 Type ACE95jr Tank Blanketing Valve

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.
