Air intake shut off valves 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. AMOT has an extensive range of fully automatic and manual positive air shut off systems (PASS) designed to fit engines of all sizes. Our products include AMOT, Chalwyn, Rigsaver and Roda Deaco brands.
