Description and function of the valve and container unit
The unit consists of one special steel compressed container with liquid filter
(100…120my), valve group and service module for storing liquids used in MMKS
devices of HPM.
Do not pour dirty fluid in the container.
Close container tightly after filling.
The unfiltered and unoiled compressed air (6 – 9 bar) is connected with the service
module. Spray air pressure is adjusted by the pressure regulator.
We recommend a low spray air pressure of 0.5 up to
max. 2.5 bar.
Magnetic valves in the air and liquid feed tubes allow assembly of valve and
container units up to max. 1,000 mm above or below the spray heads. Larger
differences are possible by adjusting the liquid pressure. I.e. if several spray heads
are used, it is possible to position them at different levels from each other as well as
from the valve and container unit.
Control valves may only be operated at the levels indicated for tension, control
current or control air pressure. See specification label.
The valves must not be used in hazardous or wet areas.
If the current is interrupted, the valves are closed. If the current is switched on, the
valves are opened simultaneously and both spray air and fluid can flow to the spray
head.
Spray start, duration and spray stop are controlled by valves activated from the
customer's control unit.
Without or with level control (with existing level control, please refer to enclosed
measurement sheet).
The level control must not be used in hazardous or wet areas.

• Assembly at the place of installation and connection to the pressure tube
must be executed by skilled staff. Control technique and evaluation must be
performed by client’s skilled staff.
• Connection tubes and couplings must be appropriate for the permitted
pressure and temperature range.
• Start spraying device, adjust spray nozzles (see the corresponding Operating
Instructions of your spray head).
Operation
Avoid strong shaking or vibrations.
Certain applications require operation and hazard
instructions. If necessary, such information must be
completed by the operator. The service staff must be
instructed.
Maintenance / Inspection
(depends on the applied liquid)
Every four weeks at the latest:
• Check and if necessary, clean the container (this must be done
weekly or on a daily basis when using fluids that create waxy
residues).
• Check and clean the fluid circuits, if necessary (this must be
done weekly or on a daily basis when using fluids that create
waxy residues).

If it doesn’t work properly
Tips and tricks you can use.
Liquid is not siphoned, nozzles do not spray full, round cones, nozzle “spits”:
There is a sealing element missing from the nozzle (please check according to spare
part list).
Check tubes and tube joints for leakage (there should be no air bubbles in the liquid
tubes).
Check valve is blocked or damaged:
Clean or replace it, do not remove it.
Solid impurities have been collected between the inner (air) and outer (liquid)
nozzle (cuttings, small grains, film impurities, dirt from air pressure feed line):
Carefully brush inside and outside surface of nozzle with cleaning agent or replace
nozzle. Rinse with solvent before stoppages.
In the event of frequent occurrence, fit with a flushing device (available as an
option).
Outer / inner nozzle were damaged mechanically:
Nozzle must be replaced.
Nozzle was bored subsequently:
In this case install original nozzle.
Check small filter in container:
If dirty, clean or replace.

When spray air pressure is reduced, the spray jet of one nozzle subsides
considerably earlier than that of the others (if using several spray heads):
Solid impurities were collected between the inner (air) and outer (liquid) nozzle –
carefully brush inner and outer nozzle surfaces with suitable solvent (use soft brush).
Ask your liquid supplier for a suitable solvent or cleaning agent!
Air bubbles in liquid tubes, liquid runs back into container:
Individual parts (such as O-ring, screw plugs, trust washer etc.) are damaged or
completely missing (please check items according to spare part list).
Inner nozzle was mechanically damaged - Nozzle must be replaced.
Liquid deposits appear on the conical surfaces of the inner nozzle and outer
nozzle (inside):
Clean with solvent and soft brush, immerse outer nozzle in solvent if necessary, then
blow through thoroughly.
In such cases, always clean regularly or flush through with solvent before stoppages.
Bore of outer nozzle is damaged or dirty (cuttings, deposits, etc.):
Clean or replace nozzle.
The spray cone is too narrow (jet formation), nozzle drops:
Liquid pressure is too high – adjust at the pressure regulator.
Outer nozzle is opened too far: Reduce opening.

Dripping during spraying (particularly with thicker spraying media):
Change nozzle setting – reduce liquid flow and raise spray air pressure slightly.
Check whether nozzle is damaged or whether the nozzle output is reduced by
deposits / film formation – replace or clean nozzle.
Dripping at the end of a spraying phase (particularly with thinner spraying
media):
Reduce liquid pressure at the pressure regulator.
Fit a spring-loaded check valve at the liquid inlet of the spray head. Or if already
fitted, the valve is possibly defective.
Nozzle opened too much (max. two rotations).
Device does not stop or the liquid in the container runs out completely:
Put hand lever of the valves in horizontal position, activation is effected by the
client’s control unit.
Use vertical position of the hand lever only for maintenance work or for quantity
adjustment of the nozzle.
