Fisher Type 1190 Low-Pressure Gas Blanketing Regulator
Rp123000.00
The Fisher Type 1190 is a pilot-operated low-pressure gas blanketing regulator, designed specifically to maintain a precise and positive pressure inside storage tanks. This unit is ideal for applications requiring extremely low and accurate outlet pressures, such as inert gas blanketing of storage vessels containing volatile liquids. It prevents atmospheric contamination and vessel collapse by ensuring a constant pressure blanket. The system includes the Type 1098-EGR main valve actuator, Type T205P sensing pilot, and Type MR95H supply pressure regulator for reliable performance.
