View Data Sheet (94270 Vapor Guard Tank Blanketing Valve)
Product in Tank
*
The stored liquid or material inside the tank.
How to determine?
Refer to process description, inventory records, or Safety Data Sheet (SDS).
1 - Units, Choose barrels or gallons
*
This selects the appropriate conversion factors for sizing the valve.
Barrels
Gallons
How to determine?
Look at your industry standard reporting.
2 - What is the Pump Out Rate?
*
Maximum rate at which product can be withdrawn from the tank.
Untitled
*
U.S. Gallons per Min
U.S. Gallons per Hour
U.S. Barrels per Hour
U.S. Barrels per Day
How to determine?
Check pump specifications or process flow diagrams.
3 - Inert Gas Supply Pressure
Pressure range available from the inert gas source, usually controlled by a regulator.
How to determine?
Confirm regulator settings, supply header pressure, or gas system specifications.
Minimum PSI
*
Maximum PSI
*
4 - What is the Mounting Position of N2 Valve?
Whether the valve is mounted horizontally in pipe or vertically on tank nozzle.
How to determine?
Confirm with tank installation drawings or piping layout.
Horizontal in Pipe
*
Yes
No
Vertical on Tank Nozzle
*
Yes
No
5 - Valve Body Materials of Construction?
*
Material specification for the valve body, such as carbon steel, stainless steel, or alloy.
How to determine?
Match with stored product requirements; check tank material specs and process compatibility.
Valve Soft Goods Material of Construction?
Material specification for the seals, seats, and gaskets used inside the valve.
How to determine?
Review compatibility against the product’s Safety Data Sheet (SDS) and chemical resistance charts.
6 - What is the Connection Size
*
Size of the nozzle or pipe connection for the valve.
How to determine?
Measure tank nozzle size or piping spec.
7 - Is Sense Line Connection on Tank Available in 1/4"?
*
Indicates whether a ¼″ sensing connection is available.
Yes
No
How to determine?
Check nozzle list or tank drawings.
8 - What is the Tank Design Pressure?
*
Maximum internal pressure the tank can safely handle.
How to determine?
Refer to tank spec sheet or nameplate.
What is the Tank Design Vacuum?
*
The maximum vacuum condition the tank can safely withstand.
How to determine?
Refer to design drawings or manufacturer’s specs.
9 - What is the Tank Operating Pressure?
*
Normal working pressure during operations.
How to determine?
Review process conditions or pressure logs.
10 - What is the N2 Valve Set Pressure?
*
Pressure setting where the blanketing valve opens.
How to determine?
Typically set slightly above operating pressure, below design pressure.
11 - Pressure/Vacuum Vent (Existing on Tank)?
*
Identifies if a P/V vent is installed, and its set point.
Yes
No
How to determine?
Check vent nameplate or vent sizing sheet.
If YES; What is the Pressure Set Point?
*
We suggest you complete the P/V Application Sheet on our website so that we can recommend the appropriate size.
