DESCRIPTION AND THEORY OF OPERATION
THEORY OF OPERATION
Air Manifold Assembly
The Air Manifold Assembly is located in the Instrument/Solenoid Panel Box. The manifold is comprised of
six solenoid valves that are activated by the PLC to operate automatic valves in the TWPS. The solenoid
valves and the automatic valves that they control are as follows (see Figure 22):
- Solenoid Valve XV-904 controls 100 psig air to MF Main Feed Valve V-111
- Solenoid Valve XV-905 controls 100 psig air to MF Upper Feed Inlet Valve V-112
- Solenoid Valve VX-906 controls 100 psig air to MF Lower Feed Inlet Valve V-113
- Solenoid Valve XV-907 controls 100 psig air to MF Upper Shell Outlet Valve V-401
- Solenoid Valve XV-908 controls 100 psig air to MF Lower Shell Outlet Valve V-402
- Solenoid Valve XV-909 controls 100 psig air to MF Upper Filtrate Outlet Valve V-201
