How to choose an electric actuator
- Valve type: quarter-turn for ball, butterfly and plug valves; multi-turn for gate, globe and sluice valves; linear for globe control valves.
- Torque: take the valve's breakaway torque and add a safety margin. rated torque is usually about 75% of the listed maximum; for modulating duty allow more.
- Mounting: ISO 5211 flange (F03–F30) and stem size for quarter-turn; ISO 5210 for multi-turn.
- Power supply: AC/DC 24 V, single-phase 110–240 V or 3-phase 380 V.
- Control: on/off (open/close with limit switches) or modulating 4–20 mA / 0–10 V positioning; Modbus on intelligent models.
- Site conditions: IP67 standard, IP68 for submerged or flooded pits, explosion-proof for hazardous areas, fail-safe spring return where the valve must close on power loss.

Frequently asked questions
What is an electric valve actuator?
An electric valve actuator is a motor and gearbox that opens, closes or positions a valve from an electrical signal, so the valve can be operated remotely or by a PLC/SCADA system instead of by hand. Quarter-turn actuators turn ball and butterfly valves 90°, multi-turn actuators drive gate and globe valves, and linear actuators push and pull control-valve stems.
What is the price of an electric actuator in Bangladesh?
The price depends mainly on the output torque, the control type (on/off or modulating 4–20 mA), the power supply, the brand and whether an explosion-proof or waterproof (IP68) version is needed. Send Argonmark the valve type and size, torque, voltage and control signal and we will send a quotation within 24 hours.
Which actuator brands do you supply?
Argonmark currently lists FLOWINN electric actuators (36 models), and can source other brands on request.
How do I choose the right actuator size?
Start from the valve's breakaway torque (from the valve maker) and add a safety margin. Most makers list maximum torque, with rated (continuous) torque around 75% of that; for modulating duty use a larger margin. Then match the ISO 5211 (quarter-turn) or ISO 5210 (multi-turn) flange and the stem size, and pick the voltage, control signal, ingress protection and running time.
Do you supply 24 V DC and 3-phase actuators?
Yes. Many small and medium quarter-turn models are available for AC/DC 24 V and single-phase AC 110–240 V, and larger quarter-turn and multi-turn models for 3-phase 380 V. Check the power supply line on each product page.
Do you have explosion-proof actuators for gas and chemical plants?
Yes, flameproof actuators from 35 to 8,000 N·m. Each product page states the Ex marking given by the manufacturer; ask us for the certificate for your project.
Can the actuator be fitted to my existing valve?
Usually, yes, if the valve has an ISO 5211 or ISO 5210 top flange. Tell us the flange size (for example F07 or F10) and the stem size and shape, and we will confirm whether a mounting bracket or coupling is needed.
