The Anderson Greenwood / Crosby Type 9700 is designed for emergency vent applications and combines the simplicity of a weight-loaded device with the performance of a pilot operated pressure relief valve. The design, built on Anderson Greenwood / Crosby’s 25 years of experience in low pressure safety relief valves, offers several significant and unique advantages over traditional weight-loaded vents. The 9700 is specially designed for emergency vent applications and combines the simplicity of a weight-loaded device with performance levels comparable to that of POPRVs. The 9700 is ideally suited for toxic/corrosive storage tank applications with liquids such as hydrochloric acid, methylene chloride, ethylene dichloride or phosphorus trichloride.

Tank Blanketing Regulators
Tank Blanketing provides an inert gas blanket over the liquid in a liquid storage tank. The Anderson Greenwood / Crosby Trans-Zero Regulator is a pilot operated, dome-loaded diaphragm type regulator capable of reducing blanketing gas from 14 barg to 12.5 mm wc in a single step providing bubble-tight shut off and low maintenance costs.
