How does E61 flow control work?
This flow control device adjusts the flow of water through a needle valve which controls the pressure applied by the pump on the grouphead , thereby controlling the quantity of water that flows through your espresso.
What does E61 mean on espresso machine?
E61 is the name of an espresso machine brought to market in 1961 by the Italian company Faema. This machine brought in a new era of espresso makers. Not only was the E61 the first heat exchanger machine, meaning that fresh water was used for making espresso instead of boiler water.
What is an E61 group head?

What is a flow control device?
The flow control device is designed with an integral orifice to give a predetermined optimum flow rate and air intake to the interceptor The orifice openings are related to the size and flow rating of the GCD.
Who invented E61?
Invented by Ernesto Valente in 1961, the E61 introduced many more innovations and espresso firsts. Rather than relying on the manual force of the barista, it used a motorized pump to provides the nine atmospheric bars of pressure needed for brewing espresso.

Do I need flow control?
Why are flow control valves needed? In many cases when an HVAC system is put into place it will require an exact amount of constant flow in order to properly size pumps, piping and other accessories Without proper flow control valves in place, fluctuating system pressures will deviate from design flow.
How important is flow control espresso?
Flow control is all about controlling the flow rate of water during pre-infusion and during extraction as water passes through the coffee puck. By controlling the flow rate of water, you have the ability to bring out all of the nuances of your coffee.
What is a good flow rate for espresso?
Flow Rate And Flow Profiling The flow rate of an espresso machine is a measurement of how much water passes through the grouphead while the pump is active. Most commercial machines have a flow rate of between 250 and 500 grams per 30 seconds (g/30s), but the ideal range is between 200 and 280 g/30s.
What is the purpose of a bottomless portafilter?
Bottomless portafilters allow the barista to instantly deduce whether proper tamping technique has been achieved If the extraction leans to one side or the other an improper angle was used when tamping.
What is a Grouphead?
Essentially, the group head is the part of the espresso machine where water from the boiler is dispensed into the coffee filter basket It acts as a meeting point, connecting the machine to the group handle and the water to coffee.
How does an espresso Grouphead work?
The group head is a part of any espresso machine. It is the heart of the machine and responsible for creating a great cup of espresso. Located on the front of the machine, the group head is a metal, permanent attachment that brings water out of the machine and into the filter basket.
Which is better double boiler or heat exchanger?
A two group, dual boiler machine can effectively double your capacity With this type of machine you could have two baristas brewing and steaming at once, solving speed issues you might be experiencing. They are also more precise than heat exchangers because of the dedicated boiler.
Why is my group head leaking?
If the grouphead leaks from the space in between the portafilter and the grouphead during brewing then the group gasket is either worn out or out of place This gasket needs to be replaced typically every six months to a year. Use a flathead screwdriver to pull the shower screen down and off the machine.
Is Flow Control same pressure profiling?
Pressure doesn’t come into play until after the basket fills. Then we get into pressure profiling, which also affects the flow rate. This was always my TLDR for this. Flow profiling is all about what happens before the head-space reaches positive pressurization.
Is Profitec same as ECM?
The Profitec 700 is almost identical to the ECM , but some of the fit and finish is not quite up to the same standards. The Rocket uses different internals, such a smaller set of brass boilers instead of the stainless steel ones on the ECM.
Does pressure affect extraction?
The Impact of Pump Pressure However, pump pressure affects the contact time the coffee has with the water, thereby affecting the overall extraction Changing the pressure of your pump also directly influences the water delivery rate from the group head. Turn the pressure up and the millilitres per second increases.
What does the flow control valve do?
A very common function of flow control valves is to control the speed of cylinders and air motors The speed of cylinders or air motors depends on the amount of air, which can be controlled by flow control valves.
What does a flow regulator do?
For one, a flow regulator typically involves controlling the flow-rate of water in various applications These regulators usually respond to other devices in the system like a temperature gauge or flow meter. On the other hand, pressure regulators are mainly used in gas and air applications.
What does the flow control valve to propane?
Although other gas valves may be present throughout the gas plumbing, the service valve, on the propane tank, is the valve that controls 100% of the gas flow into the gas system Basically, propane service valves function as the “on / off switch” in propane gas systems and is for vapor service only.
Is Gaggia owned by Philips?
Yes, that’s right – Gaggia was purchased by Saeco in 1999; Saeco was then purchased by Dutch-based electronics manufacturer Philips in 2009 With both Saeco and Gaggia now being owned by the same company, it’s to be expected that there are a lot of similarities between the two brands.
Where are Gaggia machines made?

How long should an espresso take to pour?
The best shots of espresso are pulled in a range within 25-30 seconds from when then pump starts, with espresso dropping from the portafilter after 5-7 seconds.
What does double boiler mean in a coffee machine?
It’s a dual-use boiler , so you either brew your espresso first and then wait for the machine to heat up to steaming temperature, or steam your milk first and cool down the boiler to brewing temperature. With a heat exchange or dual boiler machine you can brew and steam at the same time.
Is the Breville Barista Pro dual boiler?

Is 58mm portafilter better than 54mm?
Let’s see what the main distinctions with the traditional 58mm portafilter are. During extraction with a 9 bar pressure, the 54mm portafilter weighs about 30kg less on the coffee cake compared to the 58mm With the same dose of coffee, the 54mm portafilter ensures a taller coffee cake.
Do all portafilters fit?
The compatibility of portafilters between brands sometimes becomes an issue. Most manufacturers make their own versions and even those of the same diameter sometimes do not fit those of other makes This holds especially true in the lower priced entry levels and in the upper end dual boilers.
What is temp surfing?
Temperature surfing is a process of getting your espresso machine close to your target brewing temp Generally, people use a coffee maker or a stove to brew coffee with hot water (or sometimes they even brew their coffee with milk).

This technique must be done daily with water alone, but at least once a week you should back flush with cleaner such as Puly Caff. To use the cleaner, simply place a tea spoon full on top of the blind filter before back-flushing. Run the group in 10 second intervals several times.
What is a brew unit?
The brewing unit is a hydraulic and mechanical system that collects a capsule on its open position, seals the capsule inside a brewing chamber, allows water to flow through the capsule and goes back to the initial position to expel the capsule.
