needle valve

Precision flow controller

A needle valve is a valve with a slender, tapered point that fits into a conical seat, allowing precise control of fluid flow.

The needle-like stem can be adjusted incrementally, making these valves essential where fine regulation matters—in carburetors, laboratory equipment, and hydraulic systems.

Adjust the needle valve to control the fuel mixture.
