It integrates multiple traditionally standalone units into a compact, all-in-one system, and this integrated solution addresses the jamming, clogging and leakage failures of servo valves in power plants, which are induced by substandard EH oil parameters—including acid number, sludge and varnish deposits, moisture content, volume resistivity and particulate contamination levels. In doing so, it ensures the long-term safe and stable operation of the entire power generation system.
