BD Diesel 1120121 Exhaust Brake Quick Release Valve

The BD Diesel 1120121 Quick Release Valve is an OEM-quality replacement component designed for use with BD Diesel air-actuated exhaust brake systems. The quick release valve plays a critical role in the exhaust brake's pneumatic circuit, rapidly venting air pressure from the actuating cylinder when the brake is released — ensuring fast, reliable brake disengagement and smooth drivability.

BD Diesel has been engineering exhaust brake solutions since 1989 and is widely recognized as a pioneer in the diesel performance segment. This valve is a genuine BD Diesel service part, engineered to meet the same standards as the original component found in BD exhaust brake kits.

Key Features:

• Direct OEM replacement quick release valve for BD Diesel exhaust brake systems
• Ensures rapid air pressure release from the actuating cylinder upon brake deactivation
• Compact form factor fits within existing exhaust brake pneumatic plumbing
• Sold as a single valve — quantity of one (1) per package
• GTIN: 00019025019683

This valve is an essential service part for maintaining peak performance of your BD Diesel exhaust brake. If debris or corrosion has compromised your existing quick release valve, replacing it with a genuine BD part restores proper brake response and protects the broader pneumatic system.
