Description

Required tool

Electrical power and compressed air is required to perform steps 1 to 11 during
disassembly respectively 11 to 1 during assembly.

1. Set the valve to local mode

2. Activate “Maintenance” (reduced speed)

Now us the position buttons to move the
valve plate. The valve will now move in a
very low speed

Alternatively, the remote interface can be
used:

Set “Control Mode” to ‘Maintenance’

Now use “Target Position” to move the
valve

Service cable

(PC to valve

Service

connector)

3. Vent both valve chambers.

4. Open the 4 bonnet screws and remove

valve bonnet.

Allen wrench

5mm
