High Performance PFA* Lining

• Melt processable for precise molding of parts with smoother surface finishes than PTFE liners.
• Superior flexibility to withstand repeated flexing and dynamic loads for extended service life.
• Higher resistance to permeation for increased durability with lower total cost of ownership.
• Lower particle shedding for maximum purity.
• Superior creep resistance at high temperatures.
• Increased resistance to microbial contamination.

*PFA is also known by the trade name Teflon®.

Acriseal^TM Stem Sealing System

Precision engineered for reliable, maintenance-free service, the Acriseal^TM three step stem sealing system provides unmatched sealing for long term zero leakage performance. The primary seal is created by the spherically molded PFA body liner and matching disc hub interface. The energized backup liner maintains tight contact pressure for consistent shutoff in high cycle applications. An independent secondary seal is formed by the extended body and disc liners. The flexible PFA body liner extends into the stem cavity and the disc liner envelops the stem. The resulting protective sleeve eliminates potential leak paths for fugitive emissions and shields internal components from contact with the media. This feature works in conjunction with the tertiary safety seal to ensure compliance with ISO 15848-1 standards for fugitive emissions.

The third sealing mechanism in the Acriseal^TM stem sealing system is a graphite filled PTFE safety seal. Completely isolated from the process media by the extended disc liner and energized by a coil spring, the safety seal self-adjusts for changes in temperature and wear to ensure absolute zero leakage shutoff of corrosive and ultra pure process media.
