Semi-Truck Trailer Valves

Trailer Valves are essential components in heavy-duty air brake systems, specifically engineered to control service and emergency brake functions on trailers. These valves regulate the air flow between the tractor and trailer, ensuring synchronized braking performance and rapid response under all driving conditions. Common types include trailer control valves, service valves, emergency valves, and relay emergency valves, all designed to meet DOT and industry standards.

At MaxiTrucks, we offer a wide range of Trailer Valves compatible with popular tractor-trailer setups. Each valve is built with high-grade materials, corrosion-resistant finishes, and precision-engineered internals for long-lasting durability and consistent performance — even in harsh road environments.
