 Tank blanketing valves must 

be installed, operated and maintained 

in accordance with federal, state and 

local codes, rules and regulations 

and Emerson Process Management 

regulator Technologies, Inc. 

(Emerson™) instructions.
If the valve vents gas or a leak develops 

in the system, service to the unit may be 

required. Failure to correct trouble could 

result in a hazardous condition.
Installation, operation and maintenance 

procedures performed by unqualified 

personnel may result in improper 

adjustment and unsafe operation. Either 

condition may result in equipment 

damage or personal injury. Use qualified 

personnel when installing, operating 

and maintaining the Type ACE95jr Tank 

Blanketing Valve.

Scope of the Manual

This Instruction Manual provides installation, startup 

and maintenance procedures for the Type ACE95jr 

tank blanketing valve. See Figure 1.

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.
