The advantage of the variable air volume venturi valve is that the system has good anti-interference ability. Compared with the traditional butterfly valve, its accuracy can reach only 5%, and it can also achieve a high adjustment ratio that cannot be achieved by traditional valves. For example, Desai Zhiyan The tsirosmax variable air volume venturi valve can reach a turndown ratio of 20:1, which is relatively prominent in the industry products. In theory, the response time of the Venturi valve can be less than 1 second, and it will not be affected by other external pressures.

In general, different laboratories have different ventilation requirements, and the choice of valves should be tailored to local conditions. If you are not sure whether to choose a butterfly valve or a Venturi valve, you can also consult the designers or experts of Desai Zhiyan to ensure targeted design and ensure the safety and normal operation of the laboratory. On this basis, we must also choose high-quality and well-known manufacturers, such as Shenzhen Xicheng Environmental Protection Technology Co., Ltd., which can save costs for users and improve comfort on the basis of high quality.

1. The role of water balance. The air volume distribution in various ventilation systems is reasonable, ensuring reliable fresh air distribution in different areas.

2. The function of energy-saving and precise control of air volume. On the premise of ensuring the fresh air volume, the system runs energy-saving and low-consumption

3. It is widely used in the industrial waste gas treatment industry, which can accurately control waste gas emissions and prevent the backflow of toxic waste gas.

4. The effect of reducing noise. It can effectively reduce wind noise and other noise in the air duct, especially in the exhaust system of industrial production and office buildings, replacing exhaust fans, significantly reducing noise, saving energy, and maintaining continuous ventilation.

The constant air volume regulator with nothing to do with the pipeline pressure is used in the central fresh air system and exhaust system to effectively ensure the continuous new air volume and exhaust volume effectively and accurately control the air volume and reduce noise. They are usually used in a large area in the air duct system of the central fresh air system and exhaust system of hotels, hospitals, office buildings, and other places to replace traditional manual valves and exhaust fans.

The air volume control valve has a range:

The electric air volume control valve is suitable for industrial waste gas treatment, civil building HVAC systems, ventilation equipment in school laboratories, and hospital ventilation and exhaust systems. It is one of the vital equipment to control ventilation modes in various environments. Its main features are flexible operation, low noise, small leakage (closed type leakage> 0.5%), wide operating temperature range, reliable structure, safe and convenience.
