How to adjust the PRD parameters of control valves
Thread Content
During operation, in order to ensure the stable functioning of the instruments, it is generally necessary to adjust the PRD parameters. How should you go about adjusting them?

PID stands for Proportional-Integral-Derivative control. You can search for it on Baidu; there are some mnemonics for adjusting it, but in practice one needs to have a good understanding of the operating conditions and conduct repeated tests to find the optimal values
