A WABCO Air Brake Emergency Relay Valve becomes essential when a sudden loss of supply air pressure could otherwise delay emergency brake application. Whether caused by a trailer disconnect or a ruptured air line, pressure loss requires an immediate response to help maintain vehicle control. Designed to sense these conditions automatically, the WABCO 4710030200 applies the brakes using air stored in the vehicle's emergency reservoir. Automatic emergency actuation helps provide braking capability even when the primary supply circuit is no longer available.
