Product Description
API 6-5/8" REG Drill Pipe Float Valve & Float Valve Sub
Float Valve Overview
The Drill Pipe Float Valve is installed in the standard bore-back of the bit sub to provide precise fluid flow control at the bottom of the drill stem. This critical component prevents backflow of cuttings from plugging drill bit jets during connections, ensuring uninterrupted drilling operations.
We manufacture a comprehensive line of Float Valves and Repair Kits designed to accommodate diverse drilling situations and challenging operating conditions.

Float Valve Sub Functionality
The Float Valve Sub is an essential tool in petroleum exploration and drilling engineering. Positioned at the upper part of the drill bit, the float valve assembly is located near the bit connecting thread and can be placed at necessary positions within the drill string.
Primary applications include preventing mud ingress, controlling mud return flow, and avoiding hole blockage. During blowout situations, the nozzle automatically closes via the valve cap, preventing blowout within the drill string.
