Teflon Lined Ball Valve
Teflon Lined Ball Valve
The full port flow path increases the CV of PFA Lined Ball Valve and decreases pressure loss resulting in a more efficient piping system. The one piece ball and stem design of our PFA Lined Ball Valve results in higher pressure & temperature rating and reduces the potential of ball or stem failure. Our PFA Lined Ball Valve facilitates universal ISO 5211 mounting dimensions and its quarter turn design simplify valve Actuation.
Attributes :
- 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
- Live loading packing system provided by PTFE “V“Rings in the deep stuffing box and by the molded liner
- Antistatic device protects against potentially dangerous electrostatic discharges
- Labyrinth like seal with increased surface loading by means of molded 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 seat rings 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
