For decades
Clyde Bergemann Delta Ducon has
been supplying rotary valves to handle extremely
abrasive materials. PERMA/flo eXTreme rotary
airlocks are considered the valve of choice by many
customers who demand long life and high quality. The
basic design of the "XL" has remained unchanged
since 1964. Until now...

At this time, CBDD is
pleased to introduce the PERMA/flo eXTreme "XT" rotary valve. The new "XT"
is based on
the time proven concept of the "XL".
The
major enhancement of the "XT" is the increased
throat dimension on the 6" through 12" models. The
increased throat provides up to an additional 82%
over the existing "XL" design. This was
achieved by
increasing the number of pockets in the rotor from
nine to ten. This in turn allows the inlet shoe to
widen, exposing a two-pocket width in lieu of one.
This extra width minimizes possible bridging while
increasing pocket fill efficiency. Sizes 14" through
24" shall remain our traditional “XL” design.

The "XL" and “XT” series, can
be applied as rotary feeders and airlocks. Both the
“XL” and "XT" series of rotary valves feature a
unique design that offers adjustment between the
rotor and the seal shoe. This adjustability enables
the rotor to seal shoe gap to be maintained
providing the tightest seal possible through out the
life of the unit.
Both the rotor and seal shoe
are constructed of a special chrome-iron alloy
called P-33. This alloy yields a hardness of 500-600 Brinell. Unlike other valves that feature a surface
hardening, P-33 is a solid alloy casting that does
not wear off to expose a softer metal base. |
