DV+ Diverter Valve

The GFB DV+ T9366 is a performance diverter valve engineered to replace the factory-fitted valve found in various European vehicles. This DV+ solution addresses the common weaknesses of stock diverter valves, such as diaphragm rupture and plastic component failure, which can lead to boost leaks and potential damage. By retaining the factory solenoid coil, the DV+ ensures seamless integration with the vehicle's ECU, maintaining the rapid actuation speed that pneumatic valves cannot match. The weak points of the stock system are replaced with robust metal components: an anodized billet aluminum housing and a brass piston machined to exacting tolerances. This construction guarantees strength and reliability, even under high boost conditions. GFB's innovative pilot-actuation system further enhances performance. Instead of the solenoid directly actuating the piston, it controls airflow to a small passage that then actuates the piston. This design ensures the valve opens and closes reliably regardless of boost pressure. Additionally, the pilot-actuation allows for progressive valve opening based on boost pressure, meaning it only opens as much as needed, leading to improved throttle response and faster boost recovery on gear shifts. This also helps prevent compressor surge and turbo flutter, unlike many traditional replacement kits that rely on fully pneumatic systems with added complexity and slower response times. The DV+ T9366 is a direct-fit replacement, designed for straightforward installation without the need for extra components like vacuum hoses or mounting brackets. It offers sharper throttle response, resolves boost leaking issues, and is built to last, providing a cost-effective performance upgrade without unnecessary complexity or price. It is important to purchase from approved dealers to ensure authenticity, as counterfeit products are known to exist.
