Rancilio Silvia OPV Rebuild Kit 2

Rancilio Silvia OPV Rebuild Kit for the Adjustable Valve

This kit is to rebuild the NEWER-Style Valve Adjustable OPV that has the lock nut (as shown in this link). This version of the Over Pressure Valve is found on machines built since +/- 2006 (machines produced around 2006 could have ether style). If you do not know which version you have. please refer to the above link.

For a kit to rebuild the older non-adjustable valve see this link.

NOTE: This valve will need to be calibrated to open at around 9 bar. As there is no gauge on a Silvia, you will need a way to test the pressure, such as this 1245401 portafilter-mounted test gauge (fits on the 3/8 BSP fitting where the spout attaches to the portafilter body.
