Control valves in combination with the attached auxiliary are important elements in chemical and process plants, some with a safety function.

This standard sets general calculation methods, recommendations and requirements for pneumatic, electrical and electro-hydraulic actuators to enable a reliable and safe operation in industrial plants.
