Feb 2024 | New low flow valve type 7042 for very low flow rates and high-pressure applications

With minimum Kv values of 0.0027 to 1.7 and a nominal pressure of PN320, the new low flow valve type 7042 is ideal for the precise control of very small flow rates as well as in high-pressure applications. It can be used as a safe stop valve, especially for high pressures. The optionally integrated, digital positioner type 8049 is particularly easy to maintain thanks to its top-mounted installation. It is available with IO-Link, IIoT module and in an ATEX or FM version.

The low flow valve type 7042 has a valve body made of stainless steel barstock material, hardened valve spindles and a metallically sealing, replaceable seat seal made of hardened stainless steel or carbide to ensure maximum reliability and a long service life even in high-pressure applications. A special high-pressure packing ensures a high level of tightness, even with hydrogen, for example.

Dec 2023 | New steam test bench for control and on-off valves

Research and development are decisive factors for the quality of the control and on-off valves from Schubert & Salzer Control Systems. With the new steam test bench, the company has now created options for its own product tests that go well beyond the industry standard. Longer and more intensive tests of different valve types and electronic components have been possible at the company's headquarters and production site in Ingolstadt since February 2023.

Outstanding research and development possibilities
All relevant properties of control and on-off valves – such as speed and precision or leak-tightness – can now be tested intensively under real conditions and further improved. Long-term tests and thermal load tests are also performed in-house. The test bench's steam boiler can produce up to 400 kilograms of saturated steam per hour.

As a result, industrial customers benefit from much more application-specific tests and even more practically oriented training courses and presentations, because applications can also be realistically simulated on the new test bench. The investment is thus a very good supplement to the water test bench – which was only modernised a few years ago – in the customer training centre at Schubert & Salzer Control Systems.

Highly efficient energy supply and air conditioning technology for the site
The steam test bench is integrated in a state-of-the-art power station with a combined heat and power plant. The configuration of the plants, which is perfectly tailored to the company's own needs, supplies the entire Schubert & Salzer works site in Ingolstadt with green electricity and thermal energy. The latter is used for heating or, converted by absorption refrigeration, for cooling for the air-conditioning of the premises. A stratified storage tank additionally increases the efficiency and enables the needs-based use of heating and cooling.

The sophisticated plant and building technology enables the valve specialists to further pursue their own climate protection goals and to equip the site for the future in terms of energy. For that reason, the combined heat and power plant is already prepared for the use of green hydrogen.

Nov 2023 | IIoT without plant modification and special knowledge

The digital transformation of industry promises us permanent and global data availability – an ideal that can often only be realised with high expenditure, because the installation of new hardware and wired data infrastructures is time consuming and costly. In addition, the selection, setup and operation of the software for data acquisition and analysis requires specific technical knowledge that must additionally be acquired or purchased.

With its control valves, Schubert & Salzer Control Systems is now solving this problem for customers with a special IIoT module. Even already existing positioners from the valve manufacturer can be retrofitted very easily with the new plug & play solution. The modules are immediately able to make their data available via a mobile phone connection.  Instead of retrieving these data via cable or Bluetooth, the data are now available to the customer all over the world – without having to set foot in the plant.

“In the future, it is intended that our IIoT module will be able to make data available for the user’s own cloud solutions, too. Primarily, we also wanted to develop a plug & play solution with our product. That’s why we offer, as a manner of speaking, a “turnkey” IIoT platform that can also be used by plant operating companies that have no cloud platform of their own. This solution offers global access, a good overview of the data and is immediately ready to use“, explains Christoph Lukasik, Head of Design and Development at Schubert & Salzer.

Benefits for maintenance and service
From commissioning to monitoring to the evaluation of the incoming data for predictive maintenance, IIoT offers the user a wide range of benefits. Beyond that, users also benefit when service is necessary, because in the case of abnormalities and discrepancies in the control behaviour, the plant operating company can enable online access for Schubert & Salzer, via which the relevant data can then be observed. This often makes it possible to make a remote diagnosis and solve the problem within a very short time and without an on-site visit.

Manipulation is physically impossible
A particularly important aspect of the new development was security against cyberattacks and unauthorised access. Communication between the IIoT module and the positioner was therefore deliberately designed as a one-way street. “The module is controlled 100% by the controller. It only sends data to the cloud that the controller actively provides. The module itself cannot request data from the controller or actively execute commands.  It is also not technically capable of making changes to the controller“, Lukasik adds.

IIoT for everyone
Following an exhaustive test and development phase, the first roll-out of the technology has been taking place since April 2023. “The feedback so far has been positive and very promising. Together with our customers and their feedback, we are aiming to optimise the IIoT module even further over the course of the coming year and to adapt it to the needs of the user“, Lukasik concludes.

Nov 2023 | New hygienic angle seat valves for food and beverage production

Schubert & Salzer is extending its range of sterile and aseptic valves by two new types of hygienic angle seat valves. The on-off valve type 7015 and the control valve type 7025 with integrated digital positioner are specially adapted for use in the production of food and beverages. These valves are used, among other things, to control and shut off product streams, drinking water, CO2 and nitrogen, as well as sterile steam and sterile air.

All wetted stainless steel surfaces of the dead-space-optimised valve construction can be manufactured with a surface roughness of less than Ra 0.8 μm. The new valve types in the nominal sizes DN 15-50 and the pressure class PN 40 are suitable for media with temperatures from -30 °C to +170 °C and in special versions even from -50 °C to +180 °C. The batch numbers of all wetted stainless steel parts are traceable. All wetted plastics are FDA-compliant and conform to the EC Regulation 1935/2004 as well as the EU Plastic Regulation 10/2011. Both valve types meet the requirements according to the Technical Instructions on Air Quality Control (12-2021) together with EN ISO 15848-1:2017.

Oct 2023 | New, larger diaphragm actuator for Sliding Gate Valve Type 8021 GS3

With the new 750 cm² diaphragm actuator, sliding gate valves type 8021 can cope with even higher differential pressures. Despite the larger actuator the valves remain light and compact; the installation height and weight change only marginally.
