Ensure reliable and safe braking performance in your Vol truck, bus, or construction vehicle with this high-quality air brake control valve, designed as a direct-fit replacement for OEM part numbers:
Commonly referred to as an air brake relay valve, dual circuit protection valve, or brake modulating valve, this critical component plays a vital role in the pneumatic braking system by regulating air pressure distribution between the front and rear axles, ensuring balanced braking force and fail-safe operation in case of partial system failure.
Engineered for durability and precision response, this valve is built to meet or exceed Vol’s stringent performance standards—ideal for heavy-duty applications in long-haul transport, regional freight, mining, and municipal fleets.
