Chalwyn Valve UK

Agriemach supply Chalwyn Air Intake Shutdown Valves throughout the UK and Europe, engineering the inlet and outlet to the specific inside diameter of the air intake hose.

Air intake shutdown valves (often referred to as AISV, ASOV or Emergency Shutdown valves, ESD) and systems provide emergency overspeed shutdown protection for diesel engines and 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.

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 re-starting.

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 combination of the engine power at its rated speed and the air intake line bore size.

Features and Benefits

• Easy to install
• No external power source or speed signal required
• Air flow actuated
• Automatic reset after engine stops
• Option for remote pull "T" handle close
• Trip setpoint calibrated on engine

 

The Chalwyn DF and DF-AM automatic valves with integral air filters 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 re-starting.

The DF automatic valve includes an integral air filter mounted directly on the intake of the valve to reduce the size and complexity of installing the valve into engine packages where space is limited. This eliminates the requirement to find a location to support and mount a separate air filter and the associated air intake line upstream of the valve.

The Model DF is an automatic valve with automatic reset. The DF-AM adds a manually actuated pull “T” handle cable stop. The cable is available in lengths 0f 1.0, 1.5, 2.0, and 3.0 meters.

The valves are available in two size ranges and are selected by combination of the Air Intake Line bore size and the engine power at its rated speed.

Features and Benefits

• Easy to install
• Integral air filter for compact engine packages
• No external power source or speed signal required
• Air flow actuated
• Automatic reset after engine stops
• Option for remote pull "T" handle close
• Trip setpoint calibrated on engine
