Enhances overspeed protection
Wyndham Page, the diesel engine protection equipment manufacturer, has launched a range of cost-competitive shutdown valves for diesel engine overspeed protection in areas in which hazardous concentrations of flammable gas or vapours may exist.
The V series mechanical action valves use a new concept design which automatically closes the air intake once a pre-set engine speed is exceeded.
Suitable for both normally aspirated and turbocharged diesel engines up to 275 kW (370 HP), these compact valves are said to improve on the well-established differential pressure intake airflow principle for automatic shutdown. They also incorporate a manual emergency shutdown feature to meet the requirements specified in EN 1834-1:2000 for diesel engine air intake shutdown valves for operation in hazardous areas.
Furthermore, the valve has been designed to necessitate a manual reset with positive intervention by an operator rather than rely upon potentially outmoded and less safe practice where the valve automatically resets on an engine restart.
