Installation position of the solenoid valve on the control valve

Thread Content

Why do the specifications for safety instrumentation in the petrochemical industry require that solenoids on control valves be installed between the valve positioner and the actuator? Solve!

Cut off the air supply to the control valve, and at the same time release the instrument air inside the control valve.

Will it work if it’s not installed between these two?
