This does not preclude the free use, in the course of implementing the standard, of necessary details such as symbols, and size, type or grade designations. If these details are to be used for any other purpose than implementation enn the prior written permission of BSI must be obtained. Protective paint 1714-2 ISO Table 4 — Environmental corrosion categories Corrosion category Typical environments Exterior Interior C2 low Atmospheres with low level of pollution.
The terms and definitions applicable to this European Standard are given in EN The output drive of multi-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.
Data link layer protocol specifications IEC Your Alert Profile lists the documents that will be monitored.
Classification of environments ISO The transmitter shall enable continuous indication of the valve obturator position at a remote location. Continuous modulating The actuator is required to continuously drive the valve to any position between fully open and fully closed.
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. Compliance with a British Standard ne confer immunity from legal obligations.

The field control device shall meet the specified field bus system. In all other cases this European Standard applies to the electric actuator only. Electric actuators for industrial valves — Basic requirements ICS The input signal may be analogue by a voltage or a current, internally or externally powered, or digitally sourced.
Unless otherwise specified, the manual operating element shall be rotated clockwise to close the valve. Combinations of electric multi-turn actuators and gearboxes supplied by the actuator manufacturer are within the scope of this document. The terms and definitions applicable to this European Standard are given in EN As the voice of the U. NOTE This table may be used to define the corrosion category in order to help the actuator manufacturers to define the surface treatment for corrosion protection.
Combinations of electric multi-turn actuators and gearboxes supplied by the actuator manufacturer are within the scope of this document. BS-EN Industrial Valves – Metallic butterfly valves This standard specifies requirements for butterfly valves having metallic bodies for use in flanged or butt welding piping systems and used for isolat Standards Subsctiption may be the perfect solution.
