“In diamond drilling operations, the NQ, HQ, and PQ shut-off valves stand as crucial components within the drill string. These valves play a vital role in regulating the flow of drilling fluid or mud, tailored to the specific sizes of drill rods used.

“NQ,” “HQ,” and “PQ” signify distinct sizes of drill rods:

• NQ: Typically around 2.375 inches (60.3 mm) in diameter.
• HQ: Featuring a larger diameter, usually around 3.5 inches (88.9 mm).
• PQ: The largest of the three, with a diameter typically around 4.75 inches (120.6 mm).

Despite the differences in rod size, the shut-off valves associated with each perform similar functions, finely tuned to their respective diameters.

These valves offer several advantages:

• Flow Regulation: Allowing drillers precise control over drilling fluid or mud flow through the string, vital for maintaining optimal drilling conditions.
• Safety Measures: Promptly shutting off fluid flow enhances safety on-site, averting potential hazards or spills.
• Operational Efficiency: By ensuring precise fluid control, these valves bolster overall drilling efficiency, leading to smoother operations and heightened productivity.

In essence, the NQ, HQ, and PQ shut-off valves are indispensable elements, guaranteeing safety, efficiency, and control in diamond drilling operations across varying drill rod sizes.”
