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).
Tip
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 set point spring (see sec-
tion 9.4)
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.
9.3 Service work
Î Before performing any service work,
preparations must be made to the regu-
lator (see section 9.1).
Î After all service work is completed, check
the regulator before putting it back into
operation (see the 'Testing the regulator'
section).

NOTICE
!
Risk of regulator damage due to exces-
sively high or low tightening torques.
Observe the specified torques when tighten-
ing regulator components. Excessive tighten-
ing torques lead to parts wearing out more
quickly. Parts that are too loose may cause
leakage.
Observe the specified tightening torques.
Note
SAMSON's After-sales Service can support
you concerning lubricant, tightening torques
and tools approved by SAMSON.
The set point ranges adjusted in the factory
can be changed by changing the set point
spring (8) and operating bellows (3).
