The spring assembly includes at least two springs with ladder-shaped longitudinal sections that are reverse-superimposed. Ball ValvesThe inside of first sealing element fits well with the surface of said valve ball, while its outside functions as a supporting surface and an acting surface for said spring assembly.BALL VALVES The resulting configuration provides a ball valve with a desirable sealing effect.
