Semi-Truck Tractor Protection Valves

Tractor Protection Valves are vital for maintaining the safety and integrity of tractor-trailer air brake systems. Their primary function is to protect the tractor’s air supply in the event of trailer separation or major air loss by automatically shutting off airflow to the trailer. These valves also control the trailer air supply valve in the cab and help prevent unintended spring brake application during normal operation.

At MaxiTrucks, we offer a selection of reliable, heavy-duty Tractor Protection Valves engineered to meet or exceed DOT safety regulations. Built with corrosion-resistant materials and tested for high-pressure performance, each valve ensures consistent operation and peace of mind for fleet operators, owner-operators, and technicians alike.
