Attention! For detailed cavity drawing and cavity tools see data port A (1) rise. The valve functions practically independently of the blocks. For machining the cartridge cavity in steel and aluminum
sheet 2.13-1045 pressure in port P (2). Pressure increase in the consumer port A (1) blocks, cavity tools are available (hire or purchase). Please refer to

to above the adjusted value, e.g. through an active consumer, is the data sheets in register 2.13.
