a higher pressure on the input side of the valve than the output side to open the valve. When the pressure is higher on the outlet side (or the input side pressure is not high enough), the valve will close. This makes it ideal for service/maintenance purposes as no water is lost in the system, when for example you remove a part for cleaning, like the air relief valve.
