Roda Deaco positive air shutoff valves, speed switches, and accessories help shut down a diesel engine in the event of an overspeed. From compact to heavy duty, we have the right size and actuation method for your needs.
Our complete product line includes Roda Deaco, Chalwyn, Rigsaver and AMOT brands.
Ideal for applications with tight clearances. Examples may include, but are not limited to generators, skid steers, trucks and small dozers.
The Swing Gate Positive Air Shutoff Valve uses a "guillotine" method for emergency engine shutdown. It is offered in a variety of sizes and actuation methods.
A plug-n-play positive air shutoff system that uses the factory-installed throttle valve to immediately shut down the engine. Engine specific kits available for Ford, Dodge, and GM.
The Chalwyn brand D-AM automatic valves are self-contained with flow actuated overspeed shutdown. They require no external electrical or mechanical input devices.
The Roda Deaco Revguard Speed Switches detect the hazard of an overspeed condition. When engine RPMs exceed the Revguard’s program setpoint, the output is energized, providing the signal to actuate the air intake shutoff valve(s) to shut off your engine.
We have a wide range of Activation, Installation and Wiring Harness Kits to ease the installation of air intake shutoff valves. The kits are designed to meet specific engine model and application requirements.
