Absolutely fantastic mod & super informative video. Many thanks for your content. Can I ask do you have a video showing how to add the manometer to the portafilter 🤔👍👍👍
Not this modification is certainly not more convenient :) But ordering these springs from the UK costs the same as the OPV in Poland on the spot, so most want me to put them on an OPV.
@@jamesmac6102 Not every time but sometimes. I first adjust the pressure to 9bar as others did. I found that it' s not my taste and set it to 8 bar, still not word. I tried many times till I found t8.4 is the sweet pot for me. With a spring, you probably never find it out.
@@Goingtothedogpark It doesn't make any sense. You've removed the workings of an over pressure valve and replaced them with another over pressure valve. You believe (probably cos you've seen similar utube vids) by doing so you are reducing the pressure, which in a way you are but only by diverting the flow. A much better way to divert the flow would be to introduce an adjustable flow diverter valve on the other line which diverts excsess flow back through the pump therefore leaving the over pressure valve untouched and set to do it's job which is to protect the pump in scenarios of over pressurization. The OPV is not designed to have continuous flow.
On the piston you removed does the blunt flat side or the narrow side face the spring on the stock setup? I've been told the blunt side toward the spring but it looks like it came out the opposite way. I'm having some issues with pressure on the stock setup.
You have a link to the valve in the description, it is an opv valve from Ascaso. I know that my English is tragic :) I try to say what Google translates me :)
Originally it is the same ??? I don't know where you got this information but it's not the same. Gaggia originally has a set of 13 bar, it is the pressure under the perfect crema sieve and if you want to use low pressure sieves you have to make a modification using a spring or install an OPV valve. Every day I modify Gaggia coffee machines and I know what I am writing. Here's an example when I tested a customer's coffee machine on the original valve that Gaggia assembles ua-cam.com/video/qnaTAbPR_0k/v-deo.html So the simplest modification is the spring or if you want to play with different pressures then the adjustable OPV valve ua-cam.com/video/jQQKu4wIStk/v-deo.html

Hello, great video. Not sure if this mod is more convenient then change springs, but still good that we have it.

the spring can only offer one pressure, the opv provides much more pressure options.
@@darrenz2636 Are you changing the pressure each time you are using the machine? lol You should set it to 9 bar for good.

@@darrenz2636 Even James Hoffmann will not be able to distinguish between 9 to 8.4bars...
Bad idea to have the tube resting on the boiler?
Okay and You didn't know that... :)
I’ve read your website. please dont ever take it down. it like a guidebook for the new DIY like us! amazing details & works!
Why don't Gaggia just set the Over Pressure Valve to 9 bar ??
It's because of the pod and pressurized baskets for folks who don't want to grind. It makes big difference.

@@seantivenan9593 I didn't do this mod. I did the 9 bar spring mod which is super easy. Also comes with 6 bar.in kit.
@@seantivenan9593 Have you figured out a way to do this? I would like to learn more

Great video! Just what I was hoping to do-have adjustable OPV, rather than swapping in different springs. Thanks!
Great video I always attended for your videos. They are amazing and great tku so much from merida yucatan Mexico.
Yes, the Over Pressure Valve Valve
so cool. !
Hej! Czy jest rysunek tego zaworu?
Nie nie ma rysunku tego zaworka
Cześć, można gdzieś dostać sprężynę 9bar w polskiej dystrybucji?
Nie wiem ??
@@Gaggia_Fixer bo właśnie zastanawiam się nad tym jak zmienić na 9 bar bo z tym zaworem bez manometru ciężko chyba będzie "wystroić" maszynę 🤔

@@jonsss44 Nie da się, kupujesz sprężynę lub zawór i ustawiasz na manometr.
@@Gaggia_Fixer o ile zawór na allegro widzę to manometra za huhu nie mogę znaleźć 🙁
Do you have link where to buy the 2 opv parts? No pun intended but i had trouble understanding your English.

Hi. Why change one for the other if it is the same?
The original valve is perfectly adjustable and has the same principle of operation.

Not in the new Gaggia Classic Pro, you have only a not adjustable spring valve there.
