What is the leakage power of the pneumatic butterfly valve regulating valve? Pneumatic butterfly valves are used in industrial field, general service field, water treatment and HVAC and refrigeration industry. The pneumatic butterfly valve has two types of standard "on/off" control and "regulating" control. The pneumatic butterfly valve is simple in structure, small in size, light in weight, and only composed of a few parts. The valve can be quickly opened and closed only by rotating 90 °, which is simple to operate. At the same time, the valve has good fluid control characteristics. When the pneumatic butterfly valve is in the fully open position, the butterfly plate thickness is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has good flow control characteristics. To ensure the normal operation of the pneumatic butterfly valve, the inspection before installation of the pneumatic butterfly valve is essential.
、 The only resistance is the butterfly valve, because the pressure of some valves drops a lot. The pneumatic butterfly valve has two kinds of sealing discs, one is elastic, and the other is metallic.
