HVAC Fire Damper Actuator Five Speed Regulation Signal Feedback Air Valve Controller Driver

Product features:

1. Manual reset

Manually reset, control the valve to open, activate the 70 ºC or 280 ºC fuse, and control the valve to close.

A temperature sensor with a nominal operating temperature of 70 ºC is used for fire dampers.

A temperature sensor with a nominal operating temperature of 280 ºC is equipped for smoke exhaust fire dampers.

2. Output signal feedback

Output open and close position feedback signals (passive signals) and only provide one set of open and close feedback signals, where the close signal can only be output after the temperature sensor fuses.

3. Five level air volume adjustment

Product parameters:

The DL-V-4 fire damper actuator is installed on the fire damper.

Manually reset and control the valve to open.

The temperature sensor fuses and controls the valve to close.

Adjustable valve opening angle.

Output open and close position feedback signals (passive signals), where the close signal can only be output after the temperature sensor is blown.

Torque: 8.5Nm

Remarks:

1. The main body of the actuator is the same. When used for fire dampers, a temperature sensor with a nominal operating temperature of 70 ºC is equipped, and when used for smoke exhaust fire dampers, a temperature sensor with a nominal operating temperature of 280 ºC is equipped.

When the actuator is used for normally open valves, it opens the valve counterclockwise and closes clockwise.

3/This actuator only provides one set of opening and closing feedback signals.
