Fisher Type Y692 Low-Pressure Gas Blanketing Regulator

The Accu-Pressure™ Type Y692 Gas Blanketing Regulator is a pressure reducing direct operated regulator with internal registration or external pressure registration. 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 and 2 / DN 40 and 50 body sizes. Type Y692 with external pressure registration regulators have a stem seal with O-rings and a 1/2 NPT control line connection in the diaphragm case. The control line can be used to more accurately control the pressure in the tank if the regulator is mounted an extended distance from the control point. The stem seal separates the body outlet pressure from the diaphragm case.
