MORE INFORMATION

TECH TIP

The rotor material in these valves sometimes develops a tendency to stick, making the valve difficult to turn. (This usually occurs at lower temperatures.) In extreme cases, the valve doesn't position accurately, and the valve and rotor can be damaged. Technical Note 201 contains instructions for reconditioning the material if this condition should arise.

STANDOFFS

GC valves usually require a standoff - an extension between the valve and actuator which allows the valve to be mounted in the heated zone while the actuator or handle remains outside at ambient temperature.
