Danger!
Depressurize
and, if possible, discharge the line and cleaning
system before any maintenance work.
Do not touch the yoke area or actuating area (positioner) when the
valve is installed. Risk of injury through sudden valve operation.
Electric and pneumatic lines must be disconnected before assembly
or disassembly of the valve (e.g. for seal replacement).
Do not reach into the valve body when the valve is dismantled.
Observe instructions given for valve in installed state.
Regular maintenance including replacement of all seals,
diaphragms and guide bushings must be scheduled in order to
prevent leakages.
In case of damage of the diaphragm, fluids will leak from the
leakage bore in the yoke area. Leakages must be drained safely.
Risk of burn
To prevent personal injury, the valves must not be touched
during CIP cleaning or sterilization with hot water or steam.
Observe Service Instructions to ensure safe maintenance of the
valve. The valve must only be assembled, disassembled and
reassembled by persons who have been trained in APV valves or
by SPX FLOW service team members. If necessary, contact your
local SPX FLOW representative.
