INTERNAL INSPECTION
If the valve does not work properly, do not dismount the resetting mechanism, but replace it with
a new one.
THREADED MODELS
-
Shut ball valve upstream the system and make sure no pressure is inside the valve.
-
Reset the valve (valve open).
-
Unscrew the knob, but do not remove the nut below. This is to avoid the accidental
dismounting of the resetting mechanism.
-
Remove the locking nut and the coil.
-
Using an Allen key, remove the screws on the upper flange, in cross way. The gas in the
valve will come out during this step.
-
Check the main O-ring. If necessary, replace it.
-
Blow the spring with compressed air and check it is corrosion free.
-
Check the conditions of the sealing gasket. If gasket is deteriorated, replace it with a new
one.
-
Clean the sealing lip with a clean cloth. Do not use tools, because a lip damage could
result.
-
Remove the filter and blow it with compressed air.
-
Reassemble the valve following the inverse sequence.
FLANGED MODELS
-
Shut ball valve upstream the system and make sure no pressure is inside the valve.
-
Unscrew the knob.
-
Using an Allen key, remove the screws on the upper flange, in cross way. The gas in the
valve will come out during this step.
-
Check the main O-ring and the rod O-ring. If necessary, replace them.
-
Remove the spring and blow it with compressed air. Check the spring is corrosion free.
-
Clean the disc assembly with a clean cloth and compressed air. Grease the rod O-ring.
-
Check the conditions of the sealing gasket. If gasket is deteriorated, replace it with a new
one.
-
Clean the sealing lip with a clean cloth. Do not use tools, because a lip damage could
result.
-
Remove the filter and blow it with compressed air.
-
Reassemble the valve following the inverse sequence.
To insert the rod inside the flange assembly, power the coil and, using a screw driver, move the
pin to allow the rod inserting.
When the reassembly is completed, check the proper sealing between the upper flange and the
valve body:
-
Open ball valve to restore pressure into the valve.
-
Apply a soap solution between the upper flange and the valve body and check for
leakages.
-
Remove the soap solution with a clean cloth and compressed air.
WARNING
To prevent product damage and dangerous situations, read the Installation and Service
Instructions carefully.
Turn off all power before servicing any part of the system.
Make sure that the resetting rod is always free to move and no impediment hinders the
valve closing.
Perform leak and functional tests after mounting (max. testing pressure 1,5 Pmax).
Use all gaskets properly (void warranty).
All wiring must be in compliance with local and national codes.
Make sure all works are performed by qualified technicians only.
