Set of 4 Weber 45 DCOE 45 mm 78° Butterfly Valves

This set of 4 Weber 45 DCOE butterflys is intended for the maintenance and repair of 45 mm dual-barrel Weber carburetors. Each butterfly has a diameter of 45 mm and a 78° angle, in accordance with this carburetor configuration.

Installed on the carburetor shaft, this component controls the airflow into the carburetor based on the position of the throttle. Its closure within the carburetor body also plays an essential role in the engine’s proper idling operation.

Replacing the butterfly valves may be necessary when overhauling a Weber 45 DCOE carburetor, particularly when the existing parts show wear or damage that could affect their positioning or closure.

The 78° angle is an important mounting specification. Before replacement, check the diameter and angle indicated on the original butterfly valves to select the configuration that exactly matches your carburetor.

The product is supplied in a set of 4 butterfly valves—the quantity needed to equip all four bodies in a system using two Weber 45 DCOE carburetors.
