Blow off Valves
Blow Off Valves, also known as diverter valves, bypass valves, or BOVs, help regulate boost by releasing excess pressure from turbocharged systems. This prevents compressor surge and protects turbo components. Based on the setup, the valve either recirculates the pressure or vents it to the atmosphere.
At NGR Performance, we manufacture high-quality solutions like the Type-S turbo blow off valve, crafted from 6061 billet aluminum. It delivers sharp throttle response and a signature sound, making it a favorite for both track and street builds.
Benefits of NGR Blow Off Valves:
- Reduces risk of turbo damage under high boost
- Supports both recirculating and atmospheric systems
- Diaphragms are pressure-tested up to 100 PSI
- Lightweight, durable construction for long-term use
- Compatible with various blow off valve adapters for easy installation
Whether you're upgrading or replacing a turbo pressure release valve, NGR ensures a precise fit and reliable performance.
