Press modules Type IH04 39/56
Proceed as follows when replacing a valve:
▶ Check the hydraulic circuit diagram to see which pressure line is affected and
what the effects of removing the valve are.
▶ Observe the data sheet of the valve to be replaced, which is specified in the
the parts list (e.g. tightening torque, material of the hexagon socket head
cap screws ...).
▶ Make sure that the press module is depressurized by connecting a suitable
measuring device to the provided measuring points.
▶ Please note that some pipeworks of the press module are still under pressure in
the OFF operating mode.
Further information on this topic is included in the product-specific
documentation of the respective press module, see chapter 1.2
"Required and additional documentation".
▶ Check whether the affected valve has cooled down sufficiently for you to
dismantle it.
▶ Dispose of the defective valve, see chapter 13 "Disposal".
▶ Install the new valve.
▶ Check the reaction time of all safety-related valves after the replacement of
a safety-relevant valve.
