Description

The heavy-duty Unloader Valve is a critical component within the pneumatic brake system, ensuring precise pressure regulation and operational stability. Designed for high-strength performance, this part manages air-flow dynamics to maintain consistent system pressure during heavy-duty transport cycles.

301.01.0012 is the OE-equivalent of the WABCO 975 303 082 0 unloader valve used in DAF, LEYLAND, and RENAULT TRUCKS vehicles. This component ensures seamless integration with compatible braking systems and meets strict industrial standards for heavy commercial vehicle maintenance.

For workshop technicians, this unit features high-precision port specifications including Port 1 (M22x1,5) and Port 21 (M22x1,5). It is engineered to operate with a cut-out pressure of 9,8 BAR / 0,2 BAR. Proper installation and regular inspection of the recycle valve functionality are recommended to ensure long-term reliability within the pneumatic circuit.

Regular maintenance of the unloader valve helps prevent pressure fluctuations in the braking system. Technicians should verify the integrity of the M12x1,5 connection at Port 22 during routine service intervals to maintain optimal vehicle safety and system response.
