Designed with a 150lb pressure rating and featuring a reliable OS&Y (Outside Screw and Yoke) design, these valves provide clear visual indication of the valve position, ensuring operational safety and ease of maintenance.
A key feature of this product line is its availability in an extensive range of large diameters, from 2 inches all the way up to 40 inches, making it an ideal solution for main water lines, power generation facilities, and large-scale process plants.
