- Lower valve recovery factor and higher Cv per given size over traditional globe style valves due to the nearly straight-through passage of the Y-style body
- Significantly reduced noise and vibration owing to less restrictive body style, which generates less line turbulence
- Easy, low-cost maintenance and extremely tight shutoff made possible by clamped-in seat and self-aligning seat ringDecreased inventory carrying costs from a high degree of interchangeability with Mark One Series valves
