Instead of using high-end materials with high corrosion resistance like duplex stainless steel or Monel for the disk material!
Butterfly valves are commonly used in seawater lines for cooling pumps at power plants, ship-side valves in shipbuilding, and seawater desalination. In this case, since the seawater comes into contact with the disc, it is necessary to select materials with excellent corrosion resistance. The butterfly valves we handle (manufactured by Value Valve) can be equipped with rubber lining for seawater resistance. *For more details, please refer to the PDF materials or feel free to contact us. *We also have other technical materials available.
