An autorelieving feature boosts travel and flow capacity from the proportional solenoid valve. The EBV uses a high-force solenoid, combined with a precision-fit spool and housing, in place of a pilot valve to maximize contaminant resistance and minimize leakage. The S12 uses a longer spool to incorporate a second flow path — which runs parallel to the standard path — for a higher flow capacity from brake to tank.
