  1. Product Features
  1. Excellent Corrosion Resistance: ASTM B62 Aluminum Bronze offers superior resistance to seawater and brackish water corrosion, making it ideal for marine applications.
  2. Long Service Life: The material’s anti-galling and anti-seizing properties ensure smooth operation and long-term reliability.
  3. Tight Shut-off: Precision machined seat and disc provide bubble-tight sealing.
  4. Compliance: Designed, manufactured, and tested in accordance with international standards (MSS, ASME, API).
  5. Easy Maintenance: Bolted bonnet design allows for easy inspection and repair without removing the valve from the pipeline.
  1. アプリケーション
  • Marine & Shipbuilding: Seawater cooling systems, ballast systems, fire fighting.
  • Offshore Platforms: Seawater handling, utility systems.
  • Desalination Plants: Brine and seawater lines.
  • Industrial: Steam lines (low pressure), cooling water, and non-aggressive fluid control.
