MOKA – electric part-turn actuator

Usage

Electric part-turn actuator MOKA is designed for special valves installed out of the containment of nuclear power plants with reactors type VVER and in attended spaces of nuclear power plants with reactors type RBMK. According to ranking within safety classes and purpose of their use, the actuators MOKA belong to the elements: 2N; 3N; 4N; 2Z; 2P; 2O; 2NZ; 2NO according to OPB-88/97 and make it possible to control shut-off and regulation valves by reversible rotary motion with turning angle of the output part up to 90°, including cases requiring tight closure in limit positions. A typical example of using is control of ball valves, flaps, and similar devices in the regime of remote control and automatic regulation. The actuators are installed directly on a controlled organ.

MOKED – electric part-turn actuator

Usage

Electric part-turn actuator MOKED is designed for shifting control elements by a reversible rotary motion with the turning angle of the output part 90°, including cases when tight closure in end positions is required. Typical example of using is control of ball and flap valves in similar installations in the regime of remote control as well as automatic regulation. The electric actuators MODACT ® MOKED are mounted directly on the controlled element.

Description

Electro-mechanical control board is replaced with the electronic system DMS2 or DMS2 ED. Both systems scan position of the output shaft and torque of the electric actuator by contact-free magnetic sensors. The sensor of the output shaft position is absolute and does not require any backup power supply in case supply voltage is disconnected during operation of the electric actuator. Both systems can be set and monitored by a computer with controlling programme or manually without a computer.
The more simple system DMS2 ED substitutes electromechanical parts and/or provides for controlling the electric actuator by input analog signal as in the version Control.

The system DMS2 enables the electric actuator to be used for two-position and three-position regulation or to be connected to the industrial bus bar Profibus.
