The Spanish double shaft soft seat manufacturer tells you that the butterfly valve has a small flow resistance when it is fully opened. When the opening is between about 15°~70°, it can also perform sensitive flow control, so in the field of large-diameter regulation, the application of butterfly valves is very common.

Since the movement of the butterfly plate is wiping, 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 powdery and granular media.
Butterfly valves are suitable for flow regulation. Since the pressure loss of the butterfly valve in the pipe is relatively large, about three times that of the gate valve, when selecting a butterfly valve, the influence of the pressure loss on the pipeline system should be fully considered, and the strength of the butterfly plate to withstand the pressure of the pipeline medium when it is closed should also be considered. . In addition, the limitation of the operating temperature of the elastic seat material at high temperature must also be considered.
The Spanish double shaft soft seat manufacturer tells you that the butterfly valve has a small structural length and overall height, fast opening and closing speed, and good fluid control characteristics. The structural principle of the butterfly valve is most suitable for making large-diameter valves. When the butterfly valve is required to be used for flow control, the most important thing is to correctly select the specification and type of the butterfly valve so that it can work properly and effectively.
Generally, butterfly valves are recommended for throttling, regulating control and mud media where short structural length, fast opening and closing speed, and low pressure cut-off (small pressure difference) are required. The manufacturer of the Spanish double shaft soft seat tells you that butterfly valves can be selected for double-position adjustment, reduced-diameter channels, low noise, cavitation and vaporization, a small amount of leakage to the atmosphere, and abrasive media. Throttle adjustment under special working conditions, or working conditions that require strict sealing, severe wear, low temperature (cryogenic) and so on.
