OPERATION
880 Proflame has two automatic shut-off valves. When both of them are de-energised, it is only
possible to measure the inlet pressure on the inlet pressure test point.
When the solenoid EV1 is energised the first gas valve opens. The pilot outlet is enabled.
Energising the second solenoid EV2, the second valve also opens and the gas flows through the
main outlet.
It is possible to measure the outlet pressure on the outlet pressure test point.
The servo pressure regulator diaphragm system allows improved performance of outlet pressure
regulation. The outlet pressure can be adjusted by a screw.
