This document provides basic requirements for electric valve actuators, used for on-off and control valves. It includes guidelines for classification, design, enclosure and corrosion protection, and methods for conformity assessment. Combinations of electric multi-turn actuators and gearboxes supplied by the actuator manufacturer are within the scope of this document. In all other casesThis European Standard applies to the electric actuator only. It does not cover: solenoid actuators, electro-hydraulic actuators and electric actuators which are integral in the design of valves. Other requirements or conditions of use different from those indicated inThis document should be agreed between the purchaser and the manufacturer/supplier, prior to order. The terms and definitions applicable toThis European Standard are given in EN 15714-1.
