Supplying valve actuator air
Some valves use pressurized air for actuation (others are electrically or manually
driven). Actuator air must be free of oil, moisture, and particulates. It can be
supplied from a dried regulated cylinder, although “house” air supplies or air
from a compressor are acceptable.
Most valves require 20 to 40 psi of pressure to operate. High-pressure valves may
require 65 to 70 psi.
Valves require a dedicated air supply. Do not share valve air supplies with
detectors.
See Chapter 9, “Valve Control,” in the Agilent 6890 GC Operating Manual,
Volume 1 for more valve requirements.
