Finally added this to my V1 (7/00) Silvia. Original OPV was measured with a portafilter gauge at 11bar. The new OPV was installed and measured at 9 bar. Huge difference pulling shots, well worth it and I wish I did this years ago. If you do upgrade your V1 get the new stainless braided hose and 90 degree elbow and use Teflon tape on threads (OPV, hose to elbow, elbow to pump).

My stock opv on 2000 Silvia was allowing 13 bar. Swapped with this whack came set at 9 bar. Big difference in the cup. You probably will need the compression fitting if you do not want to reuse the original.

This part saved the day for me, and Espresso Parts got it to me very quickly. One thing that the web site doesn't show or state is that the part comes with a set of copper washers that are absolutely necessary to get the proper alignment of the part in relation to the boiler.

Replaced the original OPV in my 6/2000 Silvia. Much improved performance. Easy to install. Very fast service from Espresso Parts.

Quick and easy replacement. As stated, does not come with compression fitting nut - I reused the existing one with no problem. I don't have a portafilter pressure gauge to test, but using the timed flow test I get 9 bar on the button. Espresso tastes great and that's the true test

I had read several reviews that the newer OPV was better so I intended to replace mine. Unfortunately I could not install this valve as the original (2003) would not come off. It appeared that all the parts were there though.
