The unique designassures that the stop action occurs below the lockingplate surface, not on the top where debris could impedethe square from & s body is actuallystronger than the pipeline.
6 Note the low stresslevels (blue color) as compared to pipeline(yellow color). Yet its design allows forflexibility without BREAK. The patented, cast steelUltra-Stop is an integral part of the 2 operating square. If over-torqued, Ultra-Stopbreaks cleanly from the square preventingany valve some of the most extensive tests performed on avalve, the Kerotest WELDBALL Gas Distribution Valveconsistently meets and exceeds industry standards fordesign and performance. Use it with confidence indistribution services, meter and regulator stations,system blow down applications, hot tap applications andother applications that demand a positive Kerotest Full Port and Reduced Port Valves come inbutt weld, flanged, and weld by flange 150 rated valves are available in sizes 3/4 through12 , while Class 300 rated valves are available in sizes3/4 through 10.
