DESCRIPTION:
Model: Quick Release Valve (QR-1 Style)
Vehicles: Compatible with all heavy-duty trucks, trailers, and buses using air brake systems
• Valve Type: Quick release
• Function: Rapidly exhausts air from service brake chambers, shortening brake release time; routes exhaust through valve rather than brake control valve
• Supply Port: 1 × 3/8" NPT
• Delivery Ports: 2 × 1/4" NPT
• Exhaust Port: Single integral vent (with silencer optional)
• Crack Pressure: 1 PSI standard (some listings cite 0 PSI differential)
• Actuation: Air-operated; non-graduating
• Mounting: Standard 2-bolt QR valve mount
• Mount Hole Dia.: 0.34" (5/16-18 UNC-3B implied)
• Center-to-Center Mounting: 1.5"
• Thread Type: NPT (National Pipe Taper)
• Body Material: Die-cast aluminum
• Dimensions: Approx. 10" × 8" × 4" (shipping size)
• Weight: Approx. 0.65 lbs
• Performance/Technology: Maintains 0 PSI differential during apply/release; noise-reducing optional; optimized for fast response and brake release
• System Integrity: Direct replacement for QR-1 valves in standard heavy-duty brake configurations
Applications:
Designed to improve air brake release times in heavy-duty vehicle systems by exhausting chamber air directly through the valve. Ideal for truck and trailer configurations where fast brake release and system efficiency are critical. Common in freight, bus, construction, and municipal fleet use.
