Step 11. Attaching valve actuator air
Valves require air to actuate. Valves should have a dedicated air source; they
cannot share detector air supplies.
Valve actuator air is supplied through 1/4-inch plastic tubing. If your GC has
valves, the plastic tubing will already be attached to the actuators and will extend
from the back of the GC.
Caution Route the tubing away from the oven exhaust. The hot air will melt the plastic
tubing.
Materials needed:
❐ 1/4-inch SWAGELOK fittings and front and back ferrule
❐ Two 9/16-inch wrenches
Turn the air off at the source. Use a sharp knife if you need to shorten the tubing.
Connect the tubing to the air source using a 1/4-inch
SWAGELOK nut. See
Figure 19.
