Excellent Corrosion Resistance

Full PTFE lining provides outstanding resistance against strong acids, alkalis, solvents, and other aggressive chemicals, extending valve service life in harsh environments.

Superior Chemical Compatibility

PTFE material offers wide chemical resistance and prevents contamination, making it ideal for chemical processing, pharmaceutical, and high-purity applications.

Low Friction & Smooth Operation

The low-friction PTFE liner reduces operating torque and ensures smooth opening and closing with minimal wear.

Reliable Bubble-Tight Shut-Off

Resilient PTFE seat design provides tight sealing performance with low leakage rates for dependable isolation service.

Protection Between Media and Valve Body

The PTFE liner creates a complete barrier between corrosive fluids and metal components, reducing corrosion damage and maintenance requirements.

Lightweight & Cost-Effective Design

Compared with fully corrosion-resistant alloy valves, PTFE lined butterfly valves provide a more economical solution while maintaining excellent corrosion protection.

Suitable for Aggressive Media Handling

Designed for challenging applications involving chemicals, acids, chlorine, solvents, and other corrosive fluids.

Easy Maintenance & Long Service Life

Simple butterfly valve structure combined with durable PTFE lining helps reduce downtime and lowers total operating costs.
