Finolex 3PVC Gear Type Butterfly Valve

A butterfly valve is a type of quarter-turn valve used to regulate flow in a pipeline. It consists of a circular disc or plate that pivots on a central axis perpendicular to the direction of flow. When the valve is fully open, the disc is positioned parallel to the flow, allowing for minimal obstruction and maximum flow. Conversely, when the valve is closed, the disc is turned perpendicular to the flow, effectively blocking it.

Key components of a butterfly valve include the disc, stem, actuator, and seat. The disc can be made of metal or other materials, and it typically has a shape resembling that of a butterfly, hence the name. The stem connects the disc to the actuator, which is responsible for controlling the valve's position (open or closed). The seat forms a seal around the disc to prevent leakage when the valve is closed.
