EN ISO 4126-4:2013

Safety devices for protection against excessive pressure - Part 4: Pilot-operated safety valves (ISO 4126-4:2013)

ISO 4126-4:2013 specifies general requirements for pilot operated safety valves, irrespective of the fluid for which they are designed. In all cases, the operation is carried out by the fluid in the system to be protected.
It is applicable to pilot operated safety valves having a valve flow diameter of 4 mm and above which are for use at set pressures of 0,1 bar gauge and above. No limitation is placed on temperature.
ISO 4126-4:2013 is a product standard and it is not applicable to applications of pilot operated safety valves.

Sicherheitseinrichtungen gegen unzulässigen Überdruck - Teil 4: Pilotgesteuerte Sicherheitsventile (ISO 4126-4:2013)

Dieser Teil von ISO 4126 legt allgemeine Anforderungen an pilotgesteuerte Sicherheitsventile unabhängig von dem Medium fest, für das sie ausgelegt sind. Die Funktion wird in allen Fällen durch das Medium in dem zu schützenden System ausgelöst.
Die Norm gilt für pilotgesteuerte Sicherheitsventile mit einem engsten Strömungsdurchmesser von mindestens 4 mm und für Ansprechdrücke von mindestens 0,1 bar. Temperaturgrenzen sind nicht festgelegt.
Diese Norm ist eine Produktnorm und behandelt keine Anwendungsfälle für pilotgesteuerte Sicherheitsventile.

Dispositifs de sécurité pour protection contre les pressions excessives - Partie 4: Soupapes de sûreté pilotées (ISO 4126-4:2013)

L'ISO 4126-4:2013 spécifie les exigences générales des soupapes de sûreté pilotées, quel que soit le fluide pour lequel elles sont conçues. Dans tous les cas, le fonctionnement est assuré par le fluide contenu dans le système à protéger.
Elle est applicable aux soupapes de sûreté pilotées présentant un orifice d'écoulement de diamètre supérieur ou égal à 4 mm, qui sont utilisables à des pressions de début d'ouverture de 0,1 bar effectif et au-dessus. Aucune limitation en température n'est fixée.
L'ISO 4126-4:2013 est une norme de produit et elle n'est pas applicable à la mise en ?uvre des soupapes de sûreté pilotées.

Naprave za varovanje pred visokim tlakom - 4. del: Predkrmiljeni varnostni ventili (ISO 4126-4:2013)

Ta del standarda ISO 4126 določa splošne zahteve za pilotsko upravljane varnostne ventile ne glede na tekočino, za katero so oblikovani. V vseh primerih delovanje poteka s tekočino v sistemu, ki naj se zaščiti. Uporablja se za pilotsko upravljane varnostne ventile s premerom pretoka 4 mm in več, ki se uporabljajo pri nastavljenih tlakih 0,1 bara in več. Temperatura ni omejena. To je standard izdelka in ne velja za uporabo pilotsko upravljanih varnostnih ventilov.
