CL 800 PN 140 bar class ball valves in the 3-piece super duplex are not only robust and efficient for flow control in pipelines but are specially designed to withstand extreme conditions.
Their super duplex construction, with a PREn greater than 40, makes them ideal for marine and corrosive seawater environments. They are perfectly suited for applications in ships, desalination systems, and other scenarios where corrosion resistance or marine or near-sea environment is paramount.
Importantly, all hardware on these valves is 316 stainless steel, ensuring additional durability and strength. The parts of the valve that come in direct contact with the fluid are manufactured in either super duplex or Inconel, providing increased corrosion resistance and ensuring the integrity of the valve even in the most challenging conditions.
