Who specify control valve accessories?

I am reviewing purchasing package of a bulk buy of control valve in one oil and gas company.

I noticed that some control valve consists of solenoid valve, switches, boosters etc while some other not.

i am wondering for these major oil and gas company, when they do a bulk buy of control valves to suit several tag locations, who (End client's spedification? major designer of the plant? Control valve vendor?) is responsible and at what stage to specify which control valve accessories that is required?

Or if i ask my question from another angle: how do the control valve vendors (fisher / flowserve / masoneilan) know they need to include a solenoid valve or switches into an assembly and how do they know what specification is suitable for these accessories?

Thanks.
