The C95800 nickel-aluminum bronze ball valve is a high-performance valve featuring a top-loading design that reduces the number of connecting bolts and enhances sealing reliability. This design minimizes the impact of its own weight on normal valve operation under high-pressure, large-diameter conditions, thereby improving overall stability.
1. Material Characteristics:
- Cast from ASTM B148 C95800 nickel-aluminum bronze alloy
- Contains 4-6% nickel, 8.5-10% aluminum, and 3-5% iron
- Excellent resistance to seawater corrosion
- Tensile strength ≥550MPa as specified by ASTM B61 standard
2. Mechanical Properties:
- Working pressure up to PN16-PN40 (150LB-300LB)
- Operating temperature range -20°C to +250°C
- NACE MR0175 certified resistance to hydrogen sulfide stress cracking
3. Application Advantages:
• Particularly suitable for corrosive media environments such as seawater and brine
• Ideal choice for harsh conditions such as LNG receiving terminals and offshore platforms
