The Wabco Double Check Valve, part number 9340990250, is a genuine Wabco brake system component for heavy-duty truck applications. Double check valves are used in air brake circuits to allow two independent air signals to share a single downstream line while preventing back-flow between the two supply sources. This design is standard in systems where two control circuits must feed one actuator or relay valve. Pro Gear and Transmission carries this Wabco part for fleet and shop buyers who need an exact OEM replacement. Call us to confirm this valve suits your specific air brake circuit before ordering.
