 Many
municipal water plants that produce water
for your local community have pneumatic
control valves that operate the water back
flush system. Typically, these valve systems
are made by Versa Products and are usually
on individual manifolds. There is also an
older system manufactured by BIF that is
convertible to the Versa system. These
valves were installed years ago with many
cycles on them and are by-passing both
internally and externally. Once confronted
with this application, we begin to apply our
“Imagineering” to the requirement at hand.
We have designed a retrofit manifold that
incorporates the same valves that were
originally on the equipment with the
addition of an updated manifold mounting
option and air diaphragm spool actuators.
These manifolds control the water flow
valving used for back flushing the water
filters. The manifold incorporates valves
with common inlet and exhaust ports. It
eliminates many connection ports and allows
the valves to be changed with no disturbance
to the piping. The pictures are working
manifolds that went into a north Alabama
water plant in 2008 and are installed and
running.
 Theses
systems are entirely pneumatically operated
manually. If during the upgrade process a
filter plant wanted to automate the process
more we can add electrical controls via
field bus that can offer remote access via
the internet. This technology allows control
of this block (outputs), other blocks and
(inputs) to communicate with a programmable
controller with one wire. This means that
you can add additional items and or monitor
numerous readings of pressure, flow,
temperature, cameras, thermostats and even
security checkpoints with one wire connected
to a PLC. All this information can be logged
and uploaded to any authorized user.
Finally, the person or persons responsible
for the functionality of entire system can
control and monitor the system from home or
office over the internet. If you are
interested in a review of your plant and a
feasibility study or just need the valves
replaced with our new manifold design,
e-mail rhydrick@flowdynamics.net with your
requirement.
Also shown is a computer
controlled water modulation valve with
infinitely variable position/flow according
to an input reference signal. This new
design is capable to dealing with pure water
and high pressure up to 3000 psi.
