Description
A Stainless Steel 304 Ball Valve with Flanged Ends is a quarter-turn shut-off valve that uses a precision machined SS 304 ball to control flow. When the handle is turned 90°, the ball bore rotates to open or close the valve, providing quick operation and tight shut-off. Flanged ends allow easy installation into piping systems, reliable sealing against gaskets, and are ideal for medium to heavy-duty industrial services including liquids, gases, and steam.
