SHUANGLIN VALVE | FxF Mini Ball Valve, DN6–DN25

Sometimes the only thing a small fitting needs is a reliable, no-fuss way to turn the flow on or off. SHUANGLIN VALVE's FxF mini ball valve does exactly that — a compact, quarter-turn shut-off with female threads on both ends, built to drop into a line between two male-threaded fittings without adding unnecessary bulk.

A Straightforward Shut-Off, Built to Last

Inside, a chrome-plated brass ball rotates a quarter turn to open or close the flow path completely, giving instant visual confirmation of valve status from the handle position — in line with flow, it's open; across the line, it's closed. The compact hex body and polished chrome finish keep the valve small and corrosion-resistant, suited to sitting exposed in visible plumbing runs, under sinks, or inline on appliance connections without looking out of place.

Fits Where Space Is Tight

Because both ports are female-threaded, this valve installs directly between two male-threaded nipples or fitting ends — a straightforward substitution wherever a section of pipe currently has no shut-off point. This makes it a practical retrofit option for adding isolation to an existing line without reworking the surrounding fittings. SHUANGLIN VALVE produces this valve across the DN6 to DN25 size range, covering everything from small instrumentation and gauge lines up to standard 1-inch plumbing connections.

Frequently Asked Questions

Can this valve be installed directly onto a female-threaded pipe? No — since both ends are female-threaded, this version requires a male-threaded nipple or fitting on at least one side. For direct connection to a female port, our FxM (male x female) mini ball valve is the better fit.

Does the handle position show whether the valve is open or closed? Yes. When the handle is aligned with the pipe, the valve is open; when it's turned 90 degrees across the pipe, the valve is closed — giving an immediate visual check without needing to test the flow.
