Features
03Advantages
- Smooth, balanced closing: reduces the risk of water hammer
- Low cracking pressure: operates with minimal system load
- Fast response: particularly effective at pump discharges
- Long service life: wear-resistant disc and hinge system
- High flow capacity: minimal resistance when fully open
Applications
- Pump discharges (especially large-diameter systems)
- Power plants (cooling water, condensate lines)
- Oil and gas lines
- Fire-fighting systems
- Marine and ship machinery
- Industrial process water systems
Options and accessories
- Spring-assisted closing: faster closing, maximum protection against water hammer
- Hydraulic damper: controls the closing speed of the disc and prevents vibration
- Backflow monitoring port: allows checks before maintenance
- Tight-sealing design: leakage rate determined to EN 12266-1
