DIN EN 16678
Safety and control devices for gas burners and gas burning appliances - Automatic shut-off valves for operating pressure of above 500 kPa up to and including 6 300 kPa; German version EN 16678:2015
Sicherheits- und Regeleinrichtungen für Gasbrenner und Gasbrennstoffgeräte - Automatische Absperrventile für einen Betriebsdruck über 500 kPa bis einschließlich 6 300 kPa; Deutsche Fassung EN 16678:2015
This European Standard specifies the safety, design, construction and performance requirements and testing for automatic shut-off valves with or without modulating control functions (hereafter referred to as "valves") for burners and appliances burning one or more gaseous fuels according to EN 437:2003+A1:2009. This European Standard is applicable to valves with declared maximum inlet pressures of more than 500 kPa (5 bar) and up to and including 6 300 kPa (63 bar). This European Standard is applicable to: - electrically operated valves and to valves actuated by fluids including the pilot valves for these fluids if actuated electrically and including release valves, but not to any external electrical devices for switching the actuating energy; - automatic shut-off valves where the flow rate is controlled by external electrical signals proportional to the applied signal. This European Standard is not applicable to valves specifically designed for use in transmission and distribution networks.
