Description
A Stainless Steel 304 Ball Valve with Screw End is a quarter-turn valve that uses a spherical ball with a bore to control flow. It is operated by turning a lever or handle 90°, providing quick on/off operation and tight shut-off. The screw (threaded) ends make these valves ideal for compact pipeline installations, where flanged or welded ends are not required. SS 304 construction provides excellent corrosion resistance and suitability for water, oil, gas, and many chemical services.
