Emtork Electric Actuators For Valves & Dampers

The "Emtork" Electric Actuators are electromechanical units used for operating the final control elements like valves or dampers to control the flow of fluids flowing thru the pipes or ducts. The specific advantages of using these units are :

Ease of operation.
Remote control facility.
Proportional action of final control element in close loop system.
Attaining & holding the desired preset position of the valve/damper.
Various indications & alarms are available on the remote control panel & also on the unit.
Emergency manual operation possible in case of power failure.
Works on most convenient & easily available source of energy i.e. electricity.
Models available to cover wide range of valves & dampers.
Units with Integral starter will save cost of cables.
Units with Electronic controller will facilitate field programming.

Design

The Basic design of the Emtork Actuator consists of an electric motor, reduction gear unit and control compartment.
Various models have been developed to suit operating torque, speed, process parameters, area of operation etc.
Additional supplementary spur and worm gear boxes are offered to get higher operating torques and quarter turn motion.
Linear motion actuators have been developed to impart the required thrust to operate globe valves.
The models are available for on / off and regulating duly and also for hazardous area application.
