1. Product Introduction


Constant air volume valve is a mechanical self-operated device suitable for ventilation and air conditioning systems that require constant air volume. The air volume control of the constant air volume valve does not require external power. It relies on the air force in the air duct to locate the position of the control valve, so as to maintain the air flow at the preset flow rate in the entire pressure difference range.

3. Product Feature And Application


The constant air volume valve is an automatic mechanical mechanism that does not require external power. An additional electric actuator can be added to change the flow setting through remote control signals. The constant air volume valve can be used in air supply and exhaust systems. The working temperature is generally 10 to 50°C, and the pressure difference range is 50 to 1000 Pa, that is, at least a 50 Pa pressure difference is applied before and after the valve, otherwise the constant air volume valve will not work. This should be noted, because the wind pressure value of the fresh air unit of the fresh air system is generally not large. The fixed air volume valve is not limited by position when installed, but the shaft of the valve plate should be kept level. Generally, a straight inlet air duct with a distance of 1.5 times the long side of the valve and a straight outlet air duct with a distance of 0.5 times are required.
