ventilation butterfly valve

1. The structure dimension is short, the weight is light, and the installation is convenient 2. Small driving torque, flexible opening and closing, convenient operation 3. There is no visible gap between the sealing pairs and the leakage rate is small 4. The expansion gap between butterfly disc and valve body is large, which can effectively prevent the jamming caused by heat expansion and cold contraction 5.The 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

The structure of the Ventilation Damper Butterfly Valve is welded by using the center line butterfly disc 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 ventilation butterfly valve device. 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. So it is widely used in building materials, electric power, metallurgy and other industries. In the temperature can be higher than 300 degrees in the medium pipeline, can be perfectly connected and closed regulation. Ventilation butterfly 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

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

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

The structure of Pneumatic Ventilation Butterfly Valve is welded by using the center line disc and short structure steel disc, 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. And because its sealing system adopts metal sealing, it has long service life and high temperature resistance. So it is widely used in building materials, electric power, metallurgy and other industries. Pneumatic Ventilation Butterfly Valve can also be customized according to the needs of customers.
