Product Description
The Type 1190 low-pressure gas blanketing regulator
is a pilot-operated, pressure reducing regulator with
a supply pressure regulator. This regulator is used
for extremely accurate pressure control on very
low-pressure gas blanketing systems. This regulator
helps to control emissions and provides protection
against any contamination from atmospheric
conditions by providing a flushing action.
The Type 1190 gas blanketing regulator maintains a
positive vessel pressure thereby reducing the possibility
of vessel wall collapse during pump-out operations.
