Type 90 Miniature Precision
Air Pressure Regulator
Accurate pressure regulation in a compact, lightweight package
The Type 90 is a miniature precision air pressure regulator. This
pressure regulator provides the highest level of regulation accuracy
and repeatability available in a compact, lightweight housing. A
force balanced pilot control maintains output pressure to within 0.05
psig (3.44 millibar) with minimal drift over time. The Type 90 is ideal
for applications that require exact pressure control and substantial
flow capacity under variable operating conditions and limited space.
