(Main)Industrial valves - Actuators - Part 4: Hydraulic part-turn actuators for industrial valves - Basic requirements
Industrial valves - Actuators - Part 4: Hydraulic part-turn actuators for industrial valves - Basic requirements
This document specifies basic requirements for hydraulic 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 hydraulic actuators which are integral parts of control valves and to hydraulic actuators designed for permanent immersion in fresh or sea water as well as electro-hydraulic actuators.
Other requirements, or conditions of use, different from those indicated in this document can vary upon request.
Industriearmaturen - Antriebe - Teil 4: Hydraulische Schwenkantriebe für Industriearmaturen - Grundanforderungen
Dieses Dokument gibt die Grundanforderungen an sowohl doppelt als auch einfach wirkende hydraulische Schwenkantriebe für Armaturen für An-Aus- und Modulations-Regelfunktionen an.
Es enthält Leitlinien, Empfehlungen sowie Verfahren für Gehäuse- und Korrosionsschutz, Kontrollen und Prüfungen.
Es gilt nicht für hydraulische Stellantriebe, die fester Bestandteil von Regelventilen sind, für hydraulische Stellantriebe, die für ständiges Eintauchen in Süß- oder Meerwasser ausgelegt sind, oder für elektrisch-hydraulische Stellantriebe.
Weitere Anforderungen oder Anwendungsbedingungen, die von den in diesem Dokument genannten abweichen, können auf Anfrage festgelegt werden.
Robinetterie industrielle - Actionneurs - Partie 4: Actionneurs hydrauliques à fraction de tour pour robinetterie industrielle - Prescriptions de base
Le présent document spécifie les exigences de base pour les actionneurs hydrauliques 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 à modulation.
Il comprend des lignes directrices, des recommandations et des méthodes pour l'enveloppe et la protection contre la corrosion, le contrôle et les essais.
Il ne s'applique pas aux actionneurs hydrauliques qui font partie intégrante de robinets de régulation, ni aux actionneurs hydrauliques, conçus pour une immersion permanente dans l'eau douce ou l'eau de mer, ni aux actionneurs hydroélectriques.
D'autres exigences ou conditions d'utilisation, différentes de celles indiquées dans le présent document, peuvent varier sur demande.
