Industrial valves - Actuators - Part 6: Hydraulic linear actuators for industrial valves - Basic requirements

This document specifies basic requirements for piston type hydraulic linear actuators for industrial valve, both double acting and single acting, used for on-off and modulating control duties. It includes criteria, method and guidelines for design, qualification, corrosion protection, control and testing.
It does not apply to hydraulic actuators which are integral parts of control valves. 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 - Stellantriebe - Teil 6: Hydraulische Linearantriebe - Grundlegende Anforderungen

Dieses Dokument legt Grundanforderungen an hydraulische, von Kolben angetriebene Linearantriebe für Industriearmaturen, die sowohl einfach als auch in beide Richtungen wirken und für Auf-Zu-Einschaltdauer und modulierende Steuerungsfunktionen verwendet werden, fest. Es enthält Kriterien, Verfahren und Leitlinien für Konstruktion, Qualifizierung, Korrosionsschutz, Kontrolle und Prüfung.
Es gilt nicht für hydraulische Stellantriebe, die feste Bestandteile von Regelventilen sind. Andere Anforderungen oder Anwendungsbedingungen als die, die in diesem Dokument angegeben sind, werden erwartungsgemäß vor Auftragserteilung zwischen dem Käufer und dem Hersteller/Lieferanten verhandelt.

Robinetterie industrielle - Actionneurs - Partie 6 : Actionneurs linéaires hydrauliques - Prescriptions de base

Le présent document spécifie les prescriptions de base pour les actionneurs linéaires hydrauliques à piston d’appareils de robinetterie, à double et à simple effet, utilisés pour des fonctions tout ou rien et des fonctions de régulation. Il comprend des critères, une méthode et des lignes directrices pour la conception, la qualification, la protection contre la corrosion, le contrôle et les essais.
Il ne s’applique pas aux actionneurs hydrauliques qui font partie intégrante des robinets de régulation. 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.
