Solenoid valves for fully automatic coffee machines: Easy installation and quick maintenance

In close cooperation with leading manufacturers of fully automatic coffee machines, Bürkert has developed its new solenoid valve series. From the very beginning, the life cycle and level of service of the fully automatic machines and the valve have been paramount in the new development. This allowed the experience gained from the installation, operation and service of machine manufacturers to be incorporated into the development of the new solenoid valves. In addition to the technical data, great attention was therefore paid to optimal installation and safe maintenance during operation. The new valve series is set apart by its trend-setting service concept.

Challenges for solenoid valves in fully automatic coffee machines

Easy maintenance and quick service of

fully automatic coffee machines In coffee shop chains, coffee machines run 365 days a year. To ensure that the service and availability of fully automatic coffee machines can also be guaranteed in countries with different levels of education, maintenance must be carried out safely, easily and without tools. Any outage in service equates to reduced revenue.

The desire for ever more compact fully automatic coffee machines

The trend is increasingly favouring smaller and more compact fully automatic coffee machines with more functionalities. The solenoid valves used must therefore be smaller and more powerful.

High media compatibility and material resistance are required

Water is also a critical medium for every fully automatic machine, as everything ranging from tap water containing chlorine to aggressive osmosis water and well water rich in lime or minerals might be used. Moreover, temperatures up to 95°C are normal process conditions. The cleaning cycles are also being added to the fully automatic coffee machines.

The compact and service-friendly solenoid valve series

power supply units, rising ambient temperatures and the selection of suitable materials for global food approvals are the basis of our new valve series. You get added value from the completely hassle-free installation of solenoid valves in fully automatic production and tool-free service from core to diaphragm exchange on site.

Bürkert has developed solenoid valves of Types 7015, 7016 and 7017 for steam, water, hot water, coffee and milk applications for you, which are precisely tailored to the needs of compact fully automatic machines. The solenoid valves of EGV 1935-2004 and FDA are compliant and have an NSF certification.

The new generation solenoid valves for coffee machines

type 7015 – 2/2 way: Media separated plunger valve for coffee, steam, water and hot water
type 7016 – 3/2 way: Media separated plunger valve for coffee, steam, water and hot water
type 7017 – 3/2 way: Media separated rocker valve for dairy products

The advantages of Bürkert solenoid valve solutions:

Opening and closing is easy thanks to tool-free components, which means that the valve range can be serviced quickly and cost-effectively.

The replacement of the core after approx. 100,000 withdrawals can be done quickly and safely by the service department with a twist lock, thus ensuring a short downtime.

The fluid housing of the rocker valve type 7017 can be easily opened using the quick-release fastener. This makes it possible to inspect or replace the diaphragm. The well-known ski boot technology enables the armature to be securely closed after the service.

With the two integrated cylinder bores and the quick-clip holders, the Bürkert solenoid valves can be installed more easily or removed easily and quickly in the event of maintenance.

The more space that the components save, the more compact the fully automatic coffee machine can be. With a volume saving of approx. 8% compared to conventional valves, Bürkert solenoid valves ensure optimal use of space. Thanks to the rocker design, the valve is also easy to clean. On request, the valves can also be offered as a flange variant for direct attachment to the customer’s fluid housing.

For reasons of hygiene, the diaphragm in the valves that are used in milk applications must be replaced regularly. This is greatly simplified by the linking mechanism and has a particularly positive effect on the time account.

Thanks to the food-safe components made of PPS with low thermal conductivity, the temperature drop is counteracted. The steam temperature does not have to be set higher, thus saving valuable energy. The coffee temperature remains constant and the quality of the coffee is not affected.

It goes without saying that solenoid valves have to meet the technical requirements. Extending maintenance intervals and shortening
installation and service times are measurable added values of Bürkert solenoid valves types 7015, 7016 and 7017.
