Description
PTFE Lined Butterfly Valve Manufacturer & Exporter in India
FlowBiz PTFE Lined Butterfly Valves are high-integrity, quarter-turn flow control valves engineered specifically for zero-leakage isolation and throttling of highly corrosive chemicals, strong acids, and aggressive solvents. Featuring a heavy-duty fluoropolymer body lining and a fully encapsulated disc, these valves isolate metal components entirely from process fluids, offering a compact, lightweight, and cost-effective alternative to bulky lined gate or plug valves.
Key Performance Features & Quarter-Turn Design
- Total Fluoropolymer Isolation: The internal body cavity and disc shaft are completely encapsulated in virgin PTFE or PFA, ensuring zero contact between metallic components and corrosive line media.
- Resilient Elastomeric Backing: A resilient silicone or EPDM energizer pad behind the PTFE body liner maintains continuous circumferential pressure against the disc edge, delivering 100% bubble-tight shut-off.
- Low Torque & Compact Footprint: Precision-machined disc profiles and self-lubricating PTFE liners deliver smooth quarter-turn actuation with lower torque requirements, making them ideal for automated skid packages.
- One-Piece Disc & Shaft Assembly: Heavy-duty integrated shaft-disc construction eliminates internal pins or fasteners, preventing stress points and fluid entrapment in high-purity applications.
