Frequently Ask Questions

What Is a PTFE Double Flanged Butterfly Valve?

It is a double-flanged butterfly valve with PTFE-lined wetted surfaces, designed primarily for isolation and flow control of corrosive and chemically aggressive fluids.

What Is the Difference Between PTFE and PFA/FEP Lining?

PTFE, PFA and FEP are fluoropolymer materials with excellent chemical resistance. PFA and FEP can be selected where their particular processing and temperature characteristics provide an advantage. Alis Valves offers PFA/FEP/PTFE lining options in its lined-valve range.

What Is the Advantage of Double-Flanged Construction?

The double-flanged body provides a rigid and secure connection to the pipeline, making it particularly suitable for industrial piping systems and larger valve sizes.
