Non-Rising Stem Manual Flanged Knife Gate Valve (DN50–DN2000, 10–16 bar, WCB/SS) | DELCO

DELCO Non-Rising Stem Manual Flanged Knife Gate Valve is built for on/off isolation in slurry, wastewater, pulp, and other solids-laden services. The knife gate provides a cutting shut-off action to reduce clogging at closure. It covers DN50–DN2000 with a 10–16 bar pressure range, and is available in WCB or stainless steel body materials. The non-rising stem handwheel design saves installation height, while flanged ends ensure stable pipeline connection.
