Brake Valve

Genuine OEM Brake Valves

A leaking or malfunctioning brake valve can cause uneven air pressure distribution, delayed brake response, or a complete loss of braking on part of the system. Because brake valves regulate and direct compressed air throughout the air brake circuit — from the foot valve to relay valves and quick-release valves — a wrong or generic replacement often can't maintain the precise pressure thresholds the system requires. That's why every brake valve in this collection is genuine OEM, matched to the manufacturer's original part number.

What's in this category

This collection covers genuine OEM brake valves for heavy-duty trucks and equipment, including foot valves, relay valves, quick-release valves, and other air brake circuit components engineered to regulate pressure and airflow within the manufacturer's original brake system specifications. New listings are added regularly as inventory expands.

FAQ

What does a brake valve do? It regulates and directs compressed air through the brake system, controlling when and how much pressure reaches the brake chambers on each axle. Different valve types handle different functions — from initial driver input (foot valve) to pressure relay and quick release.

Signs of a failing brake valve? Air leaks from the valve body, slow or uneven brake application, brakes that won't fully release, inconsistent brake pedal feel, or low air pressure on one circuit of the system.

Genuine OEM or aftermarket? All parts here are genuine OEM — no generic substitutes.

How do I find the right brake valve? Match the OEM number on your old valve, or check your service manual for the correct valve type and system configuration, then search that number above.
