Solenoid Valves, Continued
Operation Test
Step Procedure
1. Using a fine pointed object, depress orange button on the
solenoid.
2. When depressed, pressure is applied to the piston that moves
to either the open or closed position. Resulting pressure is then
applied to the column or sample valve.
3. If piston does not operate when the button is depressed, check
for correct gas pressure.
4. If piston does not operate and pressure is 75 psig, Solenoid
Valve is defective and must be replaced.
5. Repeat for each valve operating on and off. Allow at least 1
second between depressions.
The following specifications are applicable to the Solenoid Valves.
