The standard by which all other power valves are measured. QFT exclusive in-house design has become the power valve of preference by professional race teams in virtually every circuit where carburetors are used. Not only does the FOUR DOOR® power valve have a much greater flow capacity (vital for alcohol applications) but a quicker response rate and tighter limit bands allow engine builders to precisely tune the power enrichment phase of their calibration. Each FOUR DOOR® power valve is hand tested and set to the stamped value. The opening and closing specifications are 1/2 Inch HG above and below the stamped value. The thicker molded diaphragm adds increased protection against backfire induced rupture. No one offers a broader selection of opening values than QFT.
