Electric actuators STANDARD are the basic actuators manufactured with enclosure IP 54, IP 66, IP 67 and IP 68 (8m/48 hour) and designed for general industrial applications, such as water, chemical, energy industry and etc. They can be installed in usual outdoor environments or inside of buildings, indoor, without explosive atmosphere. The actuators are controlled by the electromechanical control units.
According to the standard EN 15714-2 the electric actuators of STANDARD line meet the classification of the operating mode class A, in other words, they are determined to operation Open-Close, where 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. In order to be handled well they are equipped with standard electromechanical control units consisting of gearings, cams, switches and mechanical position indicator. They are used to control valves, such as ball valves, butterfly valves, gate valves and closing valves as well. They also meet the requirements of the class B inching/positioning, where the actuator is required to occasionally drive the valve to any position (fully open, intermediate and fully closed). They can be also equipped with position transmitters to show
the output position and give feedback. Duty cycle of S2- 10 (15) minutes or S4- 25%, 6-90 c/hour could not be surpassed in neither of these two cases.
