Chalwyn D Automatic Air Shut Off Valve
The Chalwyn D and D-AM automatic valves are self-contained with flow actuated overspeed shutdown. They require no external electrical or mechanical input devices. The closing force is provided by the intake air flow passing through the valve. The valve closes automatically when the engine speed exceeds a pre-set point. The valve automatically resets open soon after the engine has stopped, so the engine is ready for restarting.
The Model D is the basic version of the automatic valve. The D-AM is the automatic valve with a manually operated pull âTâ handle cable stop. The cable is available in lengths of 1.0, 1.5, 2.0, and 3.0 meters. The valves are available in 3 size ranges and are selected by combination of the engine power at its rated speed and the air intake line bore size.
