NF ISO 5115, E29-407 (11/2023)

This document applies to part-turn motorized valve assemblies comprising a valve (e.g. ball valves, butterfly valves and cone valves), an actuator and, where applicable, a mounting kit supplied as a set. It defines the design characteristics necessary for actuating valves, the responsibilities for providing the required information and the tasks to be carried out, to ensure the appropriate sizing and selection of an actuator and kit assembly, as well as its connection to the valve. It applies to pneumatic, hydraulic, electro-hydraulic and electric actuators. An electric actuator connected to a gearbox, as defined in ISO 5211, is included in the scope of this document. Valves controlled by lever or manual reducer are excluded.
