Superduplex Ball Valves
Do you need more info? Here you can download the technical datasheet of this product.
Three-piece CL 800 PN 140 bar superduplex ball valves provide robust, effective flow control in piping systems and are specifically designed to withstand extreme conditions.
Their superduplex construction, with a PREn above 40, makes them ideal for marine environments and corrosive seawater service. They are well suited to vessels, desalination systems and other applications where corrosion resistance in marine or coastal environments is essential.
All valve fasteners are made from 316 stainless steel for additional durability and strength. The parts in direct contact with the fluid are made from either superduplex or Inconel, providing greater corrosion resistance and maintaining valve integrity even under challenging conditions.
