7 Maintenance
The control valve is subject to normal wear,
especially at the seat, plug and packing. De-
pending on the operating conditions, check
the valve at regular intervals to prevent pos -
sible failure before it can occur.
SAMSON’s After-sales Service department
can support you to draw up a maintenance
plan for your plant.
We recommend removing the valve from the
pipeline for service or repair work (see sec-
tion 9.2).
Risk of bursting in pressure equipment.
Control valves and pipelines are pressure
equipment. Improper opening can lead to
valve components bursting.
−
Before starting any work on the control
valve, depressurize all plant sections con-
cerned and the valve.
− Drain the process medium from all the
plant sections concerned as well as the
valve.
−
Wear personal protective equipment.
Risk of personal injury due to sudden escape
of process medium.
The valve has a safety bleed to detect dam-
aged or worn O-rings. The process medium
may escape suddenly and at high pressure.
− Wear protective clothing, gloves and eye-
wear when working near or on the valve.
− Do not stay in the range of the safety bleed
longer than necessary.
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.
(chemical) burns.
Wear protective clothing, gloves and eye-
wear.
Risk of burn injuries due to hot or cold com-
ponents and pipeline.
Valve components and the pipeline may be-
come very hot or cold. Risk of burn injuries.
−
Allow components and pipelines to cool
down or heat up.
−
Wear protective clothing and gloves.
