Description
PTFE Lined Ball Valve Manufacturer & Exporter in India
FlowBiz PTFE/PFA Lined Ball Valves are engineered specifically for full-bore, zero-leakage shut-off in pipelines carrying highly corrosive chemicals, strong acids, and hazardous solvents. Constructed with a heavy-duty cast steel or ductile iron body fully lined with thick, high-density fluoropolymer, these valves isolate structural metal components from aggressive line media, delivering a long-lasting, cost-effective alternative to exotic alloy valves (such as Hastelloy or Titanium).
Core Performance Features & Corrosion-Resistant Design
- Seamless Fluoropolymer Lined Cavity: The inner body chamber and ball are encapsulated with virgin PTFE or PFA (minimum 3mm to 5mm thickness), ensuring total chemical inertness against harsh acids and alkalis.
- Full-Bore Hydrodynamic Flow: Precision-molded full-port ball geometry allows unimpeded fluid transfer, minimizing pressure drop, turbulence, and fluid entrapment across process lines.
- Dovetail Mechanical Anchor: PFA/PTFE linings are mechanically locked into the metal casing via precision dovetail grooves, preventing liner collapse or separation under high-vacuum and thermal cycling conditions.
- Blowout-Proof Stem Sealing: Integrated lower-entry stem assembly with live-loaded PTFE chevron V-ring packing prevents stem displacement and eliminates fugitive emissions.
