Holley Single-Stage Power Valve 125-95
The Holley 125-95 power valve is an important component in the power enrichment circuit of Holley's performance carburetors. These power valves operate by using engine vacuum to control their opening and closing rate.
Key Features
- Single-stage design with standard flow characteristics
- 9.5 in. Hg opening vacuum for precise fuel delivery timing
- Includes gasket for proper installation
- Compatible with Holley 2010, 2300, 4010/4011, 4150, 4160, 4165, and 4175 carburetors
- Also fits Holley Carter AFB and AVS, Demon Race, Speed and Road, and Edelbrock Performer Square Flange carburetors
Function
When the power valve opens, additional fuel is supplied to the main system during heavy load or under full power situations to eliminate hesitation and bogging, ensuring the smooth delivery of power without any drivability concerns. The 9.5 in. Hg specification determines the vacuum level at which the valve opens, allowing for precise tuning of the fuel enrichment system.
Quality Assurance
This is a genuine Holley factory part that meets OEM specifications and quality standards. All Holley performance carburetors built since 1992 have utilized a power valve check system that effectively protects the power valve diaphragm from damage due to engine backfire.
