BS EN 15714-2:2009EN 15714-2:2009 (E) 5 1 Scope This document provides basic requirements for electric valve actuators, used for on-off and control valves.
23、It includes guidelines for classification, design, enclosure and corrosion protection, and methods for conformity assessment. Combinations of electric multi-turn actuators and gearboxes supplied by the actuator manufacturer are within the scope of this document. In all other cases this European Stan
24、dard applies to the electric actuator only. It does not cover: solenoid actuators, electro-hydraulic actuators and electric actuators which are integral in the design of valves. Other requirements or conditions of use different from those indicated in this document should be agreed between the purch
25、aser and the manufacturer/supplier, prior to order. The terms and definitions applicable to this European Standard are given in EN 15714-1. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited a
26、pplies. For undated references, the latest edition of the referenced document (including any amendments) applies.

28、inear 3.2.1 Part-turn: An actuator which transmits torque to the valve for less than one revolution. It does not have to be capable of withstanding thrust. 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.
29、 3.2.2 Multi-turn actuator: An actuator which transmits torque to the valve/gearbox for at least one revolution. It may be capable of withstanding thrust. A combination of a multi-turn actuator plus a multi-turn gearbox can be considered, for the sake of this European Standard, a multi-turn actuator
30、. 3.2.3 Linear actuator: An actuator which transmits thrust to the valve for a defined linear stroke. A combi-nation of a multi-turn actuator plus a linear drive can be considered, for the sake of this European Standard, a linear actuator. BS EN 15714-2:2009EN 15714-2:2009 (E) 6 3.3 Actuator duty cl
31、assification 3.3.1 General Basic design requirements for actuator duty classification are given in 4.1 and 4.7.2. 3.3.2 Class A: On-off The actuator is required to drive the valve through its entire travel from the fully open position to the fully closed position or vice-versa. 3.3.3 Class B: Inchin
32、g/positioning The actuator is required to occasionally drive the valve to any position (fully open, intermediate and fully closed). 3.3.4 Class C: Modulating The actuator is required to frequently drive the valve to any position between fully open and fully closed. 3.3.5 Class D: Continuous modulati
33、ng The actuator is required to continuously drive the valve to any position between fully open and fully closed. 3.4 Action on loss of external electric power 3.4.1 Standard action On loss of external power, the actuator remains in the position achieved before loss of power. 3.4.2 Fail safe action O
34、n loss of external power, the actuator is able to operate the valve to a pre-defined safe position. 4 Design requirements 4.1 Endurance 4.1.1 General The actuator shall be designed to meet the life endurance criteria as defined in Annex A. The endurance of modulating and continuous modulating actuat
35、ors shall be based on consecutive starts spread over an intermediate stroking span of maximum 30 % of full travel.
