RDS3 Swing Gate Valve (3” to 4½” | 76 to 114mm)



If flammable gas or vapor is present in the atmosphere surrounding a diesel engine, it can be ingested into the engine and become an ungoverned fuel supply. This ungoverned fuel can result in runaway engine overspeed, potentially leading to dangerous mechanical failure or an explosion.

The Roda Deaco RDS3 Swing Gate Valve is a compact air intake shutoff valve that provides emergency overspeed shutdown of a diesel engine. The RDS3 Swing Gate Valve can be triggered to close, which starves the engine of air and shuts down the engine.
