In January 2004, the Germany-based manufacturer Autronic Reglersysteme GmbH delivered three electro hydraulic actuators to valve manufacturer Daume Regelarmaturen GmbH for application in a power plant extension in Munich, Germany. The 4-20mA modulating actuators are equipped with a fail-safe function with spring return and one of them with an accumulator. The actuators are connected to the central hydraulic supply. The valves have been sized up to DN 600 PN40, and their dimensions have a capacity for steam up to 176t/h.
