WABCO Air Brake Solenoid Valve 4721706060 24V Normally Closed Control for Commercial Truck Brake System

The WABCO WABCO Solenoid Valve (part number 4721706060) 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 13 bar, temperature range -40°C ~ +80°C, Port Thread M12*1.5, rated current 690mA, Protection Class IP6K6 /.

Precision machined internals and sealed electrical connections keep the valve responsive across the full operating temperature range, so braking stays predictable from a cold winter start to a long summer descent. Every unit is tested before packing and mirrors the fit, function and durability of the original equipment part, which makes replacement quick and keeps fleets on the road.

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.

• Max Working pressure:13 Bar: Temperature range -40°C ~ +80°C.
• Port Thread: M12*1.5: Rated current 690mA.
• Protection Class IP6K6 / IP6K9K: Excellent waterproof and dustproof performance.
• Fast Response: Precisely controls air circuit for traction control system, prevents drive wheel slipping.
• OE Original Quality: Stable under strong vibration and extreme temperature, easy installation.

The valve is used on the air-brake and air-suspension circuits of heavy trucks, semi-trailers and buses, including long-haul tractors, tippers, tankers and container chassis. It suits fleets that operate in mixed conditions, from dry highways to wet, dusty and freezing environments, where a reliable, quick-acting solenoid valve is essential to safe braking and stable suspension control.

Every unit is packed in a neutral export carton with foam protection so that ports, connectors and levers arrive free from damage. OEM cartons and private labels are available on request, and each carton is labelled with the part number for simple warehouse handling. All units are produced to original equipment specification and inspected before shipment; a twelve-month quality warranty and full technical support are provided, and mixed containers can be supplied for distributors and repair workshops.
