2.Features

1. The wind valve material is PP and PVC, which is characterized by anti-corrosion, anti-aging, price concessions, easy installation

2. The current manual air valve mold a molding, high strength, good sealing, smooth appearance, low resistance. Its specifications are diameter 63 mm, 75 mm, 90 mm, 110 mm, 160 mm, 200 mm, 250 mm, 315 mm. The diameter of this pneumatic equipment is more than 355 mm which  can be customized.

The following accessories can be selected according to different controls and requirements:

Cut-off accessories: single solenoid valve, double solenoid valve, limit switch echo device.

Adjustable accessories: electric positioner, pneumatic positioner, electric converter.

Air source treatment accessories: air filter pressure reducing valve, air source treatment triple pieces.

Manual mechanism: HVSD manual mechanism

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.

8. 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.

It is widely used in industrial, mining, and civil building HVAC systems to accurately schedule air flow. It is one of the key equipment for controlling ventilation modes in various environments. Its main features are flexible work, low noise, small leakage, reliable structure, safety and convenience.

The above are the main functions and features of the air valve. There are also different types of air valve for different occasions and needs.

Butterfly valve (mainly composed of valve body, valve stem, butterfly plate and sealing ring) is a simple regulating valve, and it can also be used for on-off control of low-pressure pipeline media. Ventilation butterfly valve is a non-closed butterfly valve. Ventilation butterfly valves are used in dusty cold air or hot air gas pipelines of ventilation and environmental protection projects in chemical, building materials, power stations, glass and other industries, as a gas medium to adjust the flow (unit: cubic meters per second) or cut off the pipeline control device. This type of valve should generally be installed horizontally in the pipeline.

(1) The air volume control valve has four specifications when the blade width is all the same. The blade shape is a diamond-shaped double blade, and the blades are soft overlapped, so the sealing performance is excellent.

(2) The valve body frame of the air volume control valve is injection molded from polypropylene material, which has good sealing performance. The product itself has the characteristics of anti-acid and alkali corrosion, and can be widely used in exhaust gas exhaust pipes.

(3) The dispatch valve is divided into manual and electric. The valve body structure and specifications are the same.
