CBF-500 light air duct butterfly valve with plug-in plate valve

A completely new level.

When the butterfly valve is opened, it has a small flow resistance. When opened between approximately 15 °~70 °, it can also perform sensitive flow control, so butterfly valves are widely used in the field of large-diameter regulation.

Due to the wiping nature of the butterfly valve disc movement, most butterfly valves can be used for media with suspended solid particles. Depending on the strength of the seal, it can also be used for powder and granular media.

CBF-500 light air duct butterfly valve with plug-in plate valveButterfly valves are suitable for flow regulation. Due to the significant pressure loss of butterfly valves in pipelines, which is about three times that of gate valves, when selecting butterfly valves, the impact of pressure loss on the pipeline system should be fully considered, as well as the strength of the butterfly plate to withstand the pressure of the pipeline medium when closed. In addition, it is necessary to consider the limitations of the working temperature that the elastic valve seat material can withstand at high temperatures.

The structure length and overall height of butterfly valves are relatively small, with fast opening and closing speeds and good fluid control characteristics. The structural principle of butterfly valves is based on the production of large-diameter valves. When butterfly valves are required for controlling flow,What is needed is to choose the correct specifications and types of butterfly valves so that they can work properly and effectively.

Usually, in throttling, regulating control, and mud media, it is required to have a short structural length, fast opening and closing speed, and low pressure cutoff (small pressure difference), and butterfly valves should be selected. Butterfly valves can be used for channels with dual position adjustment, reduced diameter, low noise, air pockets and vaporization, small leakage to the atmosphere, and abrasive media. Under special operating conditions such as throttling regulation, strict sealing, severe wear, and low temperature (cryogenic) requirements.
