VIBRA-GATE™
Duplex Valve
The VIBRA-GATE™ duplex valve is ideal for
discharging almost any granular material from a
bin or hopper where the materials are difficult to
discharge. The VIBRA-GATE duplex valve easily
handles sticky, cohesive, high moisture and
difficult to handle materials such as green foundry
molding sand. It has the ability of utilizing vibration
in a unique way to discharge and dislodge most
materials from a bin or hopper with a high degree
of control. Materials thought to be very difficult
to discharge are more easily moved and nicely
controlled with predictable results. The VIBRA-GATE
duplex valve can even be used like a feeder to
control the feed rate of a given material when trying
to fill a container such as filling a foundry flask to a
predetermined level. With the VIBRA-GATE duplex
valve, there will be little need for any other flow aid
devices to get your stored material moving upon
demand and without flushing.
The VIBRA-GATE duplex valve by design creates
the ultimate vibrating force required to discharge
material which otherwise might tend to hang up
from a bin or hopper. This special vibrating force is
then efficiently transmitted to a bin or hopper in a
unique way for optimum results. The vibrating force
is created by the rapid opening and closing of a
pair of clam shell gates against four large shock
absorbing bumpers, which in turn vibrates the bin
or hopper walls. In addition, by simply adjusting
the door opening width and frequency, the natural
vibrating force can be increased or decreased as
might be desired. Even tough materials become
easy to control and feed.
The VIBRA-GATE duplex valve is available in
various sizes to suit almost any specific application,
and is available with any type of control as might
be desired, including hand or foot control devices.
Optional materials of construction and propriety
coatings are available upon request.
