Configuring Valves

The valves in the Valve Oven are gas-actuated. The valves are controlled by
solenoid valves that are turned on and off by timed events. Each solenoid valve
uses one timed event. Valve 1 will use timed event # 8, Valve 2 will use timed
event # 7, and so on. Once a valve occupies a timed event, this timed event is
removed from the list of external events that can be added to a run table.

You can configure a valve to be a gas sampling valve or a switching valve.

Gas Sampling Valves

Gas sampling valves have two positions—Load and Inject. These correspond to
the OFF and ON positions, respectively. Gas sampling valves are plumbed so that
counter-clockwise position is Load and the clockwise position is Inject

Figure 2-7. Mechanical Stop Positions for Gas Valves

Switching Valves

Switching valves have two positions—On and Off. Switching valves are plumbed
so that the counter-clockwise position is Off and the clockwise position is On.

NOTE

Typically, the valve nearest to the rear of the Valve Oven will be configured as valve 1.
