Rocket Expansion Valve (OPV)

Took a chance swapping this in and the over-pressure valve does exactly what it should—my shots are much more consistent now. Installation was straightforward with basic tools, and the water flow feels perfectly regulated. A solid upgrade for anyone wanting better extraction stability.

Finally got consistent pressure after months of fiddling with my old valve. This genuine OPV part was a perfect fit and installed in about 15 minutes. The water pressure regulation is now spot on for my shots.

Installed this to replace a temperamental stock part on my machine. The pressure regulation during extraction feels much more stable now, which my shots definitely appreciate.
