High Capacity Gas Flow Limitor (ECV) to GNI AM/SP/033. Inlet Pressure: 500 mbar to 4.0 bar. Capacity: 50 S.C.M.H. to 135 S.C.M.H. Temperature: -20°C to + 40°C.
The Donkin Flow Limitor is for direct insertion into the service pipe. It 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.
