Edelbrock Single-Stage Power Valve Standard Flow 5 5 In Hg

What you get here is a single-stage power valve from Edelbrock, designed to work with Holley, Demon, and Quick Fuel carburetors. This valve uses engine vacuum to control when it opens and closes. When you're really putting the pedal down, like during heavy acceleration or full throttle, this valve opens up to add more fuel to your carburetor's main system. This helps prevent that hesitation or bogging down you might feel, ensuring your engine runs smoothly and delivers power without any drivability issues.

This standard flow valve is set to open at 5.5 inches of mercury (in. Hg). It's a well-built component that helps keep your performance carburetor in top running order. It's a common part to replace during a carburetor rebuild or if you're experiencing drivability problems under load.
