The TRB 700 and general safety regulations must be observed unconditionally
during repair.
Qualified personnel must always be present when repair and maintenance are
carried out (see paragraph "Qualified Personnel").
Valve housing, bonnet, pipe piece
Pressurised parts
Effects
Piping stressed beyond permitted
limits, recoil forces, pressure
surges, valve used as fixed point,
permitted pressure and
temperature limits not observed
Improper transport, bending
stresses too great, thermal stress
Valve without actuator
Flow control
Flange fittings loosen under
pressure, bolts not tightened
diagonally
Valve without insulation, carrying
hot fluid, too easily reached
Cause
Reduce pressure and
stress, change piping
position, install
compensators, select other
materials, replace valve
replace valve, ensure that
piping is laid free of stress
or tension
Proper installation in
accordance with these
operating instructions
Insulate valve or install
protective device
