There are a variety of hydraulic components on the La San Marco 95 espresso machine. This ranges from pressure gauges, copper tubing, flowmeter, over pressure valves (OPV) and water inlet valves.
What kind of components there are used on the San Marco 95 espresso machine depends on various factors. You need to think of how many brewing groups does my machine have and do I have a normal, Sprint or a Practical version or a S or E model. Seen all these models require different components.
What does a S or E model mean? Well the E model is the volumetric version and the S version is the non volumetric model. On the volumetric model you will find a flowmeter and with the S model not.
