(Main)Industrial valves - Actuators - Part 3: Pneumatic part-turn actuators for industrial valves - Basic requirements
Industrial valves - Actuators - Part 3: Pneumatic part-turn actuators for industrial valves - Basic requirements
This document specifies basic requirements for pneumatic part-turn valve actuators, both double acting and single acting, used for on-off and modulating control duties.
It includes guidelines, recommendations and methods for enclosure and corrosion protection, control and testing.
It does not apply to pneumatic actuators which are integral parts of control valves and to pneumatic actuators designed for permanent immersion in fresh or sea water.
Other requirements, or conditions of use, different from those indicated in this document, are expected to be subject to negotiations, between the purchaser and the manufacturer/supplier, prior to order.
Industriearmaturen - Antriebe - Teil 3: Pneumatische Schwenkantriebe für Industriearmaturen - Grundanforderungen
Dieses Dokument legt Grundanforderungen sowohl an in beide Richtungen als auch an in eine Richtung wirkende pneumatische Schwenkantriebe für Armaturen für Auf-Zu- und Modulations-Regelfunktionen fest.
Es enthält Leitlinien, Empfehlungen sowie Verfahren für Gehäuse- und Korrosionsschutz, Kontrollen und Prüfungen.
Es ist nicht anwendbar für pneumatische Stellantriebe, die integraler Bestandteil von Regelventilen sind, oder für pneumatische Stellantriebe, die für ständiges Eintauchen in Süß- oder Meerwasser ausgelegt sind.
Es wird erwartet, dass andere Anforderungen oder Anwendungsbedingungen als die, die in diesem Dokument angegebenen sind, vor Auftragserteilung zwischen dem Käufer und dem Hersteller/Lieferanten verhandelt werden.
Robinetterie industrielle - Actionneurs - Partie 3 : Actionneurs pneumatiques à fraction de tour pour robinetterie industrielle - Prescriptions de base
Le présent document spécifie les prescriptions de base pour les actionneurs pneumatiques à fraction de tour d’appareil de robinetterie à double et à simple effet, utilisés pour les fonctions tout ou rien et les fonctions de régulation.
Il comprend des lignes directrices, des recommandations et des méthodes pour la protection de l’enceinte et contre la corrosion, le contrôle et les essais.
Il ne s’applique pas aux actionneurs pneumatiques qui font partie intégrante de robinets de régulation, ni aux actionneurs pneumatiques, conçus pour une immersion permanente dans l’eau douce ou l’eau de mer.
Des prescriptions ou conditions relatives à l’utilisation, autres que celles mentionnées dans le présent document, sont prévues pour être négociées entre l’acheteur et le fabricant/fournisseur, avant la commande.
Industrijski ventili - Pogoni - 3. del: Pnevmatični pogoni z delnim zasukom za industrijske ventile - Osnovne zahteve
Ta dokument podaja osnovne zahteve za pnevmatične pogone z delnim zasukom za industrijske ventile z dvosmernim in enosmernim delovanjem, ki se uporabljajo za vklopno-izklopne in modulacijsko krmilne naloge. Vključuje smernice, priporočila in metode za zaščito, nadzor ter preskušanje ohišij in proti koroziji.
Ne uporablja se za pnevmatične pogone, ki so sestavni deli regulacijskih ventilov.
O drugih zahtevah ali pogojih uporabe, ki niso navedeni v tem dokumentu, se morata kupec in proizvajalec/dobavitelj dogovoriti pred naročilom.
Izrazi in definicije v zvezi s tem evropskim standardom so navedene v predlogu standarda FprEN 15714-1.
