EN 13611:2019, Clause 1 applies with the following modification and addition: Modification: The 1st paragraph of EN 13611:2019, Clause 1 is replaced by: This document specifies the safety, design, construction, and performance requirements and testing for automatic shut-off valves for burners and appliances burning one or more gaseous fuels, hereafter referred to as \u201cvalves\u201d. This document is applicable to valves with declared maximum inlet pressures up to and including 500 kPa and of nominal connection sizes up to and including DN 250. Addition: This document is applicable to: – electrically actuated valves; – valves actuated by fluids where the control valves for these fluids are actuated electrically, but not to any external electrical devices for switching the control signal or actuating energy; – valves where the flow rate is controlled by external electrical signals, either in discrete steps or proportional to the applied signal; – valves fitted with closed position indicator switches. An assessment method for valve designs is given by this document. The 4th paragraph of EN 13611:2019, Clause 1 is removed.<\/p>\n
