Built-in electric actuators

Functional area

Built-in electric actuators manufactured by ROU Co. of series 821, 822, 823, 824, 825, 876, 854, 792, 793, 794, 795, 797, 768, 798 are designed for operating with shut-off and control valves.
Built-in electric actuator is installed right on the valve trolley and consists of one stage worm gear, electric motor, manual control blocking device, block of limit and position switches.

Electric actuators manufactured for domestic (Russian) markets are available in modifications for moderate climate zones (U), atmosphere type P, with placement category 3 under GOST 15150-69 standard.
Electric actuators manufactured for export markets are available in modifications for moderate (U) and tropical (T) climate zones, atmosphere type P, with placement category 3 under GOST 15150-69 standard.
Electric actuators are designed for use in closed space with the following conditions:
• Outside environment temperature, °С – 40
• Air environment – non-explosive
• Elevation – up to 1000 m;
• Relative humidity 80% at 20°С; 50% at 40°С

Setting up

Built-in electric actuator is installed right on the valve trolley and consists of one stage worm gear, electric motor, manual control blocking device, block of limit and position switches.

Technical characteristics and operation:

Electric actuator is used for the following operations:
• Local and remote control of the valve from the control room, gate opening and closing of the valve by pressing the “close” and “open” buttons and stopping the
actuator at any moment be pressing the “stop” button;
• Manual control of the valve;
• Automated electric motor shut down when the gate of the valve reaches any of its end positions;
• Automated electric motor shut down when the rotational torque on the valve (electric motor) spindle reaches dangerous values (higher than preset values, adjusted by overcurrent relay). Shut down is possible in any of the end positions, as well as in any position between them;
• Visual warnings;
• Local adjustment of the gate of the valve;
• Remote adjustment of the gate of the valve with the help of sensor inside the actuator and receiver device in the control room;
• Electric motor blocking during manual control mode of the valve-actuator;
In case of manual control of the valve, when rotating the flywheel of the actuator to the right the valve gate closes, to the left – opens. Torque is transferred through roll of worm gear drive.

Manufacturing and supply in accordance with TS 3791-001-71228244-2011.
