DESCRIPTION OF FUNCTIONS

Compressed air is fed from a pressure tank
pressure regulation valve
The air supply from the pressure tank to the 2K device can be interrupted by the ball valve
4
The ball valve is used to release condense manually, - an automatic moisture trap is
recommended here.
6
The safety valve protects the pressure tank against unacceptable air pressure increases (e.g.
when heated).
Because it is required and the compressed air supply
alone, the piston pump also features a safety valve
During operation of the piston pump air motor, the compressed air escapes into the atmosphere via
8
the silencer , thus relieving its pressure.
The fluids (A = base and B = hardener ) are sucked out of the containers (A =

The strainers protect the 2K device against foreign substances that might have accidentally
entered the fluid.
A wet cup (flushing agent tank)
as well as for valve units of this design and is decisive for its installation.
If the equipment is not operated for a longer period of time (exceeding the processing time), it must be
flushed from the valve unit

During the flushing procedure the pressurized solvent is led to the valve unit
along the suction line
The ND models have a pressure regulation valve with a manifold for a bursting disc

THE 2K DEVICE
The functional description of the 2K device can be found in the corresponding section in the

THE COMPRESSED AIR SUPPLY
The compressed air supply consists of the compressor, the pressure tank with moisture trap, possibly
a compressed air drier and pipeline. The compressed air supply is generally already available to the
user.
