Maintenance intervals
Recommendation for plants subject to strong vibration
●
For plants subject to strong vibration, 6 months after commissioning and then
once a year: Check fastening screws between fail safe unit and valve for tight-
ness. If required, fasten screws while applying the tightening torques as indicated
in chapter <Assembly>.
●
In case supports are mounted, we recommend checking all support screws for
fast tightening. For screws sealed and secured with e.g. thread sealing material,
this action is not required.
Recommendation for areas with explosion hazards:
When deployed in areas where dust formation represents a potential explosion
hazard, perform visual inspection for deposit of dirt or dust on a regular basis. Clean
devices if required.
Recommendation for maintenance:
●
In standard operation (valve opening/closing via the part-turn actuator), no further
actions are required during operation, e.g. grease change. Maintenance intervals
in standard operation depend on the overall combination between actuator
(gearbox), FQM and valve and must be followed according to the operation in-
structions of the mounted components.
●
Generally, the fail safe unit can be operated without maintenance when respect-
ing the specified number of fail safe operations according to the technical data
(opening/closing the valve via spring force). Thereafter, we recommend calling
the AUMA Service for maintenance.
