1/2" Mini Ball Valve – Compact Female x Female Design

The 1/2" female x female mini ball valve is designed for compact threaded systems where space is limited and reliable shut-off is required. This compact ball valve (also referred to as a small ball valve or miniature ball valve) is ideal for instrumentation lines, utility piping, OEM equipment, and installations where a full-size valve may be impractical.

Its compact single-body construction (single piece design) minimizes potential leak paths while maintaining durability and performance in demanding applications. Manufactured from 316 stainless steel, this mini ball valve provides corrosion resistance and long-term reliability in industrial and process environments.

The standard (reduced) port design supports controlled flow while allowing a smaller valve body than full-port alternatives. Compared to full port valves, the reduced bore helps maintain a compact footprint while still delivering dependable shut-off performance.

Rated to 1000 WOG, this threaded mini ball valve features female NPT connections on both ends for straightforward installation into standard 1/2" piping systems. PTFE seats provide reliable sealing performance, while the quarter-turn lever (flag) handle allows quick and simple shut-off operation.

Because of its compact design, this valve is commonly used in small diameter piping systems, compact valve installations, compressed air lines, and instrumentation setups where space efficiency and dependable shut-off are required.
