The Type 1190 low pressure gas blanketing valve is a pilot-operated, pressure reducing valve with a supply pressure regulator. This valve is used for extremely accurate pressure control on very low pressure gas blanketing systems. The Type 1190 helps to control emissions and provides protection against any contamination from atmospheric conditions by providing a flushing action.

The Type 1190 gas blanketing valve maintains a positive vessel pressure thereby reducing the possibility of vessel wall collapse during pumpout operations.
