Protect the electric connection from humidity. If the valve is mounted outside arrange for
adequate cover. Protection class IP65 is only for short periods of humidity. Choose the adequate
connection cable according to the surrounding area and the local conditions, e.g. high
temperature. If you have ignitable atmosphere you have to follow the regulations of your local
accreditation agency.
Maintenance and fault clearance
Our solenoid valves are maintenance-free!
Possible failures
First of all check the connection tags on the body with your medium flow, the voltage, the place of
installation and the working pressure!
Also check if the valve seat, the sealing, the plunger and the tube are clean.
The plunger is not lifted.
1. The connection voltage is broken or not high enough.
2. The solenoid or the rectifier is broken.
3. The plunger is blocked due to polluted plunger area. If the plunger can not reach the final
position this can lead to a broken solenoid (only with energized AC - solenoid) Thermal overload!
4. Nominal voltage and solenoid voltage are different.
The valve does not close properly!
1. The plunger is blocked.
2. There is still nominal voltage.
3. Manual override is not reset.
4. Connection tags on the body and medium flow are not in the same direction.
The valve does not open properly!
1. Diaphragm or piston is broken.
2. The relief boring is blocked (please check the sealing compound or the screwing in the outlet)
3. Anchor space is soiled
4. Nominal voltage is not present.
5. The solenoid is broken.
6. Nominal voltage and solenoid voltage are different.
Repair is allowed for skilled employees only!
