Hydraulic valves and pumps perform proportional pressure and flow control. Remote pressure transducer is interfaced to the valve for control. If real value of pressure in system remains below relevant reference signal, digital driver regulates in closed-loop spool position, according to flow reference signal. When real pressure becomes close to reference signal, driver automatically performs with closed loop pressure control, with accurate dynamic pressure profiles.
