Intake Air Shut-off Valve Model 4261M Overview Diesel run-away is a potential problem that can cause damage to equipment. A diesel engine can run away and self destruct on hydrocarbon vapors, even if the engine’s primary source of fuel is taken away. An air intake shut-off valve is recommended for diesel engines which have a possibility of encountering hydrocarbon vapors. 4261M Intake Air Shut-off Valve Typical applications Operation l Oil field - drilling rigs, mud trucks, wireline The 4261M Intake Air Shut-off Valves from AMOT feeders, crude haulers, welders and other use the best available technology to shut down a machinery run-away diesel by positively choking off engine intake air. They are 2.8, 3.5, 5.5 and 8.0 inch l On/off shore - compressors, gen sets, fire diameter, remotely operated butterfly valves pumps and welders designed to be installed in the engine intake. l Construction - ideal for trenchers, gas co When a condition is detected that could damage service trucks, sewage pumpers the engine (over temperature, over speed), the valve trips shut, closes off the air intake and l Transporters - aircraft refuelers and all stops the engine to prevent serious damage. combustable chemicals or hazardous waste Figure 1 illustrates a typical installation of a
