FAQ
What media is suitable for a PTFE lined butterfly valve?
This valve is ideal for corrosive chemicals, acids, alkalis, and ultra-pure fluids.
Can this butterfly valve be used for vacuum applications?
Yes, PTFE-lined butterfly valves are often suitable for low-pressure vacuum systems depending on the design.
What is the difference between PN0.6 and PN1.6MPa in butterfly valves?
The PN rating indicates pressure tolerance. PN1.6MPa handles higher pressures than PN0.6MPa.
Is the valve bidirectional or unidirectional?
This valve supports bidirectional flow due to its center disc design.
How do I choose between lever and gear-operated models?
Use lever operation for smaller sizes (DN40–DN150) and gear operation for larger valves or higher torque needs.
