Can the pneumatic ventilation square butterfly valve automatically reset on HVAC? Before installation and assembly of pneumatic butterfly valve, people need to understand the structure and characteristics of the valve. The structure of this new butterfly valve is not very complex. The size data is relatively small, the load capacity is strong, and it will not consume too much material. The size of the assembly is also relatively small. The opening and closing are very fast, and it can achieve 90 degrees of repeated rotation, and the driving torque is small. Its main function is to cut off, connect and adjust the flow medium in the pipeline.
、 The electrical positioning component mainly compares the supply value of the component position with the actual value. This comparison operation will be carried out in the micro processing component. The micro processing component will output an electric control command to the piezoelectric component according to the deviation of the control limit. The piezoelectric component will convert this command into aerodynamic force to determine the number of position increases. If the control limit values are very different, Then the piezoelectric components will transmit continuous signals. If the difference between the control limit values is small, then the fixed pulse transmission will not be carried out on the pneumatic butterfly valve,
