Resumen:
This European Standard specifies the safety, design, construction and performance requirements and testing for automatic shut-offvalves with or without modulating control functions (hereafter referred to as 'valves') for burners and appliances burning one or moregaseous 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 6300 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 andincluding 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.NOTE Provisions for final product inspection and testing by the manufacturer are not specified.
