Description of the mountable QPLx5
pressure switches
The QPLx5 pressure switch is designed to monitor the gas pressure. When the
pressure falls below or exceeds the adjusted switching point, the respective electrical
circuit will be opened or changes over.
Caution!
Service note!
The QPLx5 also has to be replaced when replacing a valve.
It is recommended to replace the QPLx5 after over 50,000 cycles or a service
life of 10 years due to the designed lifetime for gas pressure switches
according to AFECOR. It is not recommended to reinstall these, even if the
seals on the valve have been replaced.
