7 Servicing
The regulator does not require any mainte-
nance. Nevertheless, it is subject to natural
wear, particularly at the seat, plug and oper-
ating diaphragm/bellows. Depending on the
operating conditions, check the regulator at
regular intervals to avoid possible malfunc-
tions.
We recommend removing the regulator from
the pipeline before performing any mainte-
nance or service work.
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 concerned
as well as the regulator.
− Disconnect the control line.
− Drain the process medium from all the
plant sections concerned as well as the
regulator.
− Wear personal protective equipment.
Risk of personal injury due to residual pro-
cess medium in the regulator.
While working on the regulator, residual
process medium can escape and, depending
on its properties, may lead to personal in-
jury, e.g. (chemical) burns.
Wear protective clothing, safety gloves and
eyewear.
