Malfunction Analysis of Type 403 Pneumatic Proportional Integral Regulator

By taking type 403 pneumatic proportional integral regulator as an example, the structure and working principle of instruments in this category were analyzed.The common faults and the way of treatment were also discussed.If the action mode of the regulator is correctly selected according to the need of work field and the proportional integral parameters are reasonably adjusted, the regulator will work perfectly.
