Model Numbers:


The “L” Defines the Language: 

U = English (NFPA) 

E = English (CSA/ISO)

F = French (CSA/ISO) 

S = Spanish (NFPA)


The ”G” Defines the Gas:

O = Oxygen

A = Medical Air

V = MedVac

2 = Nitrous Oxide

N = Nitrogen

C = Carbon Dioxide



I = Instrument Air


Replace ”X” with the Required Valve Size:

1 = 1/2" [1.3 cm]      05

2 = 3/4" [1.9 cm]      07

3 = 1" [2.5 cm]         10

4 = 1-1/4" [3.2 cm]   12

5 = 1-1/2" [3.8 cm]   15

6 = 2" [5.1 cm]        20F




The power supply will require 1 gang per box. Example: English, 3 valves, 1/2" [1.3 cm] oxygen, 3/4" [1.9 cm] medical air and 1-1/4" [3.18 cm] medvac. Will be in a 4 gang box. AVU-1O2A4V


The 1-1/2" [3.8 cm] valve will have an empty space above the valve. Example: A box with a 1/2" [1.3 cm] oxygen, 3/4" [1.9 cm] medical air and a 1-1/2" [3.8 cm] medvac valves will require a 5 hole box not a 3 hole box.


The 2" [5.1 cm] valve will be assembled in a 6-1/2" [16.5 cm] deep box and shall accommodate up to a maximum of 4 gases. The 2" [5.1 cm] valve shall be positioned on the bottom of the assembly. Refer to 2" [5.1 cm] Valve Drawing provided on page 2.


The height measurements of the 6-1/2" [16.5 cm] valve box are the same as the 3-7/8" [9.84 cm] valve box. When comparing height measurements, consider the gap above the 2" [5.1 cm] valve.


Example: A valve box with 2" [5.1 cm], 1/2" [1.3 cm] and a power supply would be in a 3 gang 6-1/2" [16.5 cm] deep box, which would be the same height as the 4 gang 3-7/8" [9.84 cm] box.
