Railway applications - Braking - Distributor valves and distributor-isolating devices

This European Standard applies to distributor valves and distributor-isolating devices.
The distributor valves contained in this European Standard are of graduated release type. Direct release types are not included.
Functionally they are regarded as not containing relay valves of any type, even if the relay valves are physically an integral part of the distributor valves.
This European Standard applies to both distributor-isolating devices mounted separate from the distributor valve and distributor-isolating devices integral with the distributor valve.
This European Standard specifies the requirements for the design, testing and quality assurance of distributor valves and distributor-isolating devices.
For interoperable freight wagons, these devices which are operated by compressed air according to EN 14198 are assessed according to the respective technical specification of interoperability.

Bahnanwendungen - Bremse - Steuerventile und Bremsabsperrhähne

Dieses Dokument gilt für Steuerventile, die nach den TSI Spezifikationen als Interoperabilitätskomponenten für Druckluftbremsen von interoperablen Schienenfahrzeugen, die durch Druckluft betätigt werden, bewertet werden.
Die Steuerventile, wie sie in diesem Dokument enthalten sind, sind von mehrlösiger Bauart. Einlösige Ventile werden nicht behandelt.
Die Betrachtung der Funktionen erfolgt so als ob kein Relaisventil enthalten wäre, auch wenn die Relaisventile physikalisch in das Steuerventil integriert sein können.
Dieses Dokument definiert die Anforderungen an Konstruktion, Abmessungen, Prüfung und Qualitätssicherung des Steuerventiles. Diese Anforderungen können nicht ausreichend genau beschrieben werden, um die fachgerechte Herstellung oder zweckmäßige Konstruktion sicherzustellen. Daher ist jeder Hersteller dafür verantwortlich, alle notwendigen Schritte zu unternehmen, die die Qualität von Konstruktion, Bearbeitung und Herstellung im Einklang mit fachgerechter Ingenieurspraxis sowie ausreichender Fertigungsqualität sicherstellen.

Applications ferroviaires - Freinage - Distributeur de freinage et robinet d'isolment

Le présent document s’applique aux distributeurs de freinage et aux robinets d’isolement.
Les distributeurs de freinage décrits dans la présente norme européenne sont de type à desserrage gradué. Les types à desserrage direct ne sont pas couverts.
Sur un plan fonctionnel, ils sont considérés comme ne comportant pas de relais pneumatique d’aucune sorte, même si les relais pneumatiques font partie intégrante des distributeurs de freinage.
La présente norme européenne s’applique aux robinets d’isolements montés séparément du distributeur de freinage ainsi qu’aux robinets d’isolement intégrés au distributeur de freinage.
Elle spécifie les exigences à respecter pour la conception, les essais et l’assurance qualité des distributeurs de freinage et des robinets d’isolement.
Pour les wagons de marchandises interopérables, ces dispositifs fonctionnant à l’air comprimé conformément à l’EN 14198, sont évalués selon les Spécifications Techniques d’Interopérabilité concernées.

This is considered to be sufficient for the purpose of this clause 3.3.2 distributor valve apparatus to control a pneumatic output pressure as an inverse function of the variation of an input pressure as the main function NOTE 1 See Figure 1 and Figure 2. NOTE 2 For the purpose of this European Standard, input pressure is considered to be the brake pipe pressure and output pressure is considered to be the brake cylinder pressure or the pilot pressure, which controls the brake cylinder pressure via a relay valve.
