Electro Mechanical
“PREPEC Electro-Mechanical Rotary Actuator is designed for dependable long life operation."
It is used for operating/regulating the fluid through all types of valves, control and shut off dampers, diverter valves, single and double flap valves, Rack & Pinion Gate, Slide Gates, in Coal, Steel, Chemical and Cement Industries.
The unit is suitable for direct mounting on the valves, dampers, gate body and are manufactured for continuous/intermitted and modulating services.
Salient Features
Range Of Speed: The actuators are available from 4 RPM to 175 RPM but on special request the output speed are available from 0.18 RPM to 300 RPM.
Mountings: Flange or foot mountings with output shaft as per DIN 3210 are designed.
Manual Operation: For easy and effortless operation, declutch able hand wheel is mounted at top with suitable ratio. As soon as the power is ON the clutch will be engaged automatically. The manual operation is regardless of power.
Enclosure: All the actuators are dust and hose – proof as per IP-55/65/66 in special case IP-67 protection are also available.
Gear driven cam for position adjustment: Position limit switches are fixed but adjustable of positioned is controlled by changing the position of cam driven by gears.
Duty Cycles: For frequent ON-OFF and for special application the duty cycles available as per designed by the client specified.
Torque Switches: Torque switches for both directions of rotation are very sensitive.
Position Switches: Position Switches for different application are available through compact geared unit with two or more position.
Local Push Buttons: For special requirement local push buttons are available on the equipment with inbuilt starter.
Corrosion Resistance: All the parts exposed to the air are properly coated/plated to resist corrosion.
Thermistor Control: Embedded thermistor may be provided inside the motor, if desired.
Brakes: Brakes can be provided extremely or electronic type.
Closed/Open Loop Circuit: All the actuator can be used for multi-turn/part turn valves by using proper socket for open and closed loop circuit with feed back of 4mA to 20mA from PLC.
Flange: The actuators are suitable for using different flanges starting from FO5 to FO8 of ISO – 5211:1-1977(E).
Response Time: The response time of actuators are expressed in seconds for full travel and are available in a variety of speeds from 2 to 240 seconds for full travel.
Humidity: The permissible relative humidity of standard actuators is 95%.
