Tips: What is Wafer Type Butterfly Valve?
The wafer type butterfly valve controls opening and closing through a disc reciprocating 90 degree rotation in order to regulate the flow of media in the pipeline. The wafer style butterfly valve has many advantages, such as light weight, small installation size and easy to operate among other things, which is one of the fastest developing valves in recent decades. Butterfly valves are widely used. Its reliability and other performance indexes have reached a high level. With the application of chemical-resistant synthetic rubber on butterfly valves, the performance of butterfly valves can be improved. Butterfly valves have low flow resistance when fully open. When the disc is opened in about 15° - 70°, and it can be sensitive for flow control, thus in the field of large-diameter regulation, butterfly valve is a very common application. Most butterfly valves can be used in media with suspended solid particles because the disc movement is scrubbing. Depending on the strength of the seal, it can also be used for powder and granular media. Butterfly valves are designed for flow regulation. Butterfly valve in the pipe pressure loss is relatively large, about three times as much as a gate valve. So when choosing a butterfly valve, the pipeline system impact of the pressure loss should be fully considered. In addition, consideration must be given to operating temperature limitations of resilient seat materials at high temperatures. The structure length and overall height of the butterfly valve is smaller, opening and closing speed is faster, so it has good fluid control performance. Butterfly valve structure is most suitable for the manufacture of large diameter valves. When butterfly valves are required for flow control, the most important thing is to correctly select the specifications and types of butterfly valves so that they can work properly and effectively.
