Key Features

• Mechanical EGR valve design for emission system service
• Stainless steel valve components for added durability
• Polyester-reinforced silicone diaphragm resists thermal aging up to 200°C
• Reinforced gasket included for complete replacement
• 1 hose connector and 2 bolt holes for the specified application
• Standard Ignition EGV391 replacement part number

Detailed Description

Standard Ignition EGV391 is an exhaust gas recirculation valve engineered for vehicles that use a mechanical EGR setup. The valve uses stainless steel internal components and a polyester-reinforced silicone diaphragm to handle heat exposure and long-term service in emission control systems. For buyers searching for a 1980 Chevrolet K10 Suburban EGR valve, 1980 Chevrolet K20 EGR valve, or 1980 GMC K2500 EGR valve, this part matches the listed OE application and supports proper exhaust gas recirculation function. This part cross-references Karlyn 30345 for the same application.

Common Issues This Part Can Address

• Rough idle caused by an EGR valve that no longer opens or closes correctly
• Emission test failure related to improper exhaust gas recirculation flow
• Driveability problems from carbon buildup or diaphragm wear in the EGR valve
• Vacuum or mechanical control issues in the emission system
• Replacement needs for a worn OE No. 17063340 valve

Installation Notes and Tips

Verify the vehicle’s OE number and mounting style before installation. The EGV391 uses a mechanical design with one hose connector and two bolt holes, so the replacement should match the original configuration on the vehicle. Clean the mounting surface thoroughly and use the included gasket to help ensure a proper seal during installation.

Quality Assurance

Standard Ignition manufactures emission components with quality control maintained throughout the production process, from individual components to the finished valve. The stainless steel construction and heat-resistant diaphragm support consistent performance in demanding exhaust gas recirculation service.
