Proflow brake proportioning valves offer outstanding versatility, allowing adjustments between 100 and 3,000 PSI (depending on the specific model) with a simple twist of a knob or the flip of a lever. This streamlined design, exemplified by the pfe386 proflow billet series, ensures that most models can reduce pressure by up to 57%, providing customers with a highly effective brake proportioning valve solution. The aluminium brake proportioning design enables precise tuning of brake bias, accommodating varying track conditions and differences in tire sizes, which is essential for optimizing performance and safety. This combination of robust construction and easy adjustability makes Proflow products a reliable choice for achieving the ideal balance between responsiveness and control during demanding situations.
