4.10. DISCHARGE
At the end of the PROCESS cycle, the DRAINAGE phase starts to allow draining all the steam present in the
chamber, with a vacuum decrease to the value of - 0.80 bar.
As for previous VACUUM DECREASE phases, also the DRAINAGE includes a first spontaneous depressurization
that exploits the pressure generated by the steam and that only requires the control of drainage solenoid valves EV1
and EV3.
To complete the DRAINAGE until reaching the value of 0.50 bar, the decrease continues by means of the vacuum
pump and the simultaneous activation of solenoid valve EV4.
In this phase too, activations of solenoid valve EV2 are required to balance the pressure value inside the hydraulic
circuit and facilitate the activation of the vacuum pump.
