150# Cast Iron Butterfly Valve

A butterfly valve operates in a quarter turn to control the system flow. The disc of butterfly valve acts as a door in the pipeline, it rotates around a central axis to open or close the flow of fluid or gas. Butterfly valves provide benefits like minimal pressure drop, yet, it faces challenge in throttling applications with low pressure differences and might be influenced by choked flow. There are two types of butterfly valve which is lug type and wafer type.
