RFF15~150
PRESSURE SUSTAINING VALVE
Description
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 back pressure, when pressure returns the valve will begin to open again.
Typically used to maintain pressure for critical systems upstream, by limiting flow to non-critical systems down stream if required to do so.
