This ACE95 Series valve was assembled and preset to

the customer specified pressure and set point. The

outlet pressure range of the valve is stamped on the

nameplate fastened to the upper actuator case. The gas

blanketing set point is the only adjustable feature on

this unit.

1. Use qualified personnel when installing, operating,

and maintaining valves. Before installing, inspect the

valve and tubing for any shipment damage or foreign

material that may have collected. Make certain the

body interior is clean and the pipelines are free of

foreign material. Apply pipe compound only to the male

pipe threads with a screwed body, or use suitable line

gaskets and good bolting practices with a flanged body.

2. Inspect the nameplate on the upper actuator case.

It displays the model number, serial number, a blanket-

ing gas supply pressure range, and the maximum inlet

pressure and set pressure. These must agree with the

system that you are blanketing. The serial number will

be needed in any communication with your Fisher Sales

Representative or the Fisher Sales Office.

3. Clean the gas blanketing supply lines of all dirt and

foreign material before connecting them to the ACE95

Series tank blanketing valve.

line to tank.
