Fuel Overboard Vent Connection
There is a fuel overboard vent port that must be vented to a safe location. In normal operation, this vent
should have very low leakage.
Never plug the fuel overboard vent port, which could cause the valve
to malfunction or to operate improperly.
Valve Characteristic Data
Flow testing is conducted on every valve before shipment. Results from this flow testing produce Cg
versus position characteristics of the valve. Each valve must demonstrate predetermined Cg
characteristics before it can be shipped.
Calibration
The actuator and controller perform an automatic rigging procedure. When the actuator controller is
activated, it performs an automatic rigging procedure that checks system health and verifies the value is
in the proper position. No additional steps are required from the operator.
