Test Pressure:
- Shell Test: 300 psi (Hydrostatic)
- Seat Test: 220 psi (Hydrostatic)
- Product Features
- Excellent Corrosion Resistance: ASTM B62 Aluminum Bronze offers superior resistance to seawater and brackish water corrosion, making it ideal for marine applications.
- Long Service Life: The material’s anti-galling and anti-seizing properties ensure smooth operation and long-term reliability.
- Tight Shut-off: Precision machined seat and disc provide bubble-tight sealing.
- Compliance: Designed, manufactured, and tested in accordance with international standards (MSS, ASME, API).
- Easy Maintenance: Bolted bonnet design allows for easy inspection and repair without removing the valve from the pipeline.
- Aplikasi
- 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.
