General Information:
The Industrial Line of valves
provides the highest reliability even under the most demanding of
applications. the I21series piloted diaphragm valves do
require a minimum operating pressure, which allows them to operate
properly but offer a higher flow (Cv). These valves also
provide a bubble-tight shutoff and work well with gasses, fluids,
light oils and other clean flowing media.

Any Position (best if vertical and
upright)
