Salient Features:

• Excellent non-locky features : It is observed that when the torque switches fail due to various reasons the equipments are jammed and require dismantling/handcranking. In PREPEC Actuators all these problems are overcome by its superior design. It can be instantly released by switching from control centre.
• Range of speed : The actuators are available from 4 r.p.m. to 175 r.p.m., but on special request the output speed are available from 0.18 r.p.m. to 300 r.p.m.
• Mountings: Flange or foot-mountings with output shaft as per DIN3210 are designed.
• Manual Operation : For easy and effortless operation, declutchable hand wheel is mounted at the side or 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 1P-55 of IS-4691 in special case IP-67 protection are also available.
• Hammer blow mechanism: Specially designed hammer blow mechanism acts to release sitting pressure instantly.
• Gear driven cam lor position adjustment: Position limit switches are fixed in its own position, but adjustment of position 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 2 or more position.
• Local push buttons : For special requirement local push buttons are available on the equipment.
• Space Heaters : Space heaters can be provided inside the switch compartment and also in the motor, if desired.
• Corrosion resistance : All the parts exposed to the air are properly coated/plated to resist corrosion.
• Thermistor Control: Embeded thermister may be provided inside the motor, if desired.
• Phase discriminator: All the limit switches are dependent on direction of rotation. For correct direction of rotation, phase discriminators can be incorporated.
• Terminals: All the wires are wired up to a terminal box for easy terminal connection.
• Brakes: Brakes can be provided externally 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 4 MA to 20 MA for PLC.
• Flange : The actuators are suitable for using different flanges starting from F07 to F40 of IS-9334.
• 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 starndard actuators is 95%.
• Special application : Actuators are available for special applications like Explosion Hazardous area as per IS-2148-1968 and also for use of nuclear generating station for gas group IIA, IIB and HE.
