The first "smart" dome pressure regulator

757 LE/S Smart - dome pressure regulator with integrated digital sensor technology


With the 757 LE/S Smart, Witt-Gasetechnik has launched the world's first dome pressure regulator with integrated digital sensor technology. The "4.0" fitting can be regarded as a milestone in the digital networking of gas technology systems.

Witt dome pressure regulators are of immense importance for the performance of many industrial processes: They ensure a constant gas pressure independent of fluctuating flow rates, temperatures and inlet pressures. However, they were not digitally networked until now - like almost all valves in use in gas technology.

Pressure, temperature and flow rate in real time

The smart Witt dome pressure regulator measures the inlet and outlet pressures as well as the gas temperature at the inlet and outlet. Until now, these values could only be measured using additional, external sensors and transmitters, which had to be installed separately in the pipeline. This ground-breaking integration enables a much more compact, reliable and economical solution. A further unique selling point: The built-in software uses the recorded data including the Cv value to calculate the gas flow rate, and thus provides the user with additional valuable information on the process performance.

"The Model 757 LE/S is the first pressure regulator with fully integrated measuring electronics," underlines Andrew Smart, Sales Manager at the manufacturer Witt. "This patented in-house development features all the sensors necessary for the monitoring of the gas supply: For maximum precision, control, consistency and safety in the process".

The measured and calculated data are displayed in real time on a small display in the valve and sent to the required location via a network connection. For example, the data can be transmitted via telemetry systems from cryogenic gas tanks. This enables those responsible to intervene quickly when action is required. This ensures maximum operational reliability, process control and a high level of transparency.

Despite built-in sensors, the dome pressure regulator is extremely compact. It can also be easily installed in the pipeline at a later date.

Witt dome pressure regulators offer unmatched performance

Witt dome pressure regulators give uniquely accurate pressure control, with the pressure curve remaining practically unchanged over the entire flow rate range. They adapt very swiftly to changes in the upstream pressure, avoiding pressure fluctuations and the notorious “flutter” effect.

The 757 LE/S is a completely new generation of valves for "Industry 4.0". Industry 4.0 is a term originally coined by the German government, referring to the digitalisation of production processes.

Witt started in 1945 and is today considered one of the world's leading manufacturers of valves and apparatus for gas plants. The company is working intensively on digitally integrable solutions that offer genuine added value: just one component, faster installation, less space requirement, networked control and monitoring, and cost advantages over piecemeal solutions.
