What is a damper actuator?

Damper Actuator is a motor-operated rotary actuator in which speed reducer, motor, limit switches, overload switches, opening transmitter and manual handling mechanism are united.

How do I choose a damper actuator?

So the first step in selection of the proper damper actuator is to find the damper’s square footage AREA. A simple formula of Width X Height divided by 144 will give you the square footage of a damper. Example: The damper in question is 45 inches X 23 inches using the formula.

How do I lock my Belimo actuator?

To lock the actuator in the required position, flip the switch to the locked position that is located to the right of the crank on the CCW side of the actuator (left of the crank on the CW side).

How do you calculate torque for a damper actuator?

Torque Formula:

  1. Damper Area (Ft2) =
  2. Torque Factor ( )
  3. Required Torque (LbIn) = Damper Area (Ft2) * Torque Factor * Torque Factor ( )

What is the most common type of damper?

The most common type of static fire damper is a curtain damper. A folded ‘curtain’ is held up by a thermal element/fusible link. Upon reaching a certain temperature, the link melts and the damper falls shut by means of gravity.

How does a spring return damper work?

An electric spring return damper is a device powered by a motor that converts electrical energy to mechanical torque. The electric energy is used to actuate multi-turn equipment, such as gate or globe valves. A scotch yoke actuator converts linear motion into rotational motion.

How does a spring return actuator work?

Spring return actuators have either air or liquid supplied to one side of the piston, and the energy to move the valve comes from a spring on the opposite side. This pressure of the air or liquid opens or closes the valve, and a spring creates the opposite motion.
