(1) The Rectangular Motorized Duct Damper 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.

2.the characteristics of the Rectangular Motorized Duct Damper

(1) The takeover standard of the split multi-leaf air volume dispatching valve is the same as the rectangular air duct standard of the national ventilation duct standardization.

(2) The blades of the air volume dispatching valve are side-opening and forward-opening, which are used as dispatching valves in ventilation, air dispatching and air purification systems.

(3) According to the test, the air-tightness of the air volume dispatching valve is good, and its relative air leakage is about 5%, and the dispatching performance is good.

3.the scope of application of the Rectangular Motorized Duct Damper

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.

When the ball PP valve rotates 90 degrees, it should show a spherical surface at the inlet and outlet, so as to close the valve and cut off the flow of the medium.

Advantages of PP ball valve：

The PP ball valve is not restricted by the installation direction, and the flow direction of the medium can be arbitrary. The fluid resistance is small, and the full-bore ball valve basically has no flow resistance.

The PP ball valve has a simple structure, relatively small size, light weight and easy maintenance.

Close and reliable. It has two sealing surfaces, and the current sealing surface materials of ball valves are widely used in various plastics, which have good sealing performance and can achieve complete sealing. It has also been widely used in vacuum systems.

PP ball valve is suitable for frequent operation, opening and closing quickly and lightly. It is easy to operate and open and close quickly. It only needs to rotate 90° from fully open to fully closed, which is convenient for remote control.

The maintenance is convenient, the structure of the ball valve is simple, the sealing ring is generally movable, and it is convenient to disassemble and replace.

PP ball valve has good sealing performance. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when the medium passes.

It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure.

Because the PP ball valve has wiping properties during the opening and closing process, it can be used in media with suspended solid particles.

9. PP ball valve has low fluid resistance, no vibration and low noise.

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.
