Two Piece Kelly Valves
The Global two piece kelly valve is a manually operated ball valve with a positive 90 degree rotation. The two piece kelly valve is located above and below the kelly to close off the flow of fluid through the bore of the drill string. The two piece kelly valve on the lower end of the kelly can also be used as a mud saver by closing the valve before breaking a tool joint connection. Global two piece kelly valves are manufactured to API Specifications for rotary drilling equipment.
