Hello everyone, I am from Asia and I have been a fan of this forum. Recently, I have started to try DIY projects. As English is not my native language, I am using GTP for translation. :D :D

I will try my best to describe text using images. :P

I think new users have to be manually approved and therefore there might be a delay between post date and the day it is actually visible.

Welcome to the forum and excellent work! Are you using commercially available airgun parts? I've noticed there are quite a few valve units, regulators and tanks available on eBay.

Yes, around 2013, I purchased valve components, but I didn't have time to complete the project as I was still in high school.

Main valves and CO2 fire extinguisher valves have similar functions, and their stems can also be interchangeable.

Last year, I found these valve devices again in the trash bin. Although the rubber O-rings were damaged, I restored the airtightness by using 3D printing with TPU.

I came across some potential designs on other forums that utilize soda canisters and fire extinguisher valves. I'm really excited to work on the next design using these readily available valves.
