- DN 65 to 600
Pressure Class Range:
- 150 to 1500
- PN 25 to 260
Seating Material: Metal, Soft
Features and Benefits
- 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
