Choosing the right valve lining is essential for process efficiency. PTFE-lined and rubber-lined butterfly valves serve different purposes depending on application needs.
Chemical Compatibility
-
PTFE Lining: Resistant to nearly all chemicals
-
Rubber Lining: Limited resistance, unsuitable for aggressive media
Temperature Handling
-
PTFE valves perform well at higher temperatures
-
Rubber linings degrade under heat exposure
Service Life
PTFE Butterfly Valves offer:
-
Longer lifespan
-
Minimal wear
-
Reduced replacement cycles
Maintenance Requirements
PTFE surfaces resist scaling and chemical attack, resulting in lower maintenance compared to rubber-lined valves.
Cost Consideration
Rubber-lined valves may be economical initially, but PTFE valves offer superior long-term value.
Conclusion
For demanding applications involving corrosive or high-purity fluids, PTFE Butterfly Valves outperform rubber-lined alternatives.
