Automatic shut-off valves for gas burners and gas appliances
This European Standard specifies the safety, construction and performance requirements for automatic shut-off 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 up to and including 500 kPa (5 bar) of nominal connection sizes up to and including DN 250 for use with one or more fuel gases in accordance with EN 437.
This European Standard is applicable to electrically operated valves and to 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.
An assessment method for valve designs is given by this European Standard.
This European Standard is also applicable to 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 also applicable to valves fitted with closed position indicator switches.
NOTE Provisions for final product inspection and testing by the manufacturer are not specified.
Automatische Absperrventile für Gasbrenner und Gasgeräte
Diese Europäische Norm legt die Sicherheits-, Bau- und Funktionsanforderungen an automatische Absperrventile
zur Verwendung mit Gasbrennern, Gasgeräten und ähnlichen Anwendungen, nachstehend Ventile
genannt, fest.
Diese Europäische Norm gilt für Ventile mit angegebenen höchsten Eingangsdrücken bis einschließlich
500 kPa (5 bar) und Nennweiten bis einschließlich DN 250, die zur Verwendung mit einem oder mehreren
Brenngasen nach EN 437 ausgelegt sind.
Diese Europäische Norm gilt für elektrisch betriebene Ventile und für Ventile, die durch Steuermedien angesteuert
werden, wenn die Steuerventile für diese Medien elektrisch geschaltet werden; sie gilt nicht für externe
elektrische Schalter, die das Steuersignal oder die Stellantriebsenergie beeinflussen.
Diese Europäische Norm gibt ein Bewertungsverfahren für die Auslegung und Konstruktion von Ventilen an.
Diese Europäische Norm gilt auch für Ventile, bei denen die Durchflussmenge durch externe elektrische
Signale entweder in Stufen oder proportional zum angelegten Signal gesteuert wird.
Diese Europäische Norm gilt auch für Ventile mit Schaltern, die die geschlossene Stellung anzeigen.
ANMERKUNG Bestimmungen für die Prüfung von Endprodukten durch den Hersteller sind nicht festgelegt.
Robinets automatiques de sectionnement pour brûleurs à gaz et appareils à gaz
La présente Norme européenne spécifie les exigences de sécurité, de construction et de fonctionnement des
robinets automatiques de sectionnement pour brûleurs à gaz, appareils à gaz et similaires, dénommés ciaprès
« robinets ».
La présente Norme européenne s'applique aux robinets dont la pression amont maximale déclarée est
inférieure ou égale à 500 kPa (5 bar), de diamètres nominaux de raccordement inférieurs ou égaux à DN 250
utilisés avec un ou plusieurs combustibles gazeux conformément à l'EN 437.
La présente Norme européenne s'applique aux robinets de sectionnement commandés électriquement et aux
robinets de sectionnement actionnés par des fluides si les vannes de commande de ces fluides sont
commandées électriquement, mais en aucun cas aux dispositifs électriques externes commutant le signal de
commande ou libérant l'énergie motrice de commande.
Une méthode d'évaluation de la conception des robinets est donnée par la présente Norme européenne.
La présente Norme européenne s'applique également aux robinets dans lesquels le débit est commandé par
des signaux électriques externes, soit par pas, soit proportionnellement au signal reçu.
La présente Norme européenne s'applique également aux robinets équipés de contacts indicateurs de
position de fermeture.
NOTE Les dispositions relatives aux contrôles et aux essais du produit final par le fabricant ne sont pas spécifiées.
Samodejni zaporni ventili za plinske gorilnike in plinske aparate
Ta evropski standard določa zahteve za varnost, konstrukcijo in delovanje samodejnih zapornih ventilov za uporabo s plinskimi gorilniki in plinskimi aparati ter za podobno uporabo, v nadaljevanju »ventili«.
Ta evropski standard velja za ventile z maksimalnimi nazivnimi vstopnimi tlaki do vključno 500 kPa (5 bar) in nazivnimi velikostmi priključkov do vključno DN 250, ki se uporabljajo z enim ali več kurilnimi plini v skladu z EN 437.
Ta evropski standard velja za električne ventile in ventile, ki se aktivirajo s tekočinami, pri katerih se krmilni ventili za te tekočine aktivirajo električno, a ne za zunanje električne naprave za preklapljanje krmilnega signala ali aktivacijske energije.
Ta evropski standard navaja metodo ocenjevanja zasnove ventilov.
Ta evropski standard velja tudi za ventile, pri katerih je hitrost pretoka krmiljena z zunanjimi električnimi signali bodisi v posameznih korakih ali sorazmerno z uporabljenim signalom.
Ta evropski standard velja tudi za ventile, opremljene s pokazateljskim stikalom za zaprti položaj.
OPOMBA: Določbe za preverjanje in preskušanje končnega proizvoda, ki ju izvaja proizvajalec, niso navedene.
