Industrial valves. Actuators - Hydraulic part-turn actuators for industrial valves. Basic requirements Ingestion-build-61878 alteration and dismantling of hoists1 Scope This document provides 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 that are integral parts of control valves or to electro hydraulic actuators. Other requirements or conditions of use
