Product Name
Manual Vacuum Ball Valve, 316 Stainless – Two-Piece, ISO-K Flange (ISO80 / ISO100)
Product Summary
A two-piece 316 stainless manual vacuum ball valve with an ISO-K vacuum flange (ISO80 / ISO100),
lever handle, PTFE seats, and high-tightness vacuum seals.
The YZNG TRONG manual vacuum ball valve isolates or connects vacuum lines by hand where
automation is not needed. The lever handle gives a fast, positive quarter-turn open and close, while
the two-piece 316 stainless body, PTFE seats, and high-tightness vacuum seals keep leakage low in
coating, drying, degassing, and food-processing lines.
Connection
The valve uses an ISO-K vacuum flange (ISO80 / ISO100), so it clamps straight into standard ISO-K
vacuum lines without an adapter.
