This series of hydraulicdished head machine is used for bending and cold forming for hermetic cover of large scale pressure vessel.Hydraulic cartridge valves adopt integrated control systems,reliability service,long life,small hydraulic shock.It has individual electrical systems,adopts PLC button centralized control.It can be operated both fixed press and fixed tenor by means of moving the operation panel for selection.Work pressure,pressing speed,tenor can be required under the process within the parameters required adjustment. Main features: 1.good appearance and steady performance 2. It has individual power construction and electrical system,adops PLC botton centralzed control,which can be conveniently adjuste and opereated both manually and automatically. 3.main circuit:50HZ/380-415V,three phase , control circuit is DC24V.
