Product Advantages

Excellent Corrosion Resistance
Aluminum bronze provides strong resistance to seawater, saltwater, and corrosive environments, making it ideal for marine and offshore applications.
High Mechanical Strength
The valve offers excellent strength and wear resistance, ensuring reliable performance under demanding operating conditions.
Long Service Life
High-quality aluminum bronze construction helps reduce corrosion-related damage and extends valve service life.
Low Operating Torque
The compact butterfly design requires relatively low operating torque, allowing easy manual or automated operation.
Wide Application Range
Suitable for seawater cooling, desalination plants, shipbuilding, offshore platforms, fire protection, and industrial pipelines.
Flexible Actuation Options
Available with lever, gearbox, pneumatic, or electric actuators to meet different control requirements.
Easy Installation and Maintenance
Compact construction and lightweight design simplify installation, inspection, replacement, and routine maintenance.
Multiple Material Options
C95400, C95500, and C95800/Nickel Aluminum Bronze materials can be selected according to pressure, temperature, and corrosion conditions.

In terms of operation, these valves provide quick opening and closing, typically achieved with a 90 - degree rotation of the handle or actuator. This rapid response makes them suitable for applications requiring frequent on - off control. The streamlined disc design minimizes flow resistance, ensuring low pressure drop and high flow capacity, which improves system efficiency and reduces energy consumption.
