The WABCO WABCO Trailer Control Valve (part number 9730090020) is a replacement component for the air brake and air suspension systems of heavy-duty trucks, buses and semi-trailers. It is built to original equipment specification from quality materials, so it installs on the original mounting points and performs reliably throughout the service life of the vehicle. Key ratings include Max Working Pressure 8.5 bar, temperature range -40°C ~ +80°C, Port Thread M22*1.5 for main ports, M16*1.5 control port, Mounting 4*M8 bolts, mounting hole spacing 85*85 mm, dimension 193*144*139 mm.
By metering the air that reaches the trailer brake chambers, the valve synchronizes trailer braking with the tractor and removes the dangerous lag that can otherwise cause a jack-knife. Stable pressure output and a robust body keep performance consistent over years of heavy-duty service.
Every unit is manufactured to original equipment specification and inspected before it leaves the factory, so it matches the fit, function and durability of the original part. Sealed, vibration-tested construction keeps performance stable in the heat, dust, road salt and constant vibration found on commercial vehicles, and standard interfaces make installation and maintenance straightforward. Spare parts, technical data and fitting advice are available on request.
