Beschreibung
Zusammenfassung:The electrically controllable pressure regulator contains a balanced pressure regulator valve (5) subjected to pressure from a hydraulic source and to the control pressure in the control pressure line. The control pressure is derived from a series of hydraulic elements producing defined pressure drops connected after a choke (7) exposed to the system pressure. Each element has a by-pass (20) contg. a valve for opening and closing the by-pass. The series circuit of elements is connected to a tank (9) for the hydraulic medium. USE/ADVANTAGE - For industrial machine. Operates simply and reliably and can be connected very simply to digital controller.
