Electric Volume Control Damper

Electric damper is composed of electric actuator and damper. Modulating type electric damper can modulate the opening degree of the damper, and control the blast capacity. Two positions type electric damper has the on-off and start-up function.

2. There are square damper and round damper.

square damper: X long, 160X130~1000X500 wide

round damper: DN100~DN400

Actuator Model

AS10, AS25, BS60, A+RS100, B+RS160, B+RS250, B+RS400, B+RS600,B+RS800,B+RS1000,B+RS1200 electric actuator......

We can offer other series actuators to match the damper, please refer to the actuator category.

Main Advantages

1. The electric actuator is manufactured with introduced technology of new generation.

2. Integrated product with high accuracy
3. Bidirectional over torque protection function
4. Over travel protection function of the electric actuator
5. Signal interruption protection function of valve actuator
6. Automatic switchover function of motorized actuator

7. Electric braking function of the electric motor

8. The high-performance servo motor is equipped with overheat, phase cutoff protection functions

9. Relatively strong resistance to interferences.
