Description and Purpose

The D-2 Commercial Truck Air Governor Valve is a crucial component in the air brake system, designed to regulate air pressuree within a truck’s air compresor. This valve maintains optimal brake system functionality by controlling when the compressor engages and disengages, ensuring consistent air supply to the braking system.

Why Replacement is Important

A malfunctioning governor valve can lead to excessive air pressure buildup or insufficient air supply, resulting in brake system inefficiencies or failures. Replacing a worn or defective valve ensures the air brake system operates within the recommended pressure range, reducing the risk of brake malfunction and improving vehicle safety.

Impact on Vehicle Performance

By maintaining the correct air pressure, this valve contributes to smooth braking performance and extends the liffespan of the air compressor. Its adjustable pressure range (110-130 PSI) allows for precise regulation, preventing over-compression and reducing strain on the air system. With a durable design capable of withstanding extreme temperatures (-40°F to 200°F), this valve ensures reliable braking performance in various driving conditions.
