Positive Air Shutoff Valve

Model RB2A Compact Butterfly Valve

Overview

The Roda Deaco RB2A range is a compact butterfly design air intake shutoff valve available with electrical or mechanical actuation. Actuation of the RB2A solenoid rapidly closes the valve’s sealing element which shuts off intake air flow into the engine.

The RB2A can be used in fully automatic or manual shutdown systems. When incorporating into an automatic overspeed shutdown system, this valve is compatible with the Revguard 2 Speed Switch.
