Chalwyn Air Intake Shutdown Valves
Agriemach offer a complete range of Air intake shutdown valves (often referred to as AISV, ASOV or Emergency Shutdown valves, ESD) and systems which provide emergency overspeed shutdown protection for diesel engines. They are the most effective way of preventing a runaway situation. The valves completely block the engine air intake system, cutting off an uncontrolled external fuel source and the air required to keep the engine running.
Our range includes Manual MVX Control Valves, Electric or Oil/Air Pressure-Auto or Manual Reset valves and Automatic Overspeed Chalwyn Valves. All valves are customised to fit in the air intake of each application and come complete with certificate of conformity.
Our popular Chalwyn D and D-AM automatic valves are self-contained with flow actuated overspeed shutdown. They require no external electrical or mechanical input devices which makes installation quick and easy. 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 re-starting. Adjustment of the preferred set point is carried out during installation – it is quick and simple to do, however there is always an Agriemach support engineer just a phone call away for peace of mind.
The Model D is the basic version of the automatic valve. The D-AM is the automatic valve with a manually operated pull “T” 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 a combination of the engine power at its rated speed and the air intake internal diameter.
