EHA replaced all the existing hydraulic valve system and manifolds in a Feed Mill with
new explosion proof valves and custom manifolds. These valves are used to
operate the augers that feed material to the scales prior to mixing the final
product.

EHA scheduled the project with an electrical company to install the valves over
three weekends so as not to interrupt the customer's operation. EHA installed one
bank of valves on each Saturday while the electricians came in to finish the wiring
on Sunday.

Every Feed Mill or Coop should be using explosion proof valving for
both their hydraulic and pneumatic applications. In this case Dynex valves were
used.
