Automatic shut-off valves for gas burners and gas appliances; German version EN 161:2022
Automatische Absperrventile für Gasbrenner und Gasgeräte; Deutsche Fassung EN 161:2022
Overview
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 “valves”. 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. 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. This document (EN 161:2022) has been prepared by Technical Committee CEN/TC 58 "Safety and control devices for burners and appliances burning gaseous and/or liquid fuels", the secretariat of which is held by BSI (United Kingdom). The responsible German standardization committee is Joint Working Committee NA 041-03-10 GA "Gemeinschaftsarbeitsausschuss NHRS/NAA/NAGas: Sicherheits- und Regeleinrichtungen für wärmeerzeugende Geräte und Anlagen sowie für die Gasversorgung (SpA CEN/TC 58, WG 11, WG 13, WG 15 und ISO/TC 161, WG 3, WG 4, WG 5)" ("Joint working committee NHRS/NAA/NAGas: Safety and control devices for heating appliances and heat generating systems and for the gas distribution (SpA CEN/TC 58, WG 11, WG 13, WG 15 and ISO/TC 161, WG 3, WG 4, WG 5)") at DIN Standards Committee Heating and Ventilation Technology and their Safety (NHRS).
