Ball valves are isolation valves that control the flow of liquids or gases by means of a rotating ball with a bore. By rotating the ball a quarter turn (90 degrees) around its axis, the medium is passed or blocked.

They are characterized by a long service life and seal reliably over their entire service life, even if the valve has not been used for a long time. Stainless steel is used for corrosive media and harsh environments. Ball valves can be used both as shut-off valves and as control valves for liquids and gases. In control valves, the bore is usually V-shaped.
