How are the opening and closing times of control valves determined? Under what conditions is it determined? Seeking advice, thank you!
The opening and closing times of self-control valves are determined based on the process requirements; when rapid opening or closing is required by the process, corresponding fast-opening or fast-closing valves are selected. The quick closing time of a valve is closely related to the selection of that valve; different models of valves have different structures, as well as different cylinders, springs, and accessories, all of which affect the valve’s quick closing time. Generally, the switching time for pneumatic on-off valves is less than 2 seconds, while electric on-off valves may take longer.
The rapid opening and closing of valves depend on effective process control
From the perspective of automatic control, it also measures the time required for the valve to reach its closed position. The specific requirements are determined based on the process needs
