1.Product Introduction

Manual regulating valve is installed on the supply and return air ducts of ventilation and air conditioning adjustment systems. It is usually open. In the event of a fire, when the flue gas temperature in the duct reaches 70 °C, it is closed, and it can meet the requirements of smoke leakage and fire integrity within a certain period of time. A valve that acts as a smoke and fire barrier.

Fire dampers are generally composed of valve bodies, vanes, actuators and temperature sensors.
