Following the introduction of the original and very successful CHALWYN D VALVE in 1972, the CHALWYN diesel engine safety product range now includes automatic overspeed air and fuel shut off valves, air pressure, oil pressure, manual and electrically operated air intake shutoff valves, flameproof alternators, exhaust spark arrestors and complete engine monitoring and automatic shut down systems.
In 2008 Chalwyn was acquired by AMOT. Together, the AMOT, Roda Deaco and Chalwyn brands offer an extensive family of engine safety solutions.
