WEBER 40 DCOE/DCOM Throttle Plate Valve Butterfly 78° – MPN 64005.044

This throttle plate, also called a butterfly valve, controls the main airflow through the throttle bore of a Weber 40 DCOE or DCOM carburetor. Its 78° angle determines how the plate seats in the bore and how it follows the throttle shaft through the closed, progression, and open-throttle positions. 78° throttle plate angle is a critical identification point when replacing a worn or damaged butterfly.

A correctly matched plate supports proper closed-throttle positioning and smooth transition from the idle circuit into the progression and main circuits. A wrong angle, hole layout, or interface can prevent the plate from seating correctly, causing air leakage at idle, inconsistent progression, or difficulty synchronizing the carburetor. This part is also listed for Spanish, EMPI, and FAJS carburetors, late Italian types 28, 44, 45, 72, 73, 76, 77, 80, 81, 90, 91, 92, 93, and 151, and carburetors using a 3-hole bypass arrangement.

This replacement part is suitable for carburetor service and restoration work where the original component is worn, damaged, or missing.

Reference/MPN: 64005.044.

Technical role: 78° throttle plate butterfly controlling airflow through the Weber 40 DCOE/DCOM throttle bore.
Service relevance: Replacement for a worn or damaged butterfly to support correct closed-throttle seating and smooth progression.

Important Fitment Note

Verify the carburetor family and code before installation. Confirm the 78° plate angle, throttle-shaft hole pattern, plate geometry, seating profile, and screw or interface arrangement. The listed applications include Spanish, EMPI, FAJS, and late Italian carburetor types 28, 44, 45, 72, 73, 76, 77, 80, 81, 90, 91, 92, 93, and 151, including units with a 3-hole bypass arrangement.

Compare the replacement directly with the removed plate before fitting, including its angle, hole positions, edge profile, and throttle-shaft interface.
