Donkin Flow Limitor (Emergency Flow Valve)
Gas Flow Limitor (ECV) to GNI AM/SP/033. Temperature range: -20oC to +40oC. Inlet pressure 500mbar to 4.0 bar. Capacity 9 S.C.M.H. to 31 S.C.M.H.
The Donkin Flow Limitor is for direct insertion into the service pipe. The Donkin 25mm Flow Limitor is an emergency shut-off valve that provides service line safety, service line theft protection and automatic shut-off, remaining closed until repairs have been made. Once the fault has been rectified, a small bleed-by flow enables the service to regain pressure, equalising the pressure and allowing the unit to reset for normal operation.
