Positive Air Shut Off Valve
Model RB2A, RB3A Compact Butterfly Valve
Overview
The Roda Deaco RB2A and RB3A are compact, butterfly-style air intake shutoff valves available with electrical or mechanical actuation. Actuation of the solenoid rapidly closes the valve’s sealing element which shuts off intake air flow into the engine. RB2A These models can be used in fully automatic or manual shutdown systems. When incorporating into an automatic overspeed shutdown system, these valves are compatible with the Revguard 2 Speed Switch.
