It is therefore essential that the correct size of actuator is selected together with any associated ancillary equipment.

Connections shall be clearly identified with numbers 2 and 4in accordance with ISO The output drive of part-turn actuators may be an integral part or a removable component to allow it, when necessary, to be machined to suit the driven component of the valve. To qualify a range of actuators, of the same design and of the same action, manufactured under the same process and from the same or equivalent e, the type tests may be carried out on a limited number of sizes by applying ej following rule: This publication does not purport to include all the necessary provisions of a contract.

It is the constant aim of BSI to improve the quality of our products and services. The relationship between air volume V and dimensions of connections “2” and “4” are given ej guidelines.

The position, location, orientation and form of the pressure connections shall be established by the manufacturer. Pneumatic part-turn actuatorsfor industrial valves — BasicrequirementsICS A version in any other language made by translation under the respons eb of a CEN member into its own language and notified to the CEN Management Centre has the same status as the official versions.

If the slot is used as a position indicator it shall be parallel to the pipe axis when the valve is open. The position, location, orientation and form of the 15714- connections shall be established by the manufacturer.
