EN 15714-3:2009 Industrial valves - Actuators - Part 3: Pneumatic part-turn actuators for industrial valves - Basic requirements – Proposal to revise

What is it?:
This European Standard provides basic requirements for pneumatic 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 pneumatic actuators which are integral parts of control valves.

Why Is it Important?:
The proposed revision by Germany is to extend the existing connection sizes by the nominal sizes ¾” and 1” air connections. This is necessary to promote the development of larger solenoid valves or other sandwich attachments.
