7000 Series Swing Gate Valve Product Page
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.
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 the Air Intake Shutoff Valve into a diesel engine air intake line. The kits are designed to meet specific engine model and application requirements.
