Do you really understand the use of butterfly valves

Butterfly valve is suitable for flow regulation. Because the butterfly valve in the pipeline pressure loss is relatively large, about three times the gate valve, so in the selection of butterfly valve, should fully consider the pipeline system affected by the pressure loss, should also consider the closure of the butterfly plate under the pipeline medium pressure robustness. In addition, the limitations of the operating temperature that the elastic seat material can withstand at high temperatures must be considered.

The structure length and overall height of the butterfly valve is small, the opening and closing speed is fast, and has good fluid control characteristics, the structure principle of the butterfly valve is suitable for making large diameter valves. When the butterfly valve is required to be used for flow control, it is important to correctly select the size and type of the butterfly valve, so that it can work properly and effectively.

The selection principle of butterfly valve:

1. Because the pressure loss of butterfly valve is larger than that of gate valve and ball valve, it is suitable for the pipeline system with less strict pressure loss requirements.

2. Because the butterfly valve can be used for flow regulation, it is suitable for selection in the pipeline that needs flow regulation.

3. Due to the structure and sealing material of the butterfly valve, it is not suitable for high temperature and high pressure pipeline system.

4 Because the structure length of the butterfly valve is short, and can be made into a large mouth, so in the structure length requirements of short occasions or large mouth valve, should choose butterfly valve.

5. Because the butterfly valve can be opened or closed only by rotating 90°, it is appropriate to choose the butterfly valve when the opening and closing requirements are fast.
