High performance universal dump valve GFB SV52

The SV52 is a high performance wastegate designed for extreme boost environments, with an impressive 300 psi capacity.

The GFB SV52 is an exceptional wastegate, designed for high-boost engines and extreme performance environments. Its piston design, high pressure capacity, and preload adjustments make it an ideal choice for those looking to maximize performance while maintaining long-lasting reliability.

Increased Reliability Under High Boost: The piston design provides long-term durability under the most extreme boost conditions, where a traditional diaphragm might fail.

Optimal Throttle Response: With dual springs and preload adjustment, the SV52 optimizes throttle response and recovery after shifts, improving overall engine performance.

Compact and robust design: The use of premium materials and a CNC machined design guarantee maximum performance in a compact format.

High Boost Pressure: The SV52 can handle an incredible 300 psi of boost pressure, making it an ideal wastegate for high pressure environments.

Spring Preload Adjustment: The valve comes with 2 springs and a preload adjustment system, allowing you to fine-tune throttle response and optimize recovery after shifting without the need to purchase additional springs.

Manifold Vacuum Compatibility: Fits engines with manifold vacuum between 5 and 22 inches of Hg (17 to 74.5 kPa or 2.5 to 11 psi), covering a wide range of engine configurations.

One-Piece Aluminum Body Design: The body is CNC machined from a single billet of aluminum, ensuring maximum strength while reducing unnecessary bulk for a compact size.

Anodized Piston and Viton O-Rings: The 52.5mm one-piece aluminum piston slides over an anodized bore, which provides a hard, low-friction surface for smooth, long-lasting operation. GFB's exclusive Viton O-rings provide excellent sealing, even under extreme pressure and temperature conditions.

Piston vs. Diaphragm Design: Unlike diaphragm designs, the SV52 uses a piston, which offers increased strength and reliability in high-boost environments. While diaphragms can fail under repeated pressure and rapid cycling, the piston is designed to operate smoothly under frequent pressure reversals, ensuring maximum longevity.

Compact Mounting Method: The unique design reduces the overall valve height by placing the piston and vent ports lower, eliminating the need for V-band mounts. This reduces the SV52's footprint while maintaining its peak performance.
