WEBER 45 DCOE Throttle plate valve butterfly 78° with countersunk screws$ 21 ‹ › ‹ › ‹ › ‹ › ‹ › Part number: ST3701Made in: EUIncludes:WEBER 45 DCOE 78° Throttle Plate Valve Butterfly with Countersunk Screws This throttle plate valve, also called a butterfly plate, is used in WEBER 45 DCOE carburetor throttle assemblies. It regulates airflow through the throttle bore as the shaft rotates from the closed position toward wide open throttle. The plate angle and mounting interface are important for correct throttle-shaft alignment, bore sealing, progression behavior, and transient response. 78° throttle plate angle The plate is marked 78° and is supplied with countersunk screws for attachment to the throttle shaft. During carburetor service, a worn, damaged, or incorrectly matched butterfly can contribute to inconsistent idle closure, air leakage at the throttle bore, poor progression control, or difficulty synchronizing multiple barrels. Confirm the shaft position and plate orientation before final tightening. This replacement part is suitable for carburetor service and restoration work where the original component is worn, damaged, or missing. Reference/MPN: 45valve. Technical role: The 78° butterfly plate regulates airflow in a WEBER 45 DCOE throttle bore as the shaft rotates. Service relevance: It replaces a worn or damaged throttle plate and includes countersunk screws for throttle-shaft attachment. What Is Included WEBER 45 DCOE 78° throttle plate valve butterflyCountersunk screwsMade in EU. Important Fitment Note Verify that your carburetor is from the WEBER 45 DCOE family and compare the removed plate before installation. Check the 78° marking, plate diameter and outline, countersunk screw-hole layout, shaft interface, screw engagement, and the way the plate seats within the throttle bore. Confirm that the replacement plate matches the original closed-position orientation and does not bind against the bore. Compare the code, geometry, and screw interface with the removed part before fitting. Carburetor variations and previous modifications can affect throttle-plate compatibility even within the same model family.What you see is what you getShow all parts
