2.2 Swivel housing:
The swivel housing supplies the material from the connection housing to the central body and the cylinder
unit. The swivel housing consists of three main parts which are the material chamber (1), the air chamber
(2), and the solenoid valves (3). The external solenoid valves supply compressed air to the cylinder unit.
There is one inlet channel (5) and one return channel (6) in the material housing. In case no circulation is
used both are used as inlet channels. Note also the drainage holes (7) that connects to the front and back
drainage chambers.
The internals of the material chamber differs depending on if circulation (8) is used or if no circulation (9) is
required. The extra seal ring (10) allows for full circulation up to the nozzle head of the applicator.
