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. The regulator will maintain a positive vessel pressure reducing the possibility of vessel wall collapse.
