QR1C Quick Release Valve

The Automann 170.289714 QR1C Quick Release Valve is engineered for speed and reliability in heavy duty pneumatic brake systems. As a QR1C valve, it vents service air quickly at the valve itself, reducing lag in brake release time and improving driver control response. It features a built-in double check valve to isolate sources in split system designs. The supply and balance ports are 1/4″ NPT, and the delivery port is 3/8″ NPT. Cross-referenced to major OEMs such as Bendix, Mack, IHC, Velvac and more, it offers drop-in replacement potential. Wofford Truck Parts supports this unit with quality assurance, fast shipping, and a commitment to compatibility. Whether installed on a tractor or trailer, this valve helps reduce response delays, preserve system integrity, and simplify parts inventory.
