Description
Holley Single-Stage Power Valve (7.5 in. Hg)
Precision fuel enrichment component for Holley performance carburetors, regulating fuel flow under low manifold vacuum load conditions.
Product Overview
The Holley 125-75 is a genuine single-stage standard flow power valve engineered to enrich the main metering circuit during acceleration and low manifold vacuum scenarios. Calibrated to open precisely at 7.5 in. Hg (Inches of Mercury), this component ensures optimal air-fuel ratios during part-throttle transitions and heavy engine loads without sacrificing idle quality.
Built to exact factory tolerances, it features a heavy-duty internal diaphragm and durable valve seat designed for rapid response to vacuum changes. Each unit comes complete with a fresh mounting gasket washer to ensure a leak-free seal upon installation into your Holley carburetor metering block.
