Description GARRETT 914956-0002 Blow-Off Valve VTA GVB-50A 50 mm Blue

The GARRETT 914956-0002 VTA GVB-50A in blue is a high-flow 50 mm blow-off valve engineered by the same team behind G-Series turbochargers and GVW wastegates. Optimized through advanced CFD design, it delivers airflow up to 350 CFM / 0.21 kg/s (GVB-50R RCV), ensuring precise boost control and maximum efficiency. The Nomex-reinforced high-temperature diaphragm guarantees durability under extreme conditions, while the plated stem and bushing reduce friction and wear. The valve is pre-set to 10 PSI base pressure and includes multiple spring options for fine-tuning between 3 and 13 PSI. Each kit is supplied with all fasteners, fittings, V-bands, clamps, flanges, and springs for a complete installation.
