QR-1 Quick Release Valve Replace 229860 20QE2183R 1677539C91
Accelerates brake release by rapidly exhausting air from brake chambers directly through the valve body, reducing brake lag and improving response time. Installed inline near brake chambers in service brake circuits to minimize the distance air must travel during release, enhancing brake modulation and driver control. Aluminum construction provides durability while resisting corrosion in harsh road environments.
