Features of air volume control valve:
1. Pressure independent control: the valve body in the valve body to install mechanical pressure compensation components, according to the air inlet and outlet pressure pressure for automatic pressure compensation to ensure that the wind valve in the static pressure changes to maintain a constant set of air flow; Pressure drop 150Pa ~ 750Pa within the scope of pressure to achieve independent control;
2. Accurate air flow control: through the air flow speed controller component positioning, air volume can be quickly adjusted, air volume control accuracy of ± 5%;
3. Air volume adjustment control range: air volume 50m3 / h ~ 1100m3 / h;
4. Fast response: response time to control signal and duct static pressure change: <1 second;
5. Anti-dust, maintenance-free: Compared with the conventional butterfly valve similar products, because this series of products without air flow (or pressure) sensor, so the sensor caused by dirty plug system failure caused by security incidents, improve product stability And durability.
6. highly anti-corrosion treatment: the use of PP plastic body material, is the product can be high-intensity corrosion conditions in the long-term safe operation;
7. Control mode switching and remote communication function: This product selection PLC programmable controller, with control mode switching function (software with a variety of operating modes, just set to change the valve running control state) and remote communication function.
8. High reliability, high quality price, courteous service: domestic quality products, reliable operation, quality and cheap, provide 24-hour service.
Applications:
1. Constant air volume control (CAV series): suitable for static pressure changes in the case, to maintain the set air volume of the occasion.
2. VAV control (VAV series): for closed-loop feedback variable air volume control occasions.

The scope of application of the air valve

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.

Scope of application of vav variable air volume butterfly valve

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.

Structural characteristics of the air valve

(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.

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

Electric air volume control valve actuator

Adopt the new series of GT electric actuators, with double-acting and single-acting (spring reset), gear transmission, safe and reliable; large-diameter valves adopt series AW-type pneumatic actuators with fork drive, reasonable structure, and ample output torque. There are double-acting and single-acting.

1. Geared double pistons, ample output torque, and small volume.

2. The cylinder is made of aluminum gold material, which is light in weight and beautiful in appearance.

3. Manual operating mechanism can be installed on the top and bottom.

4. The rack-and-pinion connection can adjust the opening angle and rated flow.

5. The actuator can be equipped with electrical signal feedback instructions and various accessories to realize automatic operation.

6. IS05211 standard connection provides convenience for product installation and replacement.

7. The joint screws adjusted at both ends can make the standard product have an adjustable range of ??4?? between 0?? and 90??. Ensure the synchronization accuracy with the valve.
