Hydraulic Ram Control Unit HSE NG 0 Design and Function Common features of VTHL ram control units: modular design robust valve elements high dynamics simple control structure The integration of all necessary valve components into a manifold mounted directly on the block cylinder results in a compact design and best power density. Together with additional mechanical feedback, the hydraulically piloted main valve forms the basis for the stroke control. Tdc (top dead center) control is always with mechanical closed loop feedback. Bdc (bottom dead center) control may be with electrical feedback or with mechanical feedback control, depending on the application. The hydromechanical design of the stroce control unit offers an accurate and drift-free tdc. Due to the fast steering process, the bdc has a good repatability as well.
