In the case of a filter pressure regulator with manual or semi-automatic drain valve, the condensate must be drained
regularly; this is not necessary for a filter pressure regulator with automatic drain valve.
The desired output pressure is set by turning the adjusting screw (hand wheel, spindle, hexagon). Turning clockwise
increases the output pressure, turning counterclockwise decreases the output pressure. If the filter pressure
regulator is not self-relieving (without secondary venting), the medium must be able to drain from the outlet of the
filter pressure regulator; otherwise the outlet pressure will not be reduced.
The general function of a filter pressure regulator is described in the following short movie.
Animation film Compressed air filter
Fine adjustments should always be made in the direction of pressure increase in order to reach the exact setting
point. The filter pressure regulators function with all media that are compatible with the specified materials. The filter
pressure regulators 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
back pressure than the maximum factory-specified value. Operating a filter pressure regulator with a much higher
back pressure than the factory-specified 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 filter pressure regulator (e.g. incomplete closing of the
regulator main valve, indicated by a creeping delayed rise or fall of the back 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 back pressure are excluded from any warranty.
4.4 Shutting down
•
Close inlet.
•
Consume remaining medium completely or drain completely.
•
Turn the hand wheel counterclockwise until the pressure range spring is completely relaxed.
•
Once the pressure has been reduced completely, the housing can be opened for maintenance.
5. Maintenance
Do not carry out any maintenance / repair on fixtures that are under
pressure!
Repair and maintenance and 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 regulator, the back pressure continues to rise even without turning the adjusting
screw (hand wheel, spindle, hexagon). Possible cause: The valve seat is dirty or damaged. Measure: Clean or
replace the valve seat.
2. Problem: Leak around or at the spring cap.
Possible cause:
1. Retighten the spring cap.
2. There is dirt or there are scratches on the valve tappet / diaphragm / piston. Measure: Replace the diaphragm /
piston or the tappet (repair kit)
