7.1.5. Wear part exchange
The device includes a solenoid valve and a piston valve whose seals are dynamically stressed; they are subject to wear and
must therefore be exchanged cyclical.
The service life of these parts is many million switchings, however, it depends strongly on the actual runtime of the plant
and possibly also on the air contaminants.
The following values are listed as guide values for the preventive maintenance:
•
Single shift operation (260 work days/year)
•
Continuous operation 24/7
The normal wear at these parts - surface abrasion or deformations at the seat areas - has no impact on the function.
The full purge air volume flows continuously and the control function has no impact if the wear of the seals is too large or if
the seals are destroyed, e.g. due to the impact of aggressive compressed air ingredients or significant ageing.
This system condition will not be detected by the device as a failure (red LED not illuminated) because the requirements for
the set degree of drying are fulfilled.
A required exchange of the wear parts during the warranty period does therefore not establish a warranty claim, but it
represents normal maintenance effort.
Please contact the service of BEKO TECHNOLOGIES GmbH if maintenance cycles are required significantly more often for
specific applications/installations.
