maradyne power fluid high pressure ball valves

Ball Valves

Our high pressure ball valves feature our “Floating Ball” design, insuring a positive, leak-free seal that automatically compensates for any seat wear or misalignment. Available in carbon steel or stainless steel, featuring:


  • 1/4″ turn position operation.
  • Hard-chrome plated micro-smooth ball greatly reduces friction and seat wear.
  • Full size ports on most two-way valves virtually eliminates pressure drop.
  • Maradyne Ball Valves offer completely bidirectional operation, eliminating any chance of incorrect installation.
  • Long seal life.


Maradyne Power Fluid ball valves are easily and fully repairable and require NO lubrication or maintenance for the entire life of the valve.
