Victor EDGE 2 0 Pressure Flow Hybrid Regulator for Brazing, Nitrogen Purge and Pressure Testing

- A conversation between Victor and an HVAC professional and CTE instructor on the value of nitrogen purging and the newest development from Victor.
Designed for three common HVAC applications - brazing, purging and pressure testing - the EDGE™ 2.0 ESS32 PFH800 combines flow and pressure regulation functions in a single device. The new regulator provides adjustability between:
1. 3 - 6 CFH for using nitrogen as a backing gas when brazing
2. 20 - 50 CFH for nitrogen purge applications
3. 200 - 800 psi to conduct pressure tests
Traditionally, a regulator would either be a flow regulation device or a pressure delivery regulation device. To create a wide range of adjustability, Victor designed a new, patent-pending dual-stage gas flow orifice. The first stage orifice enables lower flow rates. When the flow rate applies sufficient backpressure, it pushes open the first stage orifice poppet, which then allows gas flow to bypass the smaller first stage orifice and flow through a larger, second stage orifice at higher flow rates and pressures.

in the 3 videos you have done a spectacular job of not showcasing the product of showing hands on what it looks like and how it works.
Thank you for your feedback Jared.
So you're telling me I don't have to attach a flow meter to my regulator anymore?? That is friggin' sweet! Nice compact design fellas!
Hi here, I just picked up this regulator at a local supply house here in jersey. Love your product, there's only one thing, why does it take so long to pressurize the system during a pressure test? I am aware of the dual stage orifice, thought maybe I''m doing something wrong. it took me about 25 minutes to pressurize a residential 3 ton 410a system at 250 psi
If this is true, which I have heard similar on other regulator with these same features, then there needs to be a built in bypass for the high pressure/test use.
Personally, if I find this to be the case, then going back to my individual pieces will be more beneficial.
Yeah I noticed that an i haven't found anything to say otherwise so looks like back to using the old way lol
There is a third port on these that are plugged, replace the plug with a 1/4 flare service port, boom full flow testing.
@@Reloadeez I saw that port. So before I buy the part to do this wanted to confirm this works. You have done it? Thanks
The port is full flow, meaning it bypasses the regulator. You can put a high pressure Schrader valve on it and meter it in with main tank valve, or put a small inline regulator on the port that will limit the pressure coming out. I use a high pressure Schrader valve, meter in with tank valve and get pressure readings with gauges.
This regulator doesn’t get the attention it deserves! Yet!
I just bought one today. I like the features but was confused on the np out and the hp out on the brass side. I think I can bypass this by adding another port on the hp side on the brass body. What do you think?
@@jonaustin8343 Drill and tap at your own risk but why buy a regulator that isn't what you want when they've been a solved problem since the SR series (cheap rebuilt which means effectively new).
Hello . I got a nitrogen regulator the same brand edge victor . but the proplem is it look like cloged . Maybe not cloged because release presure but i cant reach to presure test a unit 550. What do yu think? does need clean smth or need to repair smth. Can you give me same idea. Thanks
It's 410A not A410, there is a difference, including sounding like a person that does not know what they are talking about. Essentially a sales person with no clue of their product.
Also, there is a need for those higher pressures, 300-600 psi for checking ductless systems. Manufacturers require them for proper install procedures.
Also, while he is correct most leaks can be located at lower pressures, higher pressure testing should be done. If your system is normally operating at 400psi and you don't test there and it fails during operation how does that abide by his point of doing it right for his company and the customer?
Nitrogen doesn't absorb water. Its inert. It entrains water and allows water liquid to easily vaporize , but doesn't absorb.
NITROGEN IS NOT INERT.
So an R410a split heat pump system that may operate at 35 bar (507psi) should only be pressure tested at 10 bar (150psi)? Yes right, because that will find a leak that is only apparent at 150 psi and below, not one that is only apparent at 450 psi. The pipe lines on a mini split and the fan coil should be strength pressure tested at as high a presssure as 41.0bar (600psi) for 15 minutes and then left at between 1 to 1.3 times the working pressure for a recommended 24 hours. So that could be 33.0bar (478psi) or more. The misinformation on the internet is truly amazing.
News Flash, Nitrogen does not absorb or hold moisture… it is ignore one another at parties and they certainly don’t shake hands
I had purchased this nitrogen pressure regulator but the high is not going more than 200 Psi. What should I do.

What's the difference between purging and brazing with nitrogen?
Brazing is the correct term for oxifuel welding OFW, purging is the process to release what is in the tube system so it won't corrode or other stuff.
Purging is getting all the gases out of the lines which will create carbon build up on the inside of your joints and piping. Nitrogen is a Inert gas which is not flammable like oxygen. Most don’t understand you need to purge all the natural atmospheric gases out. If you do not purge you will waste your time brazing.
@@jonaustin8343 thanks brother!
Algún día
Hope i find you r
Here in Brasil.
Testing gas lines at 150psi is crazy and ridiculous. 15psi for 15 mins nothing more. And this guys been in the race for 30 years, yikes!
You sir have a lot of leaks and most likely are in a attic most of your time
Depends on city code, where I live its 60 for 60, 60 psi for 60 minutes no decay. The city 20 miles to the west is 150 psi for 15 minutes no decay.
