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.

Material and advantages of PP duct valve

The so-called PP pipe actually refers to the material made of polypropylene, which is mainly used in the indoor cold and hot water supply system of buildings. Compared with other materials of pipes, it has good advantages:

1. No corrosion: PP duct valve can withstand the PH value in a wide temperature range, ranging from 1 to 14 high acid and alkali corrosion concentrations.

2. Wear-resistant and non-scaling: PP pipe valves and pipe fittings have a uniform and smooth inner walls, with low flow resistance and no scaling.

3. Reduce vibration and noise: PP pipe valve has excellent sound insulation performance, which can significantly reduce vibration and noise caused by liquid flow.

4. Anti-freeze cracking: PP material has excellent elasticity so that the pipes and pipe sections can expand with the frost heaving liquid without cracking. 5. Anti-condensation, low heat loss: PP material is a poor thermal conductor, reducing condensation and reducing heat loss.

11. Simple installation: PP pipe valve is light in weight, easy to install and operate, and has weldability.

Features:

It is mostly used in cold air or hot air gas pipelines in ventilation and environmental protection projects. The specific industries are chemicals, building materials, power stations, glass products, etc. The sealing ring of the electric air valve is tightly processed with the same high-strength material as the valve body, which has good stability. It also has the advantages of simple structure, small operating torque and light weight, and the characteristics of rapid opening and closing, flexible actions, small operating torque, and large flow capacity are also one of the reasons for the good response of users. It can be applied to the control and adjustment of dust, flue gas, air, and fluids containing suspended particles and thick and turbid and slurry fluids, so it can be regarded as a powerful and practical component in industrial control components.

Uses and characteristics of electric air volume control valve

This valve is made of the same material as the valve body and processed into a sealing ring, which adopts electric or pneumatic transmission. The applicable temperature depends on the material selection of the valve body, and the nominal pressure is ??0.6MPa. Generally, it is suitable for industrial, metallurgical, environmental protection, and other pipelines for ventilation and media flow adjustment. Its main features are:

1. Novel and sound design, unique structure, lightweight, and rapid opening and closing.

2. Small operating torque, convenient operation, labor-saving and dexterous.

6. Use suitable materials to meet the requirements of low, medium and high medium temperatures and corrosive mediums.

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 dispatching valve is formed by cold rolling of 2mm galvanized sheet and then welded by maintenance welding of carbon dioxide gas or processed and welded from general Q235 sheet; the blade is cold-rolled with 1mm galvanized sheet into a corrugated shape, two pieces It is composed of spot welding inserting square shaft, or 2mm G235 steel plate cold forming, single-piece punching inserting square shaft or welding round shaft.

(4) The dispatching valve is divided into manual and electric. According to the materials used, it is divided into four types: carbon steel plate, galvanized plate, aluminum alloy plate, and stainless steel plate. The valve body structure and specifications are the same.
