- Industry / Applications
Amresist is the leading manufacturer of high performance PFA lined butterfly valves in North America. AMRI’s Acris fully PFA lined valves have been trusted in demanding corrosive and ultra pure industrial applications for over 25 years.
Fully PFA lined butterfly valves engineered for bidirectional zero leakage shutoff in demanding corrosive and ultra pure industrial applications.
Acris PFA lined butterfly valves offer unsurpassed resistance to corrosion, permeation and microbial contamination for maximum purity and reliability with minimal maintenance. Engineered for bidirectional zero leakage shutoff, Acris fully PFA lined valves are the high performance solution for critical applications. Made in USA.
Fully PFA lined disc and body provide unsurpassed resistance to corrosion, permeation and microbial contamination for maximum purity and reliability with minimum maintenance.Durable, spherically molded PFA liner and matching disc interface to form a tight bidirectional seal.Full width 360° energized backup liner provides uniform sealing.AcrisealTM live-loaded, stem sealing system self-adjusts to eliminate leak paths and reduce fugitive emissions for long-term, maintenance-free operation. (ISO 15848-1 compliant)Extended PFA liner forms a protective sleeve shielding the stem from corrosive media and eliminating leak paths.PFA disc over-molding is mechanically bonded to the base metal for full vacuum capability.Streamlined disc engineered for maximum flow.High-strength one-piece 17-4 stainless steel disc and stem standard for improved reliability.Energized flange seals maintain proper sealing between valve and flange.
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®.
