VOITH I/H Converter DSG

Voith I/H Converter DSG unit

Description:

The Voith I/H Converter DSG is a current‑to‑pressure converter (CPC) designed for precise electro‑hydraulic control in turbine, compressor, and other industrial fluid‑power systems. By converting a constant input hydraulic supply into a variable, demand‑controlled output pressure (via a 0/4–20 mA control signal), the DSG ensures accurate, dynamic actuation of pilot valves — enabling exact regulation of mass flow and system response. Compact and robust, the DSG converter is engineered for high reliability, minimal maintenance, and long-term operational availability even in demanding industrial environments.

  • High reliability & uptime — The DSG converter has an exceptionally high Mean Time Between Failures (MTBF), reportedly over 600 years (calculated per MIL‑HDBK‑217 / Siemens SN 29500), significantly reducing unexpected downtime.

  • Precise & dynamic control — With input signal control (0/4–20 mA) and fine output pressure adjustment, the DSG offers very accurate control with minimal hysteresis and high resolution, enabling stable and repeatable actuation.

  • Insensitive to pilot oil contamination — The converter tolerates turbine lubricating oil as operating fluid; contamination in pilot-fluid supply has limited effect, simplifying maintenance and reducing oil‑system complexity.

  • Compact and easy to integrate — Standardized interfaces and mechanical design facilitate retrofit or replacement of legacy CPC/CPC‑II devices from other manufacturers.

  • Flexible and safe — Output pressure can be adjusted on‑site via potentiometers; explosion‑proof variants (ATEX, CSA, IECEx, etc.) are available for hazardous‑area applications.
