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. Type Y692 is available in NPS 1-1/2 or 2 / DN 40 or 50 body sizes.
