General Information:
The Industrial Line of valves
provides the highest reliability even under the most demanding of
applications. the I81series zero-differential valves do not
require the minimum operating pressure the I21 series does.
This allows them to operate from a "zero" inlet pressure to the
stated maximum operating pressure differential (MOPD). 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)
