PTFE Lined Butterfly Valve Manufacturer: FlowBiz Exports
The FlowBiz Lined Butterfly Valve is a high-performance flow control solution specifically built for services involving reactive chemicals, acids, and alkalis. By lining the entire internal wetted body and the disc (flapper) with fluoropolymers like PFA or FEP, we ensure that the metallic components are completely shielded from corrosion, providing a cost-effective alternative to expensive exotic alloy valves.

Rigorous Testing Standards
Safety and integrity are our priorities. Every valve undergoes a three-stage testing process:
- Hydrostatic Test: $11\text{ kg/cm}^2$ to Full Vacuum (as per BS/API).
- Pneumatic Test: $7\text{ kg/cm}^2$ for air-tightness.
- Spark Test: 15 KVA DC to ensure the lining is free from pinholes or defects.
Key Features & Advantages
- Compact Two-Piece Design: Manufactured as per BSEN and API standards for easy installation and space efficiency.
- 100% Tight Shut-Off: Provides bidirectional, bubble-tight sealing across all pressure ranges.
- Easy Torque Operation: Both shafts are mounted in bearing supports, ensuring smooth rotation and reduced manual or automated effort.
- Gasket-Free Installation: The molded lining acts as a flange gasket, eliminating the need for additional jointing materials during installation.
- Full Flow Control: Optimized for both high-cycle on/off service and moderate throttling in quarter-turn ($90^{\circ}$) operations.
