What Does “WA125” Mean on My AqMatic Valve?

If you’ve noticed WA125 printed on your AQ Matic valve, you might wonder what it means. This marking is not the part number or model number. Instead, it tells you two key details about your valve:

• WA stands for Water or Air, indicating the type of application.
• 125 refers to the pressure rating (125 PSI).

So, while “WA125” gives useful information about the valve’s capabilities, it’s not the identifying number you’ll need for ordering parts or finding replacement valves.

How to Identify Your AQ Matic Valve

To find the correct part number for your AQ Matic valve, look for the metal tag attached to the valve body. This tag provides the official AqMatic part number, which is essential when ordering replacement valves, repair kits, or solenoid parts.

If your valve’s metal tag is missing, damaged, or unreadable, don’t worry—our team at Buy AqMatic is here to help. Simply email or text clear photos of your valve, and we’ll identify it for you quickly and accurately.

So what do you actually need to order parts?

WA125 tells you the valve’s service rating, not which valve you have. To find parts or a replacement, you need to work out three things.

First, what is the valve made of?

Second, if it is cast iron, is it on liquid or air?

Liquid service is a V42. Air service is a VAV.

Third, what is the pipe size?

Three ways to get there:

• Measure it: 3/4 inch, 2 inch, and so on
• Read the model code, such as V42B or V42H
• Read the valve sub-number on the K series, such as K521 or K524
