8 Servicing

The regulator does not require any mainte-
nance. Nevertheless, it is subject to natural
wear, particularly at the seat, plug and con-
trol thermostat. Depending on the operating
conditions, check the regulator at regular in-
tervals to avoid possible malfunctions.
Before performing any work on the tempera-
ture regulator, we recommend removing the
valve from the pipeline.
DANGER
!
Risk of bursting in pressure equipment.
Regulators and pipelines are pressure equip-
ment. Improper opening can lead to bursting
of the regulator.
− Before starting any work on the regulator,
depressurize all plant sections affected as
well as the valve.
− Drain the process medium from all the
plant sections affected as well as the valve.
− Wear personal protective equipment.
WARNING
!
Risk of personal injury due to residual pro-
cess medium in the valve.
While working on the valve, residual process
medium can escape and, depending on its
properties, may lead to personal injury, e.g.
burns.
Wear protective clothing, safety gloves and
eye protection.
