PTFE Lined Butterfly Valve | Full PTFE Lining, Corrosion Resistant

Name: Reguvale PTFE Lined Butterfly Valve
Brand: Reguvale
Availability: InStock

PTFE Lined Butterfly Valve — Full Chemical Resistance

Full PTFE Body Lining · PTFE Seat · Acids · Alkalis · Aggressive Chemicals

Reguvale’s PTFE lined butterfly valve has the body interior fully lined with PTFE (Teflon) plus a PTFE seat, giving near-universal chemical resistance for corrosive acids, alkalis, solvents and aggressive media.

Ideal for chemical processing, dosing and transfer lines, pickling plants, wastewater treatment and any service where rubber seats would be destroyed. The PTFE lining protects the ductile iron body while the PTFE seat provides bubble-tight shutoff.

Body materials: ductile iron GGG50 with full PTFE lining. Seat: PTFE. Flanged ends per EN 1092 / ASME B16.5. Available with manual lever, gear, pneumatic or electric actuation.

DN50–DN600 PN10/PN16 Full PTFE Lining -200°C to +200°C Bubble-Tight

Frequently Asked Questions

What is a PTFE lined butterfly valve?

A PTFE lined butterfly valve has the body interior fully lined with PTFE (Teflon) and a PTFE seat, giving near-universal chemical resistance for corrosive acids, alkalis and aggressive media.

What chemicals can it handle?

PTFE resists nearly all acids, alkalis, solvents and aggressive chemicals across a wide temperature range, making it ideal for chemical processing, dosing and transfer lines.

What temperature range does PTFE lining handle?

PTFE lined butterfly valves typically operate from -200°C to +200°C, covering most chemical processing applications.

How is PTFE lining different from a PTFE seat only?

A fully lined valve protects the entire body interior from corrosion, not just the sealing surface. This matters for aggressive media that contact the body wall.
