Knife Gate Valve for Abrasive Media
Stafsjö’s knife gate valve RKO is reliable and particularly well suited for demanding reject and other abrasive media. The valve’s circular inlet and square outlet together with the gate, that has a rectangular shape and a bevel edge, counteracts clogging and blockages, which often is a problem in combination with junk traps, coarse reject and cleaners.
