  1. Valve discs are positioned in line with the flow. These lock each other open, offering minimum headloss
  2. The combined energy of the bias springs and product velocity flips the discs through a controlled arc.
  3. The discs continue to rotate until they have moved through 90 degrees.
  4. The discs snap onto their seats; providing 100% leak-free shut-off.
