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 NPS 1-1/2 or 2 (DN 40 or 50) body sizes.
