The Cast Steel Ball Valve (Precision Casting) is made by investment (lost-wax) casting, giving a dense, smooth body with accurate dimensions and fewer casting defects than sand casting. The floating ball design with PTFE seats provides fast quarter-turn operation and bubble-tight shut-off for small and medium sizes.
