Wafer Type Butterfly Valves – Compact Flow Control Solutions
- Wafer type butterfly valves are compact flow control valves designed for shipboard and offshore piping systems.
- Regulate or isolate fluid flow using a rotating disc mounted on a central shaft.
- Wafer design allows installation between pipe flanges, saving space.
- Ideal for marine applications where installation space is limited.
Function in Marine Systems
- Used to control, regulate, or shut off fluid flow.
- Disc rotates 90 degrees between open and closed positions.
- Enables fast operation and efficient flow control.
- Suitable for large-diameter pipelines commonly found on vessels.
Marine Applications
- Seawater and freshwater cooling systems.
- Ballast and bilge pipelines.
- Firefighting and safety systems.
- HVAC and accommodation systems.
- Auxiliary, utility piping, and offshore installations.
Valve Design and Operation
- Installed between two pipe flanges and secured using flange bolts.
- Central disc allows partial or full flow control.
- Reduces installation time and overall system weight.
- Maintains reliable sealing performance during operation.
Materials and Construction
- Cast iron or ductile iron bodies with marine-grade protective coatings.
- Stainless steel discs for enhanced corrosion resistance.
- Rubber or elastomer liners suitable for marine fluids.
- Alloy steel shafts designed for continuous marine operation.
Performance Advantages
- Compact and lightweight construction.
- Quick operation with minimal torque.
- Well-suited for large-diameter marine pipelines.
- Reduced installation space and overall system cost.
- Dependable sealing performance.
Suitability for Marine Environments
- Designed to withstand corrosive marine conditions and saltwater exposure.
- Reliable performance under vibration and temperature variation.
- Simple design supports long service life.
- Widely used in commercial vessels, offshore units, and port facilities.
Efficient Flow Control for Marine Operations
- Marine wafer type butterfly valves provide efficient flow regulation.
- Compact design supports space-constrained installations.
- Ensure safe operation and system efficiency.
- Reliable valve solutions for shipboard and offshore environments.
