The Voith VOITH electro-hydraulic converter DSG-B07112 is a high-performance hydraulic controller designed to provide superior steam and oil valve actuator control for steam turbine control systems. The VOITH electro-hydraulic converter can convert the 4-20MA signal of the electronic governor into a hydraulic signal and supply it to the power cylinder, so as to control the main steam valve of the steam turbine, and control the on/off and speed of the steam turbine.

The Voith VOITH electro-hydraulic converter DSG-B07112 has a number of features, the most important of which is its magnetic actuation and the pressure reducing valve in the hydraulic section, which together make it function as a pressure regulating valve. In addition, dynamic and hysteresis-free conversion results are better than 0.1% accuracy and are not affected by air gaps, hysteresis, temperature or voltage fluctuations.
It is recommended to filter the oil to NAS1638 level 7 or IS04408 class 16/13. The change from the mA input signal to the proportional stable pressure time is short (t<35 ms). In harsh environments, the electronic and mechanical parts ensure full functionality. All the electronic components of Voith electro-hydraulic converters are contained in the container. Designed to ensure higher input pressures (0~3000psi pressure range can be supplied). Available in standard and explosion-proof versions.
