Micro RFMT RFMF Pressure sustaining valves are designed to maintain a precise pre-set back pressure, the large diaphragm can detect any minor changes and 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).
