The basic structure of the air volume regulating valve is to place a baffle at the center of the air duct, and the valve plate can rotate around an intermediate shaft parallel to the valve plate for communication By using an electric motor to control rotation, it becomes an electric multi blade air volume control valve. Air volume control valves are generally divided into the following types:

(1) Split multi leaf regulating valve

(2) Butterfly valve (single leaf regulating valve)

(3) Open the regulating valve in sequence

Function and scope of application of electric control valve
The main characteristics of electric air volume control valve are:

1) The size of the connecting pipe for the multi blade air volume control valve is the same as the rectangular duct size specified in the national ventilation duct standardization.

(2) The blades of the air volume regulating valve are split and open, and are used as regulating valves in ventilation, air conditioning, and air purification systems.

(3) Through experimental testing, it has been determined that the air tightness of the air volume regulating valve is good, with a relative air leakage rate of about 5% and good regulating performance.

Function and scope of application of electric control valve
Electric control valves are suitable for HVAC systems in industrial, mining, and civil buildings, regulating air flow and being one of the key equipment for controlling ventilation modes in various environments. Its main characteristics are flexible operation, low noise, small leakage, wide working temperature range (sealed leakage<0.5%), reliable structure, and safety and convenience.
