Regulator input psi question

I purchased a 3,000psi reg for a bottle gun but noticed there are 4,000psi regs that look exactly the same. What do they do internally that makes them handle or regulate more input pressure? I have a 300 bar gun and this reg is really killing my shot count. I guess I can always just buy one and take a look inside but I figured I would ask first.
 
Why would you want to put an 3000 or 4000 psi reg in your gun? Mind as well not put a reg if you're going that high. The point of the reg is so you get constant pressure when you fill to 3000-3500psi. Example your reg is set to 1900 psi, and your fill pressure is 3000. Your valve will only see 1900 psi till your tank pressure drops below 1900. A 3000-4000 psi reg will not benefit you in any way. A reg have different size bevel washers and thickness. Usually thicker washers will handle higher pressure. But there is a limit to how high or how low it can go. Read your reg manual so you dont damage it by screwing it too much.

Those are not 3000 and 4500 psi reg. Those are its maximum fill pressure. Fill pressure and reg pressure are totally different things. You see where it says 1.8k on the burst disc? So its reg pressure is well below 1800 psi. If reg pressure gets above 1800 psi the birst disc will blow. Those look like ninja paintball tank valves. So its reg pressure is like 800 to 1100 psi max. Those valves aren't 3000 and 4500 psi reg. Also know that even if the valve says 4500 psi, most tank is rated to 3000 psi. So beware and know what you are doing. You do not want to put a 4500 psi valve on a 3000 psi bottle and fill you 4500 psi just cause the valve says 4500 psi. The tank itself has to be rated for 4500 psi also. Hpa isnt something you wanna mess with if you dont know what you are doing. It's a bomb waiting to go off.

I have a 300b bottle on my gun and with the factory reg I always filled to 275b. The factory reg has issues with a floating set point which the manufacturer is aware of and is working to rectify. In the meantime I bought one of this style regs from JDS airman to tide me over. With this reg I have only been filling to 200b because the 3,000psi INPUT model was the only one available with metric threads. JDS sells a 4,500 but it doesn’t have metric bottle threads otherwise I would have bought it. Just wondering what makes one capable of 300b. I have my output set at 150b. That’s where I liked my factory reg when it would stay there. I am not building bombs, just curious. I have Huma regs in guns that range from 200b to 300b fill pressure. Never noticed anything different except some had a tiny grub screw in the set point screw.

I was just curious if internally maybe they used a different spool or something to handle the higher input/bottle pressure. It is pushing back against another 1,000psi as it reaches its setpoint. Maybe the spool and washer stacks in these regs have a really broad range. I just always let an "add to cart" through Huma fix all my reg woes. This gun has forced me to truly try to understand regulators. This reg was not very impressive out of the box but after some polishing and surfacing, it is shockingly good. I am just giving up 100b worth of shots because I cant fill to what my bottle is capable of.

Good afternoon

I have 2 Air Venturi 90 cubic inch bottles rated at 4500psi.

I generally fill to 4000 to allow a safety margin

Both bottles have output Air Venturi Valves

The output on the valves is fixed at 2900psi

My question are

  • Are there valves that will fit these bottles that have a higher fixed output pressure?
  • Are there unregulated out put valves that will fit the bottles

I'd like to get to 3600 psi if possible.

Thanks

Ed

You might try adding a extra set of bellvilles or doubling some up ,that is a fair jump in pressure.

A kot of the ninjas came out 100 psi low ,then you could add a couple spacers to grt to 3000

I just brought a chinese reg in and it tested over 550 psi low,was supposed to be 4500 in 3000 out,output was 2450 ,kelly

Thanks, Kelly

I'd prefer not to disassemble, add, rearrange,or double up, the bellville washers & reassemble.

Concerns go to

- fixing something that's not broken;

- and needing reassurance that washer mod would be safe.



Are there any regulators out there that re 4500 in & 3000 or higher out put
