Flow Rate Control Valves

FR - Flow Rate Control Valve
The valve limits the flow rate in the network to a preset value, regardless of pressure variations. The valve opens fully when the flow rate drops below the set-point.
FE - Excessive Flow Shut-Off Valve
The valve closes when the flow rate exceeds the normal value (due to pipe rupture, for example). Reopening is by manual reset only.
