Y-Pattern, High Flow
Y-Pattern Globe Valve
High-capacity throttling with significantly lower pressure drop than standard globe valves
The Y-pattern body design angles the seat at 45° to the flow axis, dramatically reducing turbulence and pressure drop compared to conventional globe valves. This makes it the preferred choice for high-pressure steam, oil, and gas applications where flow efficiency matters.
