Frequently Asked Questions

What is the DUNGS EMx-... actuator used for?

The DUNGS EMx-... actuator is designed to operate dampers, butterfly valves, and similar devices in industrial combustion and airflow systems. It provides precise flow control with two-position, three-point stepping, or analog control methods, making it suitable for burners, boilers, and HVAC applications.

What are the specifications of the DUNGS EMx-... actuator?

DUNGS EMx-... actuators offer torque from 16 in. lb. to 450 in. lb., with 90° or 180° rotation. Models include two-position spring return (EMA), position proportioning with 100 Ohm slidewire feedback (EMP-4..-1), potentiometer slaved proportioning (EMP-4..-2), and 4-20 mA input proportioning (EMP-4..-5). All are UL listed.

Where to buy DUNGS EMx-... actuators in Singapore?

You can source DUNGS EMx-... actuators through 3G Electric in Singapore. We handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on your required model and torque.

How to select the right DUNGS EMx-... actuator for my application?

Select the DUNGS EMx-... actuator based on required torque (16 to 450 in. lb.), control method (two-position, proportioning, or 4-20 mA), and stroke timing. For dampers or butterfly valves, match the rotation angle (90° or 180°) and ensure voltage compatibility (110-120 VAC). Consult the datasheet for ambient temperature range.
