Product Details

The Edelbrock 12635 is a single-stage power valve designed to optimize carburetor performance during high-load driving conditions. This vacuum-operated component opens at 3.5" Hg (inches of mercury) to deliver additional fuel to the main metering system when engine vacuum drops under acceleration or heavy load.

Key Features:

  • Single-stage design for precise fuel enrichment control
  • Opens at 3.5" Hg vacuum signal for consistent operation
  • Prevents hesitation and bogging during acceleration
  • Ensures smooth power delivery under full throttle conditions
  • Direct replacement for compatible Edelbrock carburetors
  • Quality construction for reliable long-term performance

Power valves are critical tuning components in performance carburetors. When engine vacuum decreases during acceleration or load, the power valve opens to provide the additional fuel needed for optimal air-fuel ratios. Selecting the correct power valve opening point based on your engine's vacuum characteristics is essential for eliminating flat spots and maintaining strong acceleration throughout the RPM range.
