How to connect the 8 wires in the internal wiring diagram of pneumatic light butterfly valve actuator? The commonly used butterfly valves are wafer type butterfly valve and flange type butterfly valve. Wafer type butterfly valve uses stud bolts to connect the valve between two pipe flanges. Flange type butterfly valve has flanges on the valve, and bolts are used to connect the flanges on both ends of the valve to the pipe flanges.
、 First, pressure drop If the pressure of pneumatic butterfly valve is very high, it will increase energy consumption. But you need to know that this valve is not the only factor that causes pressure drop in the pipeline system. In fact, there are other factors that cause pressure drop. The change of the flow direction of the fluid section of the pipe, the friction force of the inner wall of the pipe, etc. when passing through the parts. The fluid characteristics of butterfly valves are three times higher than those of globe valves, which is equivalent to 75% of gate valves of the same size.
