Weldball Flanged End Standard Port |
| |
Benefits & Features
In some of the most extensive tests performed on a valve, the Kerotest Weldball® Gas Distribution Valve consistently meets and exceeds industry standards for design and performance. For use in distribution services, meter and regulator stations, system blow down applications, hot tap applications, and other applications that demand a positive shut-off.
The Weldball Class 150 & Class 300 rated gas distribution ball valves feature the exclusive Ultra-Stop design. This unique stop collar design eliminates the need for a shear pin and facilitates easier stem packing replacement.
The failure torque of the Ultra-Stop design provides the ultimate over-torque protection when operating a WELDBALL valve. The unique design assures that the stop action occurs below the locking plate surface, not on the top where debris could impede the square from turning. |
