What is a PTFE Lined Stainless Steel Butterfly Valve?

A PTFE lined stainless steel butterfly valve typically features:

• Stainless steel or cast steel body

• PTFE lining on wetted surfaces

• Excellent corrosion resistance

• Reliable sealing performance

The valve operates by rotating the disc 90° to:

• Open or shut off flow quickly

• Regulate flow rate

• Safely isolate pipeline systems

The PTFE lining prevents direct contact between aggressive chemicals and the valve body, protecting the equipment and extending service life.

Why Choose a PTFE Lined Stainless Steel Butterfly Valve?
