Your expert guide to selecting the right Fluoropolymer Lined Butterfly Valve. From standard PTFE to high-pressure RPTFE and high-performance PFA options, handle aggressive media with the unmatched quality of JRVAL's manufacturing.
PTFE (Polytetrafluoroethylene) liners offer a unique combination of properties that make them the superior choice for demanding applications. PTFE is widely known by the brand name Teflon™, a registered trademark of The Chemours Company. We can supply valves with genuine Teflon™ materials upon request.
PTFE is virtually immune to all chemicals, including strong acids, bases, solvents, and chlorides, preventing liner degradation and ensuring long service life.
The smooth, non-porous surface of PTFE prevents media buildup and contamination, making it ideal for food & beverage, pharmaceutical, and semiconductor applications.
PTFE has one of the lowest coefficients of friction of any solid, reducing operating torque. This allows for smaller, more cost-effective actuators and smoother operation.
PTFE lined valves can handle a broad spectrum of temperatures, typically from -29°C to 200°C (-20°F to 400°F), making them suitable for both cold service and hot chemical processes.
Lug-style valves feature threaded inserts, allowing them to be bolted to one flange for dead-end service. This design is crucial for applications where downstream piping may be disconnected for maintenance under upstream pressure.
The base valve assembly for automation, providing maximum corrosion resistance and guaranteed dimensional accuracy from a zero-porosity casting.
