23、ument provides basic requirements for electric valve actuators, used for on-off and control valves. 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 th

24、e actuator manufacturer are within the scope of this document. In all other cases this European Standard 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

25、conditions of use different from those indicated in this document should be agreed between the purchaser 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 ar

28、ors are classified per type, duty and action as detailed below. 3.2 Type: Part-turn, multi-turn or linear 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

29、a part-turn gearbox can be considered, for the sake of this European Standard, a part-turn actuator. 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

30、 multi-turn gearbox can be considered, for the sake of this European Standard, a multi-turn actuator. 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 thi

31、s European Standard, a linear actuator.

32、ire travel from the fully open position to the fully closed position or vice-versa. 3.3.3 Class B: Inching/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 frequentl

33、y drive the valve to any position between fully open and fully closed. 3.3.5 Class D: Continuous modulating 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 ext

34、ernal power, the actuator remains in the position achieved before loss of power. 3.4.2 Fail safe action On 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 li

35、fe endurance criteria as defined in Annex A. The endurance of modulating and continuous modulating actuators shall be based on consecutive starts spread over an intermediate stroking span of maximum 30 % of full travel.
