Marine Bronze Butterfly Valve

Certified Reliability for Marine & Offshore Applications

The Marine Bronze Butterfly Valve is specially engineered for shipboard and marine piping systems, where long-term reliability and corrosion resistance are essential. Manufactured from high-quality bronze or aluminum bronze alloys, this valve delivers excellent performance in seawater, salt spray, and harsh marine environments.

With a compact structure and quick quarter-turn operation, it is an ideal solution for both on/off service and flow regulation in marine applications.

Key Advantages

Outstanding Seawater Corrosion Resistance
Marine-grade bronze and aluminum bronze materials provide excellent resistance to seawater corrosion, erosion, and biofouling, ensuring long service life in demanding marine conditions.

Compact & Lightweight Design
The butterfly valve design minimizes weight and installation space, making it especially suitable for shipboard systems with limited space.

Quick & Efficient Operation
A 90° quarter-turn mechanism allows fast opening and closing, improving operational efficiency and system response.

Flexible Installation Options
Available in wafer, lug, and flanged types, compatible with various marine piping standards.

Multiple Actuation Options
Manual lever, worm gear, pneumatic, or electric actuators are available to meet different operating and automation requirements.

Classification Society Approval Available
