10. MAINTENANCE, CLEANING
10.1. Safety instructions
DANGER!
Risk of injury from high pressure in the equipment!
• Before loosening the lines and valves, turn off the pressure and
vent the lines.
Risk of injury due to electrical shock!
• Before reaching into the system , switch off the power supply
and secure to prevent reactivation!
• Observe applicable accident prevention and safety regulations
for electrical equipment!
WARNING!
Risk of injury from improper maintenance!
• Installation may be carried out by authorized technicians only
and with the appropriate tools!
Risk of injury from unintentional activation of the system and
an uncontrolled restart!
• Secure system from unintentional activation.
• Following maintenance, ensure a controlled restart.
10.2. Maintenance Work
10.2.1. Actuator
The actuator of the diaphragm valve is maintenance-free provided it is
used according to these operating instructions.
10.2.2. Wearing parts of the Diaphragm Valve
Parts which are subject to natural wear:
• Seals • Diaphragm
→
If leaks occur, replace the particular wearing parts with an appro-
priate spare part. (see Chapter „13. Spare Parts").
A bulging PTFE diaphragm may reduce the flow-rate.
10.2.3. Inspection Intervals
→
Check diaphragm for wear after maximum 10
Muddy and abrasive media require correspondingly shorter

inspection intervals!

10.2.4. Service life of the diaphragm
The service life of the diaphragm depends on the following factors:
• Diaphragm material • Medium temperature
• Medium • Actuator size
• Medium pressure • Control pressure for CFB and CFI
Protecting the diaphragm
→
For CFA match the actuator size (actuator force) to the medium
pressure to be actuated. If required, select the actuator with
reduced spring force EC04.
→
For CFB and CFI try and select the control pressure not higher
than is required to actuate the medium pressure.
