  2. Pressure Drop: Butterfly valves can create significant pressure drop across the valve when fully open, leading to increased energy consumption for pump operation. This inefficiency can impact fuel consumption and operational costs for marine vessels.
  3. Limited Control Range: Traditional butterfly valves have a limited control range compared to other valve types, such as globe valves. This limitation can restrict precise flow control, especially in applications requiring fine adjustments.
  4. Seal Leakage: Over time, the seals of traditional butterfly valves may experience wear and tear, resulting in potential leakage. This can lead to product loss, safety concerns, and environmental consequences if the fluid being transported is hazardous or polluting.
  5. Corrosion Susceptibility: Marine environments are highly corrosive, and traditional butterfly valves made of standard materials may be susceptible to corrosion. Corrosion can compromise the valve’s structural integrity and affect its overall reliability and lifespan.
  6. Limited Environmental Features: Traditional butterfly valves may lack advanced environmental features, such as low-emission seals or materials that minimize ecological impact. This can hinder efforts to reduce the environmental footprint of marine operations.

To address these limitations, there is a growing emphasis on developing advanced butterfly valve technologies. That focus on improving efficiency, reliability, and environmental impact. These innovations include the use of specialized materials. Improved seal designs, aerodynamic improvements, and the integration of smart technologies for enhanced control and monitoring.
