Flowgrid
|
The Flowgrid Valve was designed
to fill the need for an easy-to-maintain valve that would be used primarily
with self-contained pilot systems for both liquid and gas applications. As a
self-contained, pilot-operated device, it can offer substantial energy
savings when compared to conventional air-operated or electrically operated
control valves
