Damper

1. It is convenient and quick to open and close, with low fluid resistance and easy operation.
2. Simple structure, small size, short structure length, small volume, light weight, suitable for large caliber valve.
3. It can transport mud and store the least liquid at the pipe mouth.
4. Under low pressure, good sealing can be achieved.
5. Good regulation performance.
6. When the valve seat is fully open, the effective flow area of the valve seat channel is large and the fluid resistance is small.
7. The opening and closing torque is small, because the butterfly plates on both sides of the rotating shaft are basically equal to each other under the action of medium, and the direction of torque is opposite, so it is easier to open and close.
8. The sealing surface materials are generally rubber and plastic, so the low-pressure sealing performance is good.
9. Easy to install.
10. The operation is flexible and labor-saving. Manual, electric, pneumatic and hydraulic modes can be selected.

1.Air Duct Valves is made of steel plate welding, which has the characteristics of short structure size, light weight and convenient installation.

2.Air Duct Valves has small driving torque, flexible opening and closing, and convenient operation. There is no visible gap between the sealing pairs and the leakage rate is small. The expansion gap between butterfly plate and valve body is large, which can effectively prevent the jamming caused by heat expansion and cold contraction

There is no connecting rod, bolt and other components in the part, so there will be no component problems in the process of use, so the failure rate is very low.

Because there is a large gap between the butterfly plate and the valve body of the ventilation butterfly valve, there is enough expansion space, so in the process of use, it can effectively prevent the thermal expansion and cold contraction caused by the temperature change, and the butterfly plate will not be stuck

The industrial high temperature butterfly valve is characterized by high temperature resistance, large nominal diameter, carbon steel valve body and metal ring instead of rubber ring. Large high temperature butterfly valve is made of steel plate welding, which is mainly used for flue gas duct and gas pipeline with high temperature medium.

1. The ventilation butterfly valve has reasonable design, unique structure, light weight and quick opening and closing.
2. ventilation butterfly valve operating torque is small, easy to operate, labor-saving and dexterous.
3. Suitable materials are used to meet the requirements of low, medium and high medium temperature and corrosive medium.
4. There is no connecting rod, bolt, etc. inside, ventilation butterfly valve works reliably, has long service life and is not affected by the flow direction of medium

1. Full size control, fine workmanship and long service life

2. High quality material, strong rigidity, strong durability, not easy to rust in water, and strong corrosion resistance

3. Our factory has strict quality inspection system, and the factory products are tested in multiple ways to prevent quality problems

The main body of the valve is welded structure. The disc is composed of several shutter plates which move around their respective rotating shafts. The shaft end is sealed with flexible graphite braided packing, which has the characteristics of high temperature resistance and self lubrication.
The working principle of the valve is that the output torque of the driving device is transmitted to each valve shaft through the connecting rod mechanism, and the rotation of each valve shaft drives the rotation of their respective shutters to change the cross-sectional area of the pipeline, so as to achieve the function of cutting off the medium in a large area, reducing the medium pressure or regulating the medium flow, and the adjustment angle is 0-90 °.
It has the advantages of simple structure, small flow resistance, light weight, flexible rotation, long service life and convenient operation and maintenance.

1. A single shaft driven baffle structure is adopted, and a sealing chamber is designed in the middle of the double-layer blades to introduce the sealing air into the baffle plate, so that the sealing air isolation layer is formed between the double-layer baffles to block the flue gas flow.
2. Connecting rod mechanism is designed outside to make several blades open or close synchronously.
3. The design structure is reasonable, the blade rigidity is good, and the operation is stable and reliable

The structure of the Motorized Electric Control Air Damper is welded by using the center line butterfly plate and short structure steel plate, so there are no connecting rod, bolt and other components in its internal part, so there will be no component problems in the use process, so the failure rate is very low. It's very convenient to use. It is a reliable Motorized Electric Control Air Damper. And because its sealing system is metal sealed.
