The following is optional: Classification of environments ISO Need more than one copy? BSI also holds the copyright, in the UK, of the publications of the international standardization bodies.
An actuator which transmits torque to the valve for less than one revolution. This standard is also available to be included in Standards Subscriptions. This is usually associated with critical valve applications e. A combination of a multi-turn actuator plus a linear drive can be considered, for the sake of this European Standard, a linear actuator. This may include the local control station as described in 5.
BS en Industrial Valves Actuators It is therefore essential that the correct size of actuator is selected together with any associated ancillary equipment. The testing power supply shall be properly documented in the test documentation of the manufacturer.
The controls may be an integral part of the actuator or, in case of space restrictions or adverse environmental conditions e. Verification of combination thrust shall be available but may be derived via calculation based on linear drive performance data. It is incorporated by Royal Charter.
Above 32 5 5 30 N. Tests — Test B: For multi-turn actuators the operating speed shall be provided in revolutions per minute r.

C5-I very high — industrial Industrial areas with high humidity and aggressive atmosphere. Combinations of electric multi-turn actuators and gearboxes supplied by the actuator manufacturer are within the scope of this document. A combination of a multi-turn actuator plus a part-turn gearbox can be considered, for the sake of this European Standard, a part-turn actuator.
When requested, for particular applications, manual operation may be omitted. This standard is not included in any packages. Table 4 — Environmental corrosion categories Corrosion category Typical environments Exterior Interior C2 low Atmospheres with low level of pollution.
It includes guidelines for classification, design, enclosure and corrosion protection, and methods for conformity assessment.
BS EN 15714-2:2009
If the device can be connected electrically to an external circuit, the electrical rating shall be stated in the technical documentation. Tests — Test A: Standards E from ANSI provides a 155714-2, multi-user solution for accessing standards.
We would be grateful if anyone finding an inaccuracy or ambiguity while using this British Standard would inform the Secretary of the technical committee responsible, the identity of which can be found on the inside front cover. Add to Alert PDF.
The drive shall be designed so that the manual operating element cannot be driven by the motor. This document provides basic requirements for electric valve actuators, used for on-off and control valves. The type tests to be 51714-2 shall be those given in Table 9. It does not have to be capable of withstanding thrust.
