Valve selection in control systems

In general control systems, depending on the properties of the fluid and the required control precision, self-acting ball valves, butterfly valves, single-seat control valves, cage-type control valves, etc., are typically chosen. Our factory uses a large number of ball valves, which meet the requirements in terms of pressure resistance and reliability. However, compared to butterfly valves and the like, ball valves are considerably more expensive. Currently, we are planning to launch new projects. Since solenoid valves are not used very frequently, we would like to ask our colleagues: under what conditions can solenoid valves be used as a substitute for two-position ball valves (electric or pneumatic)? What are the advantages and disadvantages? Please give some guidance.
