Roto-Disc® Company has
been manufacturing heavy duty
industrial valves for difficult
dry and slurry material handling
applications since 1984. The
spherical valves will slice through
almost any sticky, gummy or abrasive
substance and won’t
leak, gum-up or pinch/break product.
They are ideal for the
food, pharmaceutical and chemical
industries and as replacements
for ball, slide-gate / knife-gate,
and butterfly valves. Sanitary,
bubble-tight and diverter styles
are also available. Almost anything
that runs through a process line
can run through these workhorse
valves. Recently, Roto-Disc announces ISO 9001 compliance. Download the ISO 9001:2008 certificate.
