What are the adjustment methods for pneumatic butterfly valves
The adjustment of pneumatic butterfly valves should be based on their performance
1. If it is a switch type pneumatic butterfly valve, it is only necessary to adjust the valve plate of the butterfly valve to the correct position before installing the pneumatic actuator, and wait for the installation of the pneumatic actuator limit switch and solenoid valve to be completed before conducting a gas source test on the switch effect.
2. If the pneumatic butterfly valve is a regulating type, it needs to be set to the corresponding angle in combination with the analog signal of the electric control cabinet.
3. If the pneumatic butterfly valve is an intelligent type, it is necessary to add a PLC part and program it in conjunction with the electrical control cabinet signal to visualize the results
