Automatic shut-off valves for gas burners and gas appliances
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 “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.
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.
Automatische Absperrventile für Gasbrenner und Gasgeräte
EN 13611:2019, Abschnitt 1, gilt mit folgender Änderung und Ergänzung:
Änderung:
Der erste Absatz von EN 13611:2019, Abschnitt 1, wird ersetzt durch:
Dieses Dokument legt die Sicherheits , Auslegungs , Konstruktions- und Leistungsanforderungen sowie die Prüfung von automatischen Absperrventilen für Brenner und Brennstoffgeräte für einen oder mehrere gasförmige Brennstoffe, nachstehend als „Ventile“ bezeichnet, fest.
Dieses Dokument gilt für Ventile mit einem angegebenen höchsten Eingangsdruck bis einschließlich 500 kPa und mit Anschlussnennweiten bis einschließlich DN 250.
Ergänzung:
Dieses Dokument gilt für:
— Elektrisch betätigte Ventile;
— Ventile, die durch Steuermedien betätigt werden, wenn die Steuerventile für diese Medien elektrisch betätigt werden, aber nicht für externe elektrische Elemente, die das Steuersignal oder die Antriebsenergie schalten;
— Ventile mit Durchflussmengenregelung durch externe elektrische Signale entweder in Stufen oder proportional zum angelegten Signal;
— Ventile mit Meldeschaltern für die geschlossene Stellung.
Dieses Dokument gibt ein Bewertungsverfahren für die Auslegung und Konstruktion von Ventilen an.
Der vierte Absatz von EN 13611:2019, Abschnitt 1, entfällt.
Robinets automatiques de sectionnement pour brûleurs à gaz et appareils à gaz
L’article 1 de la norme EN 13611:2019 s’applique avec la modification et l’addition suivantes :
Modification :
Le 1er paragraphe de l’article 1 de la norme EN 13611:2019 est remplacé par ce qui suit :
Le présent document spécifie les exigences de sécurité, de construction et de fonctionnement et les essais applicables aux robinets automatiques de sectionnement pour brûleurs à gaz, appareils à gaz et similaires, dénommés ci-après « robinets ».
Ce document s'applique aux robinets dont la pression amont maximale déclarée est inférieure ou égale à 500 kPa, de diamètres nominaux de raccordement inférieurs ou égaux à DN 250.
Addition :
Le document est applicable aux :
- robinets de sectionnement commandés électriquement ;
- 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 ;
- robinets dans lesquels le débit est commandé par des signaux électriques externes, soit par pas, soit proportionnellement au signal reçu ;
- robinets équipés de contacts indicateurs de position de fermeture.
Une méthode d'évaluation de la conception des robinets est donnée par le présent document.
Le 4ième paragraphe de l’article 1 de la EN 13611 :2019 est supprimé.
