Product Description
The WABCO 4721950320 is an ABS relay valve designed for heavy-duty trailer air brake and anti-lock braking systems. The valve combines pneumatic relay operation with ABS brake-pressure control to rapidly manage air pressure during normal braking and anti-lock events.
WABCO identifies the 4721950320 as an original-equipment-specification ABS relay valve. This older valve is associated with the later WABCO 4721950330 configuration and the Meritor R955378 / WABCO 4006120090 replacement family.
