2180 Air Relief Valve Repair Kits

In practice the valve should be matched to the system to be protected

such that the maximum airflow rate of the valve is never utilized, i.e.

the valve should be capable of relieving a sufficient volume flow rate

of air at the opening pressure to ensure that the system pressure

drops significantly. If the valve is open and the system pressure

continues to rise above the opening pressure then the valve is

relieving less air than is being put into the system. This is a potentially

dangerous situation that may lead to over pressurization. Air relief

valves should always be matched to the system to be protected such

that the relieving airflow rate of the valve at the maximum allowable

system pressure, and ideally at the opening pressure, is well in

excess of the system input flow rate at that same pressure.
