Marine Butterfly Valve

Product Features

·  Corrosion-Resistant Construction – Designed with durable materials suitable for seawater, salt spray, and harsh marine environments.

·  Compact and Lightweight – Space-saving construction makes installation and handling easier in shipboard and offshore piping systems.

·  Quick Quarter-Turn Operation – The 90° operating mechanism allows fast and efficient opening, closing, and flow isolation.

·  Reliable Sealing – High-quality seat and sealing components provide dependable shutoff and help minimize leakage.

·  Low Operating Torque – Optimized disc and stem design enables smooth operation with reduced operating effort.

·  Low Maintenance – Simple construction and fewer internal components help reduce maintenance requirements.

·  Good Flow Control – The disc design provides efficient flow regulation with relatively low pressure loss.

·  Multiple Configurations – Available in different sizes, pressure ratings, materials, and connection types to suit various marine applications.

·  Reliable Marine Performance – Designed to withstand vibration, pressure fluctuations, and demanding operating conditions on ships and offshore facilities.

Applications

Marine butterfly valves are widely used for flow control and pipeline isolation in ships, offshore platforms, and marine equipment. Typical applications include:

• Seawater Systems – Used for controlling seawater intake, discharge, and circulation.

• Ballast Water Systems – Provides reliable isolation and flow control in ballast piping.

• Cooling Water Systems – Suitable for engine, machinery, and equipment cooling circuits.

• Fire Protection Systems – Used in marine firefighting and fire-water piping.

• Bilge Systems – Helps control and isolate bilge water pipelines.

• Freshwater Systems – Used in potable, service, and utility water piping.

• HVAC Systems – Suitable for chilled water and cooling water circulation systems.

• Offshore Platforms – Used in utility, process, and seawater piping applications.

• Shipbuilding – Suitable for cargo ships, tankers, container vessels, workboats, and other marine vessels.
