Butterfly Valves Have Excellent Fluid Control Characteristics

Butterfly valves have a smaller flow resistance when fully open. When opened between approximately 15 ° to 70 °, it can also perform sensitive flow control, making butterfly valves 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. According to the strength of the sealing element, it can also be used for powdered and granular media.

Butterfly valves are suitable for flow regulation. Due to the significant pressure loss of butterfly valves in the pipeline, which is about three times that of gate valves, when selecting a butterfly valve, the impact of 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 closed should also be considered. 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 structural length and overall height of butterfly valves are small, with fast opening and closing speeds, and good fluid control characteristics. The structural principle of butterfly valves is most suitable for making large-diameter valves. When it is required to use butterfly valves for flow control, the most important thing 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, short structural length, fast opening and closing speed, and low pressure cutoff (small pressure difference) are required. It is recommended to use butterfly valves. Butterfly valves can be used for dual position adjustment, reduced diameter channels, low noise, cavitation and vaporization phenomena, small leakage into the atmosphere, and abrasive media. Under special operating conditions, throttle adjustment is required, or under conditions such as strict sealing, severe wear, and low temperature (deep cooling).
