A specially patented Ball Valve having PTFE / PFA Lining directly moulded on all surfaces having contact with   the fluid. The thickness of the lining is calculated to ensure total protection against highly corrosive chemicals   for long service life.

Unlike conventional Ball Valves the ball assembly is consisting of one solid piece without any looseness so that   there is no deterioration of lining in the area of Ball Seam Welding. The Thickness of the lining is absolutely   constant throughout to avoid any deformation of the ball.
