Jkhan valves

[oneshot61]

Does anyone know if the valves in the .22, .25 and 357 are the same? And are they just restricting power through port size and valve and hammer spring rates? Thanks!

I don't think they are the same for every size. For example my .35 Noblesse bullpup valve has a throat size of about 8.6mm or  0.34". I believe that's the size used in atleast some of the .45 Evanix models. Although my Noblesse is a special edition one with long unchoked barrel so it may have a bigger valve than the regular .35 Jkhans. Unfortunately the seller has no interest telling about the details of the gun, so I can't be sure.

I have taken it apart and I have the pictures to prove it. I'm planning to post them at some point when I find time to do it.

Thank you. I have a schematic but it doesn't give details. I wonder if those valves can be ordered from someone? Looking forward to your pics.

Hi
You might want to contact Randy at R&L airguns about the valve.
He maybe able to help you out or at least answer your questions
Hope this helps

So... I called rl airguns back today and they said that the valves are all different in each caliber..., and they cannot get any. So I'm wondering if they are using the same valves as the evanix rifles? Anybody know?

It is quite probable that the valves are the same as those guns share many of their parts. However, before investing in Evanix valve you might want to read this http://www.gatewaytoairguns.org/GTA/index.php?topic=102270.0

Thank you for the response. That's unfortunate. I hope they address that issue in their new valves as that is the heart of the gun. I haven't heard any bad news yet on the Jkhan valves but people are starting to mod them so time will tell. Any custom valve makers that you know of?

No, but any competent air gun tuner should be able to make you one. They are not that hard to DIY either if you have basic tools and a bench drill.

Thank you, I'll check around. My gun shoots fine, but I have a project in mind.

Here's a couple of pictures of my .357 noblesse valve. The design seems to be same as Evanix, but the dimensions seem to have some variation.

The valve stems look identical from the picture perspective.
