Quick Overview

Single Stage Power Valve (includes gasket)

Opening Vacuum: 4.5" Hg

The power valve is a key component of the vacuum operated power enrichment system of Holley performance carburetors. The power enrichment system supplies additional fuel to the main system during heavy load or full power situations. A selection of power valves are available to “time" this system's operation to your specific requirements. Each Holley power valve is stamped with a number to indicate its vacuum opening point. For example, the number "“65" indicates that the power valve will open when the engine vacuum drops to 6.5" Hg, or below.
