Cast Steel Butterfly Valves

Categories

Constructed with a cast steel body and disc, operated by handwheel, gear, or actuator. A shut‑off and throttling valve designed specifically for higher‑pressure, higher‑temperature services where carbon steel isn’t enough.

This valve is at home in steam, hot oil, refinery utility, and power plant auxiliary systems. Carbon steel lacks strength at 600LB/400°C; stainless steel is overkill. Cast steel hits the sweet spot – higher pressure capability without the premium cost. Longer seat life and fewer unplanned outages – that’s what cast steel delivers.
