Premium Al-Bronze Concentric Butterfly Valve by CTGV
Al-Bronze (Aluminum Bronze) concentric butterfly valves are designed for corrosive and marine environments, offering superior seawater resistance, durability, and anti-biofouling properties. They are widely used in shipbuilding, offshore platforms, desalination plants, and chemical processing.
1. Corrosion Resistance
Excellent for seawater, brine, and chlorinated water (resists pitting and crevice corrosion).
Superior to standard stainless steel (316) in high-salinity environments.
2. Anti-Biofouling Properties
Copper content inhibits marine growth (algae, barnacles), reducing maintenance.
3. High Strength & Wear Resistance
Harder than standard bronze, suitable for slurries and abrasive fluids.
4.Lightweight & Compact
Easier to install than steel valves, ideal for marine and offshore applications.
5.Bubble-Tight Sealing (Soft Seat Options)
Available with EPDM, NBR, or Viton seats for zero-leakage shut-off.
