Fully PFA lined butterfly valves engineered for bidirectional bubble-tight shutoff in demanding corrosive, chemical, semiconductor, and ultrapure water applications. SIL 3 certified and fully PFA lined for corrosive media and demanding applications. Reliable shutoff solution for industrial and chemical processes.
Size range: 2" to 24", DN 50 to 600. Maximum allowable operating pressure: 2" to 6" up to 16 bar, and from 8" to 24" up to 10 bar. Body materials in ductile iron. Disc stem materials: 2" to 12" 17-4 stainless steel over-molded with PFA and 14" a 24" 17-4 stainless steel stem/high strength steel disc over-molded with PFA. Temperature range: -29ºC to +160ºC. Flange drilling: ASME B16.5 CL150 | ASME B16.1 CL125 | PN10, 16 | JIS 10K. Also available in Wafer.
A. Fully PFA lined disc and body: proprietary compound provides unsurpassed resistance to corrosion, permeation, and microbial contamination for maximum purity and reliability with minimum maintenance.
B. Durable, spherically molded PFA liner and matching disc: interface forms a tight bidirectional seal.
C. Full width 360º seat energizer: ensures uniform sealing.
D. Live-loaded, stem sealing system: self-adjusts to eliminate leak paths and reduce fugitive emissions for long-term, maintenance-free operation. (Standard sealing system meets ISO 15848-1 low fugitive emission requirements.)
E. Extended PFA shaft over-molding: enhances stem sealing, eliminates leak paths, and shields the stem from corrosive media.
F. PFA disc over-molding: PFA resin is mechanically bonded to the base metal to enable vacuum capability.
G. Streamlined disc: engineered for maximum flow.
H. High-strength, one piece 17-4 stainless steel disc and stem: standard for improved reliability.
I. Energized flange seal: maintains proper sealing between valve and flange.
J. Mechanically retained seat energizer: wide elastomer seat energizer rests in a machined body groove to enable end-of-line service at full working pressure.
