Dismantling – Assembly
Fitting of the SVP aseptic change-over valves may only be carried out by
specially trained, qualified personnel.
Training or instruction in accordance with the current safety standards.
For systems with explosion protection:
training or instruction or authorization to carry out work on systems subject
to explosion hazards (observe ATEX regulations).
Obtain information on possible risks that could be caused by residues of the
operating media and take appropriate measures if necessary (safety gloves,
safety goggles, etc.), before carrying out maintenance and service work on
the SVP aseptic change-over valve.
Before disconnecting the valve connections and the flange connection of the
valve housings, make sure that
this work is only carried out in a depressurized state and with the media
supply shut off.
the SVP aseptic change-over valve and all piping elements leading to the
valve have been drained and cleaned or flushed.
the fittings have cooled down.
the system cannot be started by a third person.
the pressure build-up which may form in sealed pipelines is counteracted.
disassembly - assembly of the SVP aseptic change-over valve are carried
out according to the assembly instructions.
when dismantling the control unit, the closing spring is preloaded with auxil-
iary assembly air. To actuate the valves in the manual mode, the supply
voltage and/or electrical signal must be applied.
when dismounting the control unit, the closing spring is to be preloaded. In
case of non-compliance there is a risk of injury when removing the clamp
connection, due to the released spring tension of the actuator.
Secure SVP aseptic change-over valves against signaling, voltage and sig-
nal cut-off, operation and actuation.
the power supply has been disconnected.
the SVP aseptic change-over valve is removed from the piping section, if
possible.
Cordon off assembly area.
Ensure that the assembly area remains cordoned off while work is being per-
formed.
