Y690A Series Tank Blanketing Valve
The Y690A Series Gas Blanketing Regulator System reduces a high-pressure gas, such as nitrogen, to maintain a protective environment above any liquid stored in a tank or vessel. The regulator system replaces the volume of vapors with a volume of blanketing gas to prevent the internal vessel pressure from decreasing, when liquid is being pumped out or when the vessel is suddenly cooled, causing vapors to contract. In both cases a slight positive vessel pressure prevents outside, air, moisture and other contaminants from entering the vessel. The Type Y690A is a direct-operated regulator used for accurate pressure control on very low pressure blanketing systems. Downstream pressure is sensed through a pitot tube installed in the lower casing of the regulator, thus no external control line is required. The Type Y690AM uses a control line to more accurately control the pressure if the regulator is mounted away from the tank.

Type Y692 Tank Blanketing Valve

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.

66 Series Pressure Reducing Regulators
The Type 66 self-operated regulator maintains a reduced outlet pressure while satisfying the downstream flow demands.  The Type 66Z and 66ZZ self-operated regulators also control a reduced outlet pressure; however, both have springs sensitive to negative pressures and can be used for vacuum regulation.  Each regulator type has a balancing diaphragm which increases accurate and sensitive response to pressure changes by reducing the unbalanced forces acting on the valve plug.
