Heavy
Duty Spherical Valves
Are
you tired of flimsy valves
that gum-up, jam or leak?
Do you need a valve that
is specifically designed
for dry material rather
than one designed for liquids
or gasses? Want to solve
a troublesome valve installation
once-and-for-all?
The Roto-Disc® company
has been making valves
and air-locks for
difficult dry and
slurry material handling
applications since
1984. Our unique
valve overcomes the
natural weaknesses
of other valve styles
and provides you
with a precision
engineered product
that will handle
even the most difficult
applications. With
thousands of valve
installations handling
hundreds of different
types of product,
you can trust that
Roto-Disc will solve
your valve problems.
Below are
some of the reasons
why…

Roto-Disc Valves
When All Else Fails |
|
|
-
Standard actuator is
a double acting vane-type.
Spring return, rack & pinion,
electric or hydraulic
actuators are also available,
as is a handle for manual
actuation.
-
Solenoid valves control
the actuator and can
cause the valve to fail
closed, fail open, or
fail last. Voltages can
be 12-24VDC or 110-240VAC.
Other controls can be
supplied for dribble-feed
or throttling.
-
Steel seat retainer
protects seat from exposure
to product.
-
Product contact surfaces
can be polished up to
a mirror finish. Teflon®,
stick-release and other
coatings are also available.

-
Position
Indicators with
visual beacon let
you and your control
system know the
position of the
valve.
-
Body & Dome
are manufactured
from heavy-duty
cast steel alloys,
aluminum or ductile
iron.
-
ANSI 150# flange
drilling (thru
holes) is standard.
Threaded, DIN PN10
or custom flange
drilling is also
available.

| Seat
replacement is a cinch
- just take off the
seat retainer and drop
in a new seat. No shaft
adjustments or alignment,
not coutner-rotating
bushings - NO HASTLE! |
Sticky,
gummy, abrasive substances,
powders, pellets, granules,
chips - almost anything
that runs through a
process line can be
handled by this valve. |
If
you can't afford to
spend time looking
for replacements or
have your valves out
of service for repair,
you need a Roto-Disc.
It could end your valve
headaches forever. |

|
|
|
| When
the Roto-Disc® is
open, the product
flow is completely
unobstructed and
the seat is protected
from direct contact
with the material. |
As
the Roto-Disc® begins
closing, the wiping
action of the rotating
dome smoothly cuts
off the flow of material
with no pinch points
or opportunity for
material to wedge
between the seat
and the dome. |
When
the Roto-Disc® is
closed, the dome
and the seat form
a positive seal that
virtually eliminates
leakage.
