Damper

Many blades, low noise, light weight, small operating torque, low leakage rate, especially suitable for large diameter, large flow, low pressure difference range.

1. Leakage less than or equal to 1%

2. The driving ways can be manual drive, worm gear drive, pneumatic drive and electric drive

3. Carbon Steel Butterfly Air Damper Valve adopts suitable materials to meet the requirements of low, medium and high medium temperature and corrosive medium

The failure rate of Electric Butterfly Damper Valve is very low. It's very convenient to use. And because its sealing system is metal sealing, so the service life is longer than elastic seal, and has the characteristics of high temperature resistance. And Electric Butterfly Damper Valve can also be customized according to the needs of customers

1. Exhaust Gas Smoke Louver Ventilation Butterfly Valve is made of high quality material, which can be well resistant to corrosion, high temperature, oil and acid

2. The surface of Exhaust Gas Smoke Louver Ventilation Butterfly Valve is beautiful and flat, and the professional production process improves the stable performance of the product. It is solid, compact and has a long service life

3. We can customize various specifications according to customers' requirements, and we will provide you with solutions

There are no connecting rod, bolt and other components in its interior, so some component problems will not occur in the use process, so the failure rate is very low. It's very convenient to use. It is a reliable valve device.

Because there is a large gap between the butterfly plate and the valve body of Stainless Steel Damper Control 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.

Because of the wide selection of materials, this kind of ventilation butterfly valve also has the characteristics of high temperature resistance, there will be no friction when opening and closing, and the service life is extremely long.

The main body of the valve is welded structure. The Electric Louver Butterfly Valve disc is composed of several shutter discs 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

Large Diameter Big Size DN4600 Damper Butterfly Valve is welded with high-quality wear-resistant materials, with good wear resistance, stable and reliable operation, easy operation, sensitive action, small leakage rate, long service life and convenient installation and maintenance. It is especially suitable for low pressure difference, large diameter and large flow occasions. It is used in combination with various actuators to form different performance valves.

1. The material of the product is strictly selected, controlled and selected strictly
2. A variety of production equipment in the factory can receive a large number of orders and supply in time
3. Mature production technology, fast delivery

In addition to the advantages of general butterfly valve, Ventilation Volume Control Damper has a unique structure. It is welded with high-quality steel plate. Ventilation Volume Control Damper has small volume, light weight, large flow section, flexible opening and closing, convenient use and maintenance, and low price. Ventilation Volume Control Damper can be wafer connection or flange connection.
