DescriptionPower Valve Assembly; Hi Flow Four Door Power Valve; 4.0;
The standard by which all other power valves are measured. QFT's 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(R) power valve have a much greater flow capacity, vital for methanol 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(R) power v alve is hand tested and set to the stamped value. The opening and closing specifications are ½ inch HG above and below the stamped value. The thicker molded diaphragm adds increased protection against backfire induced rupture. This power valve design is covered by U.S. patent # 652,048,8B1.
