• Broad application flexibility provided by the variety of available body types
• High-performance ensured by a cast body with large radius curves designed to optimize internal flow passages and minimize pressure drops
• Improved reliability and service integrity via body-guided disc design to ensure tight sealing and check valve protection in the event of fluid back flow
• Ease of maintenance facilitated by the seal-welded seat ring, which allows for quick replacement
• Rapid operation made possible by the optional equalizer lines that connect the bonnet area above the disc to the downstream port
• Optional equalizer lines improve disc lift and eliminate dash-pot effect
