Bulletin 74.1:ACE95 Specifications The Specifications section lists the specifications for Types ACE95 and ACE95Sr Tank Blanketing Valves. Factory specification is stamped on the nameplate fastened on the valve at the factory.
Bulletin 74.1:ACE95 Introduction • Control Pressure Gauge—Low-pressure gauge to measure control pressure (tank pressure). Tank blanketing is the process of using a gas, such as nitrogen, to maintain a slightly positive pressure in an enclosed storage tank. Tank blanketing prevents a stored product from vaporizing into the atmosphere, reduces product combustibility and prevents oxidation or contamination of the product by reducing its exposure to air.

Bulletin 74.1:ACE95 Diagnostics Thermal Equations Tank blanketing valves are often installed in locations that are difficult to access. Types ACE95 and ACE95Sr valves are available with a diagnostics feature that allows analysis of valve operation in the field, making maintenance easier and more reliable.
