26A81X-0107 Valve Quick Release, (1) 1/2 P.T (2) 1/4 P.T QR-1 RKN32011

It speeds up brake release by exhausting air locally at the valve instead of sending it back through longer lines. This helps reduce brake drag and improves response time in an air brake quick release valve application. It’s commonly used where faster release is needed at the service brake chambers.

It uses one 1/2" P.T. port valve connection as the supply port and two 1/4" P.T. port valve connections as delivery ports. Use the proper NPT/P.T. thread sealant and avoid over-tightening to prevent thread damage or leaks. If you’re replacing a QR-1 quick release valve or RKN32011 valve, match the line routing and port function before pressurizing.

Yes, it’s commonly used as a replacement where QR-1 quick release valve and RKN32011 valve fitment is specified, provided the port sizes and plumbing functions match. Confirm the mounting orientation, supply/delivery port arrangement, and any system requirements before installation. After installation, perform a leak check and verify proper apply/release behavior under normal operating pressure.
