JOEPAI High Quality Stainless Steel Wafer Flange Ball Valves are ultra-compact, quarter-turn shutoff valves sandwiched between standard pipe flanges. They are favored for tight spaces in industrial, chemical, and pharmaceutical pipelines. These heavy-duty, one-piece body valves offer excellent corrosion resistance and unrestricted, full-port fluid control.They are designed to be clamped directly between two pipeline flanges using long bolts that span the entire body length. By eliminating integrated end flanges, it achieves an ultra-short face-to-face dimension, making it significantly lighter and more affordable than standard flanged ball valves.
Compact Body:Ultra-thin one-piece construction minimizes pipeline footprint
Connection Mechanism:Installs between pipe flanges, secured by compression of flanking bolts
Low Hold-up Volume:Short distance between ball and outer edge reduces medium retention and dead zones
Materials:Carbon Steel (WCB / A105), Stainless Steel (CF8/304, CF8M/316)
Pressure Ratings:ASME Class 150 / 300, EN PN10 / PN16 / PN40
Seating Types:Soft-seated (PTFE / RTFE) for zero leakage
Bore Types:Full Port (maximum flow efficiency), V-Port / Segmented (precise throttling)
