Legend Cast Iron Flange Check Valves
Legend Cast Iron Check Valves
Legend Cast Iron Check Valves are built for dependable backflow prevention in commercial, municipal, and industrial piping systems. Designed to automatically allow fluid to flow in one direction while preventing reverse flow, these valves help protect pumps, compressors, and pipelines from costly damage. With rugged cast iron construction and proven internal designs, Legend check valves deliver long-lasting performance in high-volume and heavy-duty applications.
Reliable Backflow Prevention
Automatic One-Way Operation
Legend cast iron check valves operate using system flow and pressure, requiring no manual control. When fluid moves forward, the valve opens to allow passage; when flow reverses, the valve closes quickly to prevent backflow. This automatic action enhances system safety and protects critical equipment.
Reduced Maintenance Design
With simple internal components and fewer moving parts, cast iron check valves offer reliable operation with minimal maintenance. Their durable construction ensures consistent performance over extended service life.
Types of Cast Iron Check Valves
Swing Check Valves
Swing check valves feature a hinged disc that swings open with forward flow and closes when flow reverses. They are ideal for low-pressure systems and applications requiring minimal flow resistance.
Tilting Disc Check Valves
Tilting disc designs provide faster closure than traditional swing checks, helping reduce water hammer and pressure surges. These are commonly used in higher-pressure or high-flow systems.
Lift Check Valves
Lift check valves use a guided disc that lifts off the seat as flow increases and returns to close when flow stops. They are suitable for systems requiring tighter sealing and more controlled operation.
