The Accu-Pressure Type Y692 gas blanketing regulator is a pressure reducing self-operated regulator with internal registration requiring no downstream control line. It is used for accurate pressure control on very low pressure blanketing systems. Blanketing with low pressure gas helps prevent corrosion, helps control emissions from the blanketed product and helps protect against any contamination to the blanketed product by atmospheric conditions.
The regulator will maintain a positive vessel pressure reducing the possibility of vessel wall collapse. The Type Y692 is available in 1-1/2 or 2-inch (DN 40 or 50) body sizes.
