Because the butterfly valve relative to the gate valve, the ball valve pressure loss is relatively large, so suitable for the pressure loss requirements of the pipeline system is not strict; Butterfly valve can be used as flow regulation, so in the need for flow regulation in the pipeline is suitable for selection.
Due to the structure and sealing material of butterfly valve, it is not suitable for high temperature and high pressure environment. General working temperature is below 300 degrees Celsius, working pressure is below 40 kilograms. Butterfly valve structure length is short, and can be made into a large diameter, so suitable for the valve structure length requirements short or large diameter valve occasions.
