Pressure sustaining valves are designed to maintain a pre-set back pressure, if the back pressure drops to the set value the valve will begin to close to maintain pressure, when pressure returns the valve will begin to open again.
Pressure gauge indicates the sustained back pressure (Upstream pressure).
