Rancilio Silvia Expansion/Over Pressure Valve (OPV) Rebuild Kit

$21.00

Rancilio Silvia expansion valve, also called over pressure valve (OPV) rebuilt kit.  This kit is for machines built after 2006 that include the adjustable OPV.  Kit includes the spring, a viton oring as well as the valve seat and gasket.

You will need to calibrate the OPV to open at 9 bars so you may want to consider purchasing a portafilter pressure gauge kit since the Silvia does not have a pressure gauge.

 

Rancilio part numbers 10060006, 39110040 and 36404039.

This kit is a good idea.

I decided to rebuild my OPV as part of a more general service on an older Silvia. When I disassembled the OPV I discovered it was calcified beyond belief. I decalcify often, but the OPV doesn't get done in the process. This is a reasonably easy job, but requires a 20mm spanner, and a thin one at that. I ended up removing the entire valve assembly from the boiler and soaking it in Dezcal.
