Imprimir páginaThe pressure limiting valves may only be operated within the values specified in the technical specifications. An
operation outside of the permitted values can overload and damage the seals.
Warning:
With some devices, "overtightening" the adjusting screw (hand wheel, spindle, hexagon) can lead to a much higher
upstream pressure than the maximum factory-specified value.
Operating a pressure limiting valve with a much higher pressure than the factory-specified upstream pressure can
have the following consequences:
• If the setting spring is compressed to a value near the block length, it will show a greatly changed characteristic
curve with a negative effect on the regulating function of the pressure limiting valve (e.g. incomplete opening of the
regulating valve, indicated by a creeping delayed rise or fall of the upstream pressure).
• The internal parts will be subjected to loads beyond their design limits which might deform them permanently.
Damages due to an excessively high setting of the upstream pressure are excluded from any warranty.
4.4 Shutting down
•
Close inlet.
•
Consume remaining medium completely or drain completely.
•
Turn the hand wheel anticlockwise until the pressure range spring is completely relaxed.
5. Maintenance
Do not carry out any maintenance/repair on fixtures that are under
pressure!
Repair and maintenance may only be carried out by trained technicians! Under normal operating conditions, an
inspection is recommended every 6 months during which the device is inspected for external damage and the
function is checked. If operating conditions are unusually excessive, shorter maintenance intervals may be
necessary.
5.1 Troubleshooting
1. Problem: After adjusting the pressure limiting valve, the upstream pressure continues to rise even without any
turns to the adjusting screw (hand wheel, spindle, hexagon).
Possible cause: The valve seat is soiled or the diaphragm or the piston is damaged. Measure: The valve seat,
diaphragm or the piston needs to be cleaned or replaced.
2. Leakages around or at the spring cap or permanent discharging at the output.
Possible cause:
1. The spring cap needs to be retightened.
2. 2. There is dirt or there are scratches on the valve tappet / diaphragm / piston.
Measure: Replace the diaphragm / piston or the tappet (repair kit)
5.3 Spare parts
Only original spare parts may be used for repairs. Replacements are to be carried out only by trained personnel. You
can find spare parts at

5.4 Repairs
Defective devices can be sent in to AirCom Pneumatic GmbH. After a thorough inspection, a cost estimate is
created with results of the inspection.
