(contd.)
The pneumatic pressure control valves (1) can be installed instead of the
mechanical pressure control valves. They are also located in the manifold.
They are connected to the pneumatic control unit in the melter with one
pneumatic hose each.
There are air relief valves (1) in the manifold. Their purpose is to allow the
air entering the manifold when the filter cartridge is replaced to escape.
