Safety Valve for Pneumatics
The safety valves, preset at the factory and lead sealed, prevent higher
pressurization than permitted of the subsequent pneumatic components.
When the factory settings are exceeded, compressed air audibly escapes.
NOTE: The safety valves for the pneumatic options / for the option Insert gas
equipment are located in the melter tower.
Performance Check
The performance of the safety valve should be checked approx. every six
months. Do this by turning the knurled screw counterclockwise until the
compressed air is audibly released.
After the performance check, turn the knurled screw all the way back again.
If the safety valve does not function properly, it should be cleaned. If it still
does not function, it must be replaced.
NOTE: A defective safety valve may be replaced only with an original spare
part. Only the manufacturer may perform repairs to the safety valve!
