8 Malfunctions
The malfunctions listed in Table 5 are caused
by mechanical faults and incorrect regulator
sizing. In the simplest case, the functioning
can be restored following the recommended
action. Special tools may be required for re-
pair work.
Depending on the operating conditions,
check the valve at certain intervals to prevent
a possible failure before it can occur. Plant
operators are responsible for drawing up an
inspection and test plan.
