damper

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.

1. There is no connecting rod, bolt, etc. inside, so it works reliably and has long service life 2. The valve body and valve plate are welded with high-quality carbon steel plate or stainless steel plate. It has the advantages of simple structure, small flow resistance, light weight, flexible rotation, long service life and convenient operation and maintenance

Manual, electric, pneumatic series of 304SS Butterfly Damper Valve are made of steel plate welding, with the characteristics of short structure size, light weight and convenient installation. The 304SS Butterfly Damper Valve 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. The 304SS Butterfly Damper Valve can be equipped with a variety of driving devices, such as manual device, worm gear transmission device, pneumatic device, electric device. Ventilation butterfly valve is widely used in metallurgy, petrochemical, electric power, building materials, mining and other industrial pipelines, to control or regulate medium gas
