Electric Actuator is a multi-turn electric actuator with embedded intelligent controller. Worm gear and worm are used for electric actuator, to which the gearbox can be added to satisfy users different torque requirements. The actuator is designed to drive the terminal control unit (valve and baffle etc) and has wide applications in industries such as electric power, metallurgy, petroleum, chemical industry, building materials, urban water supply and waste water treatment.

Linear Electrical Actuator is used for high temperature thermic fluid and steam applications. Its important features are its torque is 150 kgf to 1000 kgf, its spilt phase reversible capacitor start-run motor having magnetic rotor acts as prime mover and further manual operation facility is provided to operate valve in case of power failure or during installation of actuator on valves. It is widely used in the fields such as Petroleum, Chemical Industry, Power plant, Metallurgy, Pharmacy, Water treatment vessel, Thermic Fluid lines for furnace & Steam boilers etc.

Rotary Electrical Actuators are used for quarter turn valves automation which is used in power generation, petrochemical plants, oil storage facilities, chemical plants, effluent treatment works etc. The squirrel cage motor is of encapsulated type, on high stall torque and low inherent force for seating & unseating of valves. All motors are integrated with build-in thermal protection. Internal mechanical and electrical components are designed in modular mounting arrangement, and can be easily remove for maintenance purposes. The visual position indicator is directly mounted onto the center drive column to provide the visual position of the valve.

'R' Series Rotary Spring Diaphragm Actuators are available in 3 sizes, i.e., 260, 350, 550 cm2 (40, 55, 85 Sq. Inch). The features are it is suitable for 60° and 90° operation, it has quick response, it has smooth functioning, constant linearity with negligible hysterisis, it has robust design, hand wheel option available and further it is easy to assemble and disassemble from valve.

GOV Series Gas Over Oil Actuator is a gas driven system. It is provided with storage tank for extra operation. It is electrically or mechanically operated. GOV can be installed on DRS, DRV, HYV or any other make of actuators. All pressure parts are as per ‘PED’ and available with certifications. Solenoid operated GOV panel can be used for remote operations.

Electric part-turn actuators by AUMA are used where an automatic, electrically operated movement at a swing angle of less than 360 ° has to be implemented as it is the case for valves like butterfly and ball valves.

Actuators of the SA type range for open-close duty are rated for short-time duty S2 - 15 min. A special version with reduced torque is available for the S2 - 30 min duty. Design features: Torque range from 10 Nm to 32,000 Nm Output speeds from 4 to 180 rpm Limit and torque sensing Available with 3-ph AC, 1-ph AC and DC motors Handwheel for manual operation

Stainless Steel Vertical Pneumatic Actuators are widely used in Chemical, Pharmaceutical, Dairy industries. Its important features are it has fast and reliable quarter turn operations which makes it suitable for use with butterfly, ball and plug valves, it is constructed from corrosion resistant materials, it consists of fully contained spring module to help ensure safety to maintenance personnel and further it is provided with Modular bridge clamp mounting for easy actuator change-out.

Hydraulic Actuators are designed for "on-off" or modulating control of any quarter-turn ball, butterfly, rotary plug or damper style valve applications. Its important specifications are it has supply pressure up to 2,250 psig, its standard temperature rating is -20°F to 210°F and its angular rotation is 90 degrees ±8 degrees. Its important features are its high pressure construction eliminates undesirable regulators and relief valves for supply pressures and further its hydraulic dampening provides smooth “open-close” operation to prevent detrimental valve slamming. Its application area includes Chemical, Pharmaceutical industries.
