Various faults may occur in the daily use of the regulating valve. Here is an introduction to the common faults. Solution for poor stability of control valve: change the action direction of unbalanced force method: in stability analysis, when the action of known unbalanced force is the same as the valve closing direction, that is, when the valve has a closing trend, the valve stability is poor. When the valve works under the above unbalanced force conditions, the method of changing its action direction is usually to change the flow closed type to the flow open type, which can easily solve the stability problem of the valve.

Of course, if it is purchased, if it is within the maintenance period, it can be directly sent back to the company, and we will give you a satisfactory answer. Therefore, the equipment supervision engineer summarized the fault from the actuator in the electric three-way ball valve:
