Here we look at, how functional test is done for solenoid valve using instrument air.
Solenoid Valve Testing:
· Air supply is connected to the Air Filter Regulator (AFR).
· Set the stress required in the AFR and link the AFR outlet to the Solenoid valve.
· Connect outlet of Solenoid Valve to a Ball valve.
· Connect a pressure gauge at the Solenoid Valve outlet.
· The aim of Test Gauge is to verify the inlet line stress depends on SOV energy.
· Ball valve used to stop the functional testing
Typical Solenoid valve Test Set-up:
· Check the nameplate for the manufacturer/instrument datasheet. Confirm the voltage / current scores of the solenoid valve (consider + 24V DC device in our instance)
· Check the solenoid valve port configuration.
· Hook-up tool according to the typical sample configuration.
· Apply air-specified valve port stress and link 24VDC to valve terminals with solenoid.
· Switch on the 24VDC energy supply, inspect the energy valve by controlling the stress of the sample gage (increasing pressure).
· Turn off the supply. Confirm the de energized valve, inspect the value of the sample gage again (Diminishing stress)
· Tabulate all result in Check Sheet.
