Introduction
NOTE Before starting, cool the Valve Oven to 50°C or cooler. Do not turn the GC off.
The heated section of the Valve Oven accepts standard Valco gas actuated valves
with 3-inch standoff. The unheated section will accommodate Valco gas actuated
valves without standoff.
CAUTION Be careful not to mix actuators with valves that have different numbers of ports, as
the actuator travel for each valve can be different.
Opening the Valve Oven
WARNING! The Valve Oven cover can be very hot. Use caution when removing the heated Valve
Oven cover.
1. Remove the top cover by releasing a single screw on the Valve Oven
compartment rear panel.
2. Slide the panel toward the rear about ½ inch and lift away. This exposes the
heated Valve Oven cover and valve pneumatics.
3. To remove the heated Valve Oven cover, locate the two thumb screws on the
lower edge of the heated Valve Oven cover.
4. Turn these screws counter clockwise (ccw) to release the cover. The cover can
be removed by lifting up and pulling out.
