Jul 2022 | Press information – Smart control valves thanks to IO-Link

Schubert & Salzer Control Systems will present IO-Link positioners for their pneumatic control valves at the ACHEMA 2022.

Ingolstadt, Frankfurt. – Valves that control process and auxiliary media reliably and precisely are an important component in the digitisation of process plants. Schubert & Salzer Control Systems are now offering the latest generation of their tried-and-tested 8049 digital positioner for pneumatic control valves with IO-Link. Important diagnostic data from controller and valve are thus available to plant operating companies. In addition, valve parameters such as dynamics, accuracy and characteristic curve can be simply adapted at any time without physical access. A single cable with an M12 plug bundles the positioning signal, position feedback, data transmission and even the power supply.

Solid advantages for every plant
The integration of the international IO-Link industrial standard in its latest version 1.1.3 facilitates the installation and maintenance of the valves in complex plants. Additional device-specific software or hardware is not required. Incorrect connection is technically impossible due to the coded connecting plug. Even if a replacement should be necessary, this can be done without the need for specialists. The controller adopts the previously used parameterisation automatically by plug & play and is immediately ready for operation after self-calibration.

Predictive maintenance with extensive diagnostic data
The status data provided non-cyclically via IO-Link significantly increase process reliability and plant uptime. Among other things, they enable the predictive planning of maintenance work. "Thanks to the integration of IO-Link, the data from the field level can be monitored continuously. Even the tiniest irregularities are thus noticeable at an early stage", says Peter Hofmann, product engineer at Schubert & Salzer Control Systems. "With the help of the status data, operating companies can react long before there are even any signs of an unplanned plant stoppage. The evaluation makes it easier for the user to estimate preventive maintenance requirements, to avoid a possible impending failure and to continuously optimise the control valve."

Schubert & Salzer Control Systems will present the IO-Link-compatible 8049 positioner to an expert audience for the first time at the ACHEMA 2022. The valve specialists will be available to answer questions about the IO-Link technology and its possible uses at Booth F46 in Hall 11.1 from 22nd to 26th August.

Apr 2022 | Technical Instructions on Air Quality Control amendment 2021 – sliding gate control valves and ball sector valves meet requirements

In May 2021, the German Bundesrat (Federal Council) passed a long-discussed amendment to the Technical Instructions on Air Quality Control (TA Luft), thus specifying among other things stricter maximum values for emissions of harmful substances as well as significantly tightening irrelevance values and minor mass flows.

Following a helium leak test in accordance with ISO 15848-1, a correspondingly high leak-tightness was certified for the sliding gate control valves and ball sector valves from Schubert & Salzer. Therefore, they also meet the higher requirements of the Technical Instructions on Air Quality Control amendment 2021.

Apr 2022 | New: Globe valves type 7017 and type 7027

With the new types 7017 and 7027, Schubert & Salzer's range now includes two globe valves for regulating and shutting off media ranging from neutral to highly aggressive. In a stainless-steel version with nominal sizes from DN 15 to 50, the two valve types are suitable for a wide temperature range from -30 °C to +200 °C (optionally -100 °C to +220 °C) and for nominal pressures up to PN 40. The straight seat design enables a highly efficient and very simple isolation of the valve itself as well as the welded-on pipeline.

Nov 2021 | New sliding gate control valve type 8621, designed in accordance with ASME standards

With the new type 8621, Schubert & Salzer combines ASME standards for the first time with sliding gate technology. It is the first sliding gate control valve not to be built in wafer design, but instead on the basis of ASME B16.34 incl. a flange connection according to ASME B16.5. Sliding gate valves can now be selected with a standardised overall length according to ANSI ISA 75.08.01; plant operators  can quickly and simply replace traditional globe valves by much more efficient valves with sliding gate technology.

In comparison with globe valves, users of sliding gate valves benefit from critical advantages, such as minimal consumption of energy due to small actuation forces and fast response due to small strokes. Other features are the controllability of high differential pressures with small actuators, low-noise and cavitation-insensitive operation as well as high variable Kvs values.

The new sliding gate control valve type 8621 is the first Schubert & Salzer valve to be produced not only in Germany, but also in the USA at our location in Concord, North Carolina.
