Hello!
Wonderful upgrade, but I don't have a pressure gauge, so I'm having some trouble finding 9.5 bars.
I was wondering how low does the pressure go and how high, so I can "aim" the screw? :)
Thanks in advance!

Hi Blaer, I understand that it is adjustable to 9-10 bars. Fitting the OPV reduces pump pressure from 16 bar to 10 bars.

Hello! Has this valve been successfully used in a Breville Barista Express machine? Could it work to replace the stock OPV and reduce the output pressure?

Hi Javier, I don't know, we would only get this feedback from reviews. Usually, it will reduce by 1-2 bars maximum. See this link from a Reddit user who has success with this OPV

Do these come pre-lubed with silicone grease applied at the spring/plunger?

Hi Mihir, They don't come with lubrication, inside is a spring and grommet - the o ring keeps it tight and from getting loose over time. Lubrication is unnecessary.

Hello
I need a Opv for my nuova sim. Oscar 2- Can I use this one?

Hi Simon, One of our customers successfully installed this OPV on a Nuova Simonelli Oscar I - so probably will fit - but cannot confirm.

Hello, is there a way with this OPV to get 11 bar pressure? Is there a tension spring inside that can be replaced? Thanks!

Hi Frederic, You can replace the spring,by unscrewing the screw anticlockwise. We don't have other springs, other than what comes with this.

Hey,
I would like to install this kit in my isomac giada, but there's not enough room to fit it onto my pump. I want to put a pipe in between the pump and the opv. What fitting should i use to mount the pipe on the opv? for the pump i have an elbow fitting, but the opv has thread...

Hi Jim, this takes a 1/8" fitting - we have a list of recommended fittings on the page.
