XAAD`s are pressure fed air atomising nozzles, you`ll need to supply them with compressed air and liquid under pressure via seperate solenoids.
You`ll be hard pushed to find an adjustable pressure valve to cover that range. Is it for pressure relief purposes (accumulator tank safety) or perhaps pressure reduction to control the liquid pressure to the nozzle(s)? If its the latter then a valve wont do it,
