electrically powered device attached to the valve by bolting for the purpose of applying torque (3.5)
and/or thrust to open and close and/or control a valve
3.2
part-turn actuator
actuator which transmits torque (3.5) to the valve for less than one revolution, and does not need to be
capable of withstanding operational thrust
Note 1 to entry: In this document, a combination of a multi-turn actuator (3.3) plus a part-turn gearbox (3.15) is
considered as a part-turn actuator

detailed below.

4.2 Type
There are three types of actuators:
— part-turn actuator;
— multi-turn actuator;
— linear actuator.
4.3 Actuator duty classification
The basic design requirements for electric actuators duty classification are given in Table 1.
The electric actuator shall be designed to meet the endurance criteria defined in Table 2, Table 3 or
Table 4.
Table 1 — Duty classification
Class Duty Definition
A On-off The electric actuator is required to drive the valve through its stroke
from the fully open position to the fully closed position or vice-versa.
B Inching/positioning The electric actuator is required to occasionally drive the valve to any
position (fully open, intermediate and fully closed).
C Modulating The electric actuator is required to frequently drive the valve to any
position between fully open and fully closed.
D Continuous modulating The electric actuator is required to continuously drive the valve to
any position between fully open and fully closed.
4.4 Action on loss of external electric power
4.4.1 Stay put action
On loss of external power, the actuator remains in the position achieved before loss of power.
4.4.2 Fail-safe action
4.4.2.1 Electric fail-safe action
On loss of external power, the actuator is able to operate the valve to a predefined position using stored
electrical energy.
4.4.2.2 Mechanical fail-safe action

mechanical energy.
