Product Overview
The KOZO C95800 Aluminum Bronze Triple Offset Butterfly Valve is designed for seawater, marine and offshore service where nickel-aluminum bronze construction and metal-seated quarter-turn isolation are required. Triple-offset geometry minimizes rubbing between the disc seal and seat during most of the travel, helping reduce wear in demanding cycling applications.
Why C95800?
ASTM B148 C95800 nickel-aluminum bronze is widely used in marine valves, pumps and seawater equipment. Final suitability depends on water chemistry, flow velocity, temperature and the complete valve material combination.
Key Design Features
- Triple-offset geometry: Reduces sliding contact between disc seal and seat.
- Metal-seat configuration: Suitable for demanding marine isolation service.
- C95800 body: Nickel-aluminum bronze for marine and compatible corrosive environments.
- Multiple pressure classes: 班级 150/300/600 family.
- Manual or automated operation: Gear, pneumatic or electric actuation can be selected.
