Constant speed valve
Hi all, I I am wondering if anyone has any information about a “constant speed valve” offered on Amazon for the Condor and Talon by a company called Hfire. I have been unable to find any information aside from 1 post I found here. Has anyone tried one of these? It appears as though it has a secondary air chamber which may regulate pressure from the tank. Also looks like the “top hat” has some very large passages. Sure looks nice too! Thanks for any info.

It’s P.O.S. is what I know
maw, 20Mpa=2900psi. Do both gauges read the same? I think the intermediate cylinder should be the shooting pressure you want regardless of pressure in the main tank. If pressure in the main tank drops below the intermediate cylinder then pressure should be the same.
3000 was the end of the green at 20
Hi Maw, what do the gauges read? How much pressure did you use for charge?
Oh, I don’t like Mpa. PSI is much more familiar. Seems the gauges should be physically larger to accurately measure Mpa.
I have mine set where you se the tread coming out , like 1 thread backed out.
Yes, the nut or screw on the end does regulate pressure to the intermediate tank and allow filling of the main tank. I just removed the valve and backed this ‘nut’ out a little and now the other gauge is working and there is air pressure showing in the main tank. I’ll have to use a hand pump beyond this as my scuba tank is only at 1500psi. There seems to be far too few threads on this adjusting ‘nut.’ I’ll post with further results.
I just wasted alot of air screwing around with this thing and am not happy with the reg yet, it started raining and getting late, so not done yet, I plan on carring on tomarrow, butt so far I could not get more then 37,98 ft. pounds, shooting 22’s, 25 grn.
Update!!
OK, I have just dry fired my Condor 4 times and emptied the tank which means my ‘fill’ only filled the ‘intermediate’ chamber and did not introduce any air to the main tank which explains the fact that the other gauge did not register anything. I will later remove the valve and try to adjust the pressure regulating nut. This is BS! Why couldn’t the manufacturer have at least a rudimentary instruction sheet? Thanks all-lets get to the bottom of this.
Glad someone else got one besides me! Mine arrived yesterday. I was able to install but not test yet. No instructions as stated already. One of the gauges shows pressure after tank fill but the other does not. Air leaked overnight. I tried firing without pellet and it worked. Does not work with Talon Tunes angle adapter as it bottoms out before making contact with oring. I read something on the Amazon reviews about adjusting pressure with the brass piece on the portion (the diagram calls this piece the’pressure regulating copper nut) of the valve that screws into the factory air tank which means exhausting air from tank, removing valve, adjusting copper nut, filling, and testing. This is gonna be fun! I am happy to have a few more working on this. Please post any finds.
got the valve today, no, none, nothing, for instructions to change the pressure of the reg. anyone got one know how??? I read someone said it was easy.
Bought one still waiting for delivery, not sure I got the right one cause they had different valve opening sizes.
It’s a valve with pressure regulator. Made in China: http://www.aliexpress.com/wholesale?SearchText=valve+pcp&catId=&initiative_id=SB_20140810020758
Interesting!
