PTFE Lined 2 Piece Design Ball Valve
Salient Features
• Meet design specification as per B 16.34 / Face to Face as per ANSI B 16.10 / Flange dimensions as per B 16.5.
• Testing Standard as per BS - EN 12266 - 1 / DIN – EN - 588 - 1
• Lining Standard as per ASTM F 1545
• A two – piece Full port PFA lined ball valve which offers high safety factor, high stability, rigidity and eliminates a potential leakage path.
• A Ball to stop or start the flow of fluid.
• Full port flow path increases the CV of the valve and decreases pressure loss resulting in a more efficient piping system.
• One piece ball and stem design resulting in higher pressure & temperature rating and reducing the potential of ball or stem failure.
• Universal ISO 5211 mounting dimensions and quarter turn design simplify valve Actuation.
• Live loading packing system provided by PTFE “V” Rings in the deep stuffing box and by the moulded liner.
• Antistatic device protects against against potentially dangerous electrostatic discharges.
• Labyrinth like seal with increased surface loading by means of moulded sealing lips
• Full lining thickness in the sealing groove provides security against permeating media
• Fish – Hook groove anchoring lining suitable to vacuum application
• PTFE Cushion seatrings and easily replaceable
• Tight even during frequent cycles of hot and cold effected by almost metal to metal flange contact in the circumference area close to the
flange media.
• The body piece position themselves properly by means of the cup and cone shapes of each piece.
• Epoxy coated body and stainless steel hardware provide minimum atmospheric corrosion protection.
• As an alternative to valves made of exotic special metals.
