Function principle
Additional proportional valves can be provided depending on the application of the HST hydraulic control system within a strip guiding system, e.g. for controlling a pressure roll and/or an immersion roll.
In contrast to the HR hydraulic control unit, the HST hydraulic control system is not equipped with its own oil pump. Instead, the flow rate of oil is generated via the existing central hydraulic system or an additional HA hydraulic power unit.
An HST hydraulic control system is used wherever installation space is at a minimum. Therefore it can even be used in close proximity to the hydraulic cylinder. The HST system is then supplied by the central hydraulic unit or an hydraulic power unit (HA).
The main component of the hydraulic control system is the EMG servo valve. A wide variety of expansion options enable customised solutions (e. g. emergency and block valve „block and bleed“).
Customer benefits
