I had read they were drained before shipping if its shipped by air.

Hmm if that is the case, the seller didn't add a note saying that the gauge was drained

[redtrucker610]

I remember reading that from one of the sellers on Aliexpress. I don't think it was stated from the seller I purchased from.

The 6000 psi check valve arrived today and I installed it between the black and gold filters after adding quick disconnects on both ends. I then proceeded to top off one of my SCBA tanks. The valve worked just as I had hoped. I was able to purge the compressor without having to shut off the SCBA valve. This makes filling the tanks just as easy as filling a gun directly.

Well I bought some glycerin today and filled the gauge. It help dampen the needle but I'm afraid now since the needle will not Zero it is not accurate enough. This one will get me by until the new gauge comes in

[gendoc]

what do you guys know about this one ?
it says 220 60hz. & to use #46 hydraulic oil.

i will not be filling any tanks, just for topping off rifles.

Robert, sounds good. What is the part number and where did you purchase your check valve. Bob

Here's the 6000 psi stainless steel check valve that I ordered: http://www.discovervalve.com/INCVSS01.html
It was $26.90 including shipping. You will also need 1/8" NPT quick disconnects for each end unless you plan to connect it with threaded connections.

Don't know about that style compressor. I have the yong heng compressor 110 volt

Do you have a pic of what it looks like. I'm not understanding what it is supposed to do?

Robert, thanks. I just placed an order for two for each end of the large filter. Bob

Why do you want one for each end of the filter?

[shultz]

Ken,

Roberts check valve will trap the air in the high side filter, hose and air tank when water bleeds are being done.

It will also eliminate the need to close the tank valve when doing water bleeds.

Great idea.

[Bob Pratl]

My goal was to hold pressure in the large filter after a refill, but after giving it some thought a check valve on the out put won't work, so I think that I will add a needle valve together with a bleeder on the output that will allow the filter to stay pressurized to save time for the next refill. I will add the check valve on the input side of the filter as you suggested. I found that it takes quite a few minutes to fill up the empty filter. Bob

Without a picture I'm guessing you have the same as what I've got coming in the mail from AIR TANKS PLUS. 

One each of

and screw them together.  Just remember to orient them the right direction, which doesn't take a rocket scientist to accomplish.

You definitely need some way to depressurize the filter when you want to open it up to change the filter media.
BTW, I just eliminated the QD on the output side of the valve (input side of the filter) and screwed the valve directly into the filter.

[elguapo99]

Here's a couple of pics of the check valve setup. The check valve is the stainless steel piece that is in between the black filter and the gold filter. The input side of the valve is depressurized with the bleed valve on the compressor and the output side is depressurized with the bleed valve on the fill station. This setup works for filling tanks but is not needed for filling guns because the gun already has a check valve built-in.

[kzz1kaw]

Ok thanks for the picture and explanation makes more sense now😎

[gendoc]

where can you get the gold and black filters ?

[elguapo99]

The black filter comes with the Yong Heng compressor. The gold filter can be purchased on aliexpress: https://www.aliexpress.com/item/This-is-a-gift-free-of-mechanical-parts-the-link-is-used-for-customers-pay-the/32602913439.html?spm=2114.13010608.0.0.0pHKMp
