Spring return type air valve actuator

The spring return damper actuator is a special type of actuator that can automatically restore the damper to the preset open or closed position through the built-in spring mechanism when the power is off or the control signal is lost. This actuator is widely used in industrial automation and building ventilation systems, especially in situations where the safety and reliability of the system need to be ensured.

1. Product Features

Spring return function:

The spring return damper actuator has a built-in spring mechanism that can automatically reset when the power is off or the control signal is lost. This function ensures that the damper can be quickly closed or opened in an emergency to maintain the safety and stability of the system.

High-precision control:

This type of actuator is usually equipped with a high-precision position sensor and control system to achieve precise control of the damper opening. By receiving analog or digital signals from the controller, the actuator can accurately adjust the damper opening to meet the system's requirements for air flow and pressure.

Multiple torque categories:

Depending on different application requirements, the spring return damper actuator provides multiple torque categories (such as 5Nm, 10Nm, 20Nm, etc.) to accommodate dampers of different sizes and weights.

Easy to install and maintain:

Actuators usually adopt modular design, which is convenient for users to install and maintain. At the same time, some models are also equipped with removable wiring covers and unified wiring standards, making installation and wiring faster and more convenient.

Overload protection function:

In order to protect the actuator and damper from damage, spring return damper actuators usually have overload protection function. When the actuator is subjected to excessive load, it can automatically cut off the power supply or gas source to prevent equipment damage and accidents.

2. Application scenarios

HVAC system:

Spring return damper actuators are widely used in HVAC systems. They can drive various valves that require spring return fault protection control to ensure that the damper can be quickly closed in the event of power failure or system failure to prevent hot and cold air mixing and energy loss.

Ventilation system:

Spring return damper actuators also play an important role in the ventilation system of buildings. They can control the distribution of fresh air volume and exhaust air volume to ensure the circulation and renewal of indoor air. At the same time, in emergency situations such as fire, the actuator can quickly close the fire damper to cut off the channel for the spread of fire.

Industrial production lines:

In some industrial production lines that have high requirements for air flow and pressure, spring return damper actuators are also widely used. They can accurately control the opening of the damper to ensure that the air flow and temperature control during the production process are in the best state.
