Product Description
The Type ACE95jr tank blanketing valve is an
extension of the Type ACE95 tank blanketing valve
and is intended to handle lesser flows on gas
blanketing systems. The valve 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. The Type ACE95jr maintains a slightly positive
pressure and thereby reduces the possibility of tank
wall collapse during pump out operations.
