Cast Iron Lug Type Butterfly Valve
The Cast Iron Lug Type Butterfly Valve is a heavy-duty valve designed for reliable flow isolation and regulation in industrial and utility pipelines. Its lug-style body, fitted with threaded inserts, allows it to be installed between flanges and enables pipeline maintenance from one side without disturbing the opposite end. Constructed with a robust cast iron body and a resilient sealing seat, it offers bubble-tight shut-off and smooth quarter-turn operation, making it ideal for water, oil, gas, and chemical systems.
