Servicing
9.1 Preparing the valve for
service work
1. Lay out the necessary material and tools
to have them ready for the service work.
2. Put the regulator out of operation (see
the 'Decommissioning' section).
We recommend removing the regulator from
the pipeline before performing any service
work (see the 'Removing the regulator from
the pipeline' section).
The following service work can be per-
formed after preparation is completed:
− Replace the control thermostat (see sec-
tion9.4).
− Replace the seat and plug (see sec-
tion9.5)
Tip
9.2 Installing the regulator
after service work
Î Put the regulator back into operation (see
the 'Start-up' section). Make sure the re-
quirements and conditions for start-up or
putting the valve back into operation are
met.
