Hi-tech Polymers supplies Polytetrafluoroethylene - PTFE Lined Ball Valve. Hi-tech Polymers manufactures PTFE components for petrochemicals, refineries, fertilizers, power, marine, aerospace industries etc. Polytetrafluoroethylene - PTFE Lined Ball Valve is directly molded on all surfaces having contact with the fluid. The thickness of the lining of Polytetrafluoroethylene - PTFE Lined Ball Valve 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 of this valve is absolutely constant throughout to avoid any deformation of the ball.
