KF80 GI Manual High Vacuum Butterfly Valve, 304 Stainless Steel, ISO-KF Interface, KF-80 NW-80 Vacuum Fittings

GI‑type manual high vacuum butterfly valves are widely deployed in industrial processes and research facilities.
Valves are nearly as critical to vacuum systems as vacuum pumps.

Applications: Primarily for on-off control and connection of vacuum pipelines.
Widely used in universities, laboratories and research institutes.

Note: When fully open, the valve disc extends out of the valve body and may interfere with the inner wall of the mating pipe.
Verify the minimum inner diameter (ID) of the connecting pipe prior to installation.

Interface: Standard ISO / NW / KF 80
Sealing material: FKM/ Viton Ring
