FSX-200 Air Intake Shut Off Valve

The AMOT FSX-200 air intake shut off valve is designed to be used in combination with Chalwyn by AMOT Butterfly or Self-Contained Automatic Air Intake Shutoff Valves. The AMOT FSX-200 will automatically close down the engine diesel fuel supply when the Air Intake Shutoff Valve closes due to an engine overspeed condition. The FSX-200 also incorporates a manual shut down push button.

The FSX-200 air intake shut off valve also meets the European standard EN 1834-1:2000, covering diesel engine operation in zone 1 or zone 2 hazardous areas where flammable gas or vapour may exist. This standard requires that both the engine fuel and intake air supply are automatically shut down if engine overspeed occurs.

How to use

First start. Once the engine is running, trip the air intake shut down valve. The engine should immediately stop, and the stop button on the FSX-200 should automatically retract to the stop position. Once the engine has stopped, the FSX-200 may be reset by pulling out the stop button or, alternatively, if left for a few minutes to permit any differential fuel pressure across the fuel valve to fully decay, the FSX-200 will generally automatically reset itself.

Note: if the stop button on the FSX-200 is manually operated to stop the engine, there may be a delay in action whilst any residual fuel between the FSX-200 and engine is used.
