Solenoid valves for easy installation and quick maintenance

Bürkert's new solenoid valve series, developed in close collaboration with leading manufacturers of fully automatic coffee machines, prioritises the life cycle and service levels of both the machines and the valves. Drawing on extensive experience in installation, operation, and service, Bürkert integrated feedback from machine manufacturers into the development process. The result is a valve series distinguished by its innovative service approach, with a focus on optimal installation and safe maintenance during operation.

Challenges for solenoid valves in fully automatic systems

Maintaining and servicing fully automatic systems

In various industries, fully automatic systems operate continuously, requiring reliable maintenance and service to ensure uninterrupted operation. Ensuring safe, easy, and tool-free maintenance is crucial to maintain operational efficiency and revenue.

Demand for compactness in fully automatic systems

There's a growing trend towards smaller, more compact, fully automatic systems, such as automatic coffee machines. To accommodate this trend, solenoid valves used in these systems must be smaller yet more powerful.

Requirements for media compatibility and material resistance

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 new generation solenoid valves for coffee machines

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.

The calculation example illustrates the added value of the new Bürkert solutions.

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 valve Types: 7015, 7016 and 7017.
