Key benefit: High flow, quick response
Case study
Requirement
Emergency, clinical and ICU ventilators need
to be reliable and comfortable for all patients –
neonatal, infant and adult. There is increasing
competition to make them portable as well.
OEMs needed a dosing and mixing valve
with high flow rates, quick response time,
and good controllability. They also wanted
a smaller, lighter valve that consumed less
energy. Long service life was important
as well.
Solution
The unique IMI FAS FLATPROP EQI and EQP
miniature proportional valves have frictionless
flat springs and plungers for response times
below 10 milliseconds and high flow rates of
110 liters per minute for the FLATPROP EQI
and 186 liters per minute for the FLATPROP
EQP at 2 bar oxygen. Both have excellent
mixing and dosing accuracy. Compared with
competing valves, at just 11 cubic centimeters
and 40 grams, these valves are one-quarter
the size and weight use only 25 percent of the
energy required so users get lower operating
costs and longer batter life in portable
equipment.
