Medical F.A. Valve

DESCRIPTION

In the medical world, an F.A. Valve most commonly refers to a Fine Adjustment Valve. These are precision components used in respiratory therapy and anesthesia to control the flow of gases (like oxygen or nitrous oxide) with extreme accuracy.

Unlike a standard on/off valve, an F.A. valve is designed for incremental control.

• Precision Threading: They use very fine internal threads so that a full turn of the knob only results in a tiny change in gas flow.

• Needle Valve Design: Most F.A. valves are “needle valves,” where a long, tapered point fits into a seat to restrict or allow flow.

• Material: Usually made of chrome-plated brass or stainless steel to ensure they are non-reactive and easy to sterilize.

  Why “Fine Adjustment” Matters

  In medical environments, especially neonatal or intensive care, a gas flow that is slightly too high or too low can be dangerous. The F.A. valve allows clinicians to dial in specific flow rates—often measured in fractions of a liter—to match a patient’s exact physiological needs.
