DIN EN 16678:2013-10

This European Standard specifies the safety, construction and performance requirements for automatic shut-off and control valves for use with gas burners, gas appliances and similar use, hereafter referred to as 'valves'. This European Standard is applicable to valves with declared maximum inlet pressures of more than 500 kPa (5 bar) and up to and including 6300 kPa (63 bar) for use with one or more fuel gases in accordance with EN 437 in vaporous phases. This European Standard is applicable to: - electrically operated valves and to valves actuated by fluids where the pilot valves for these fluids are actuated electrically, but not to any external electrical devices for switching the actuating energy, - valves where the flow rate is controlled by external electrical signals, either in discrete steps or proportional to the applied signal. This European Standard is not applicable to valves specifically designed for use in transmission and distribution networks. NOTE Provisions for final product inspection and testing by the manufacturer are not specified.
