A power valve with 5.0 inch opening vacuum from Holley, model 125-50, delivers single-stage fuel metering control for performance carburetors and engines. Opening at 5.0 inches of mercury, this single-stage valve enables engine vacuum to regulate fuel delivery, automatically adjusting to different engine loads and driving conditions for consistent performance throughout the operating RPM range. The performance-grade valve comes complete with gasket seal and functions as a single-stage unit, which distinguishes it from dual-stage power valve designs. Standard flow configuration makes it compatible with most performance carburetor applications.
