PFA/FEP Butterfly Valves
PFA/FEP Lined Butterfly Valves offer excellent corrosion resistance for handling aggressive chemicals, ensuring tight shutoff and smooth flow control in chemical process systems.
Overview
Product Overview
PFA/FEP Lined Butterfly Valves are engineered for use in highly corrosive applications where metal valves fail due to chemical attack. These valves are internally lined with PFA or FEP fluoropolymer material, offering excellent resistance to acids, alkalis, solvents, and other aggressive media.
The valve’s disc is fully encapsulated with PFA/FEP to prevent contact between the process fluid and metal parts. Their compact, lightweight design and bubble-tight sealing make them ideal for flow control and on/off applications in industries like chemicals, pharmaceuticals, and water treatment.
Available in wafer and lug-type designs, these valves can be operated manually or with pneumatic/electric actuators.
For selection, evaluate flow rate, discharge pressure or head, viscosity, temperature, solids content, material compatibility, and installation conditions. Sando Rotary supports industrial buyers with application-led recommendations for valves procurement.

Selection Guide
Lined vs. Metal Valves
Selection Point 1
Choose lined valves when the process fluid is corrosive and must be isolated from the metal body.
Selection Point 2
Choose metal valves when temperature, pressure, abrasion, or mechanical strength is the main driver.
Selection Point 3
Correct selection depends on chemical compatibility, pressure class, temperature, and actuation needs.
