Diesel engine safety products

CHALWYN are leading manufacturers of safety products for diesel engines which are required to operate either in hazardous areas where combustible gas, vapours or dust may exist, or in situations demanding special safety precautions.

Following the introduction of the original and very successful CHALWYN D VALVE in 1972, the CHALWYN diesel engine safety product range now includes automatic over speed air and fuel shut off valves, air pressure, oil pressure, manual and electrically operated air intake shut down (shut off) valves, flameproof alternators, exhaust spark arrestors and complete engine monitoring and automatic shut down systems.
