Frequently Ask Questions

What Is a PTFE Wafer Type Butterfly Valve?

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

What Is the Advantage of Wafer Construction?

The wafer design provides a compact and lightweight valve arrangement that can be installed between compatible pipeline flanges without integral flanges on the valve body.

Why Is PTFE Lining Used?

PTFE provides excellent chemical resistance against many acids, alkalis, solvents and aggressive process chemicals, protecting the underlying valve body from direct contact with the media.

Who Is a PTFE Wafer Type Butterfly Valve Manufacturer in India?

Alis Valves manufactures and supplies PTFE-lined Wafer Type Butterfly Valves for chemical processing, pharmaceutical, fertilizer, water treatment, petrochemical and other corrosive industrial applications.
