3 Transport
3.1 Packaging
The type of packaging depends on the individual mode of shipping. If not separately contracted, the
packaging is in accordance with the rules and regulations of Walther Systemtechnik GmbH. This rule is in
accordance with the Federal Association for Packaging HPE.
3.2 Tasks before Transport
The following has to be done before transport:
Disconnect all power lines.
The actual transport of the incomplete device and its individual parts requires special care in order to prevent
damages from external forceful impact or careless on- and off-loading. Depending on the mode of
transportation, suitable transport and load securing has to be selected. The incomplete device will be aligned
and leveled by appropriate fastening elements.
4 Description of Function
4.1 Designated Purpose
The spray valves of SMS-05 series are suitable for the application of liquid up to viscous media, such as
grease, oil, separating agents, colors or glues. One of the major characteristics of the SMS-05 series is the
stepless adjusting of the spraying width as well as the integrated control valve for pre air and purging air.
Depending on the viscosity of the medium to be applied, the application pattern can be individually adjusted
via the nozzle size, the atomizing air pressure and material pressure. The supply line of the atomizing air,
control air and the medium takes place via three hoses. Connections No. 7.0 and No. 8.0 are additional op-
tional material connections for the material circulation (i.e. circulation via nozzle head).
CAUTION
The use of other media can cause functional failures, material damages or even the
complete destruction of the device.
The SMS-05 Spraying Valve is an electro-pneumatically controlled application device. Extremely short
control air paths, facilitated by the directly attached 3/2-way solenoid valve (pos.18.0), bring about a fast and
very exact opening and closing of the needle (pos.13.0). The air valve (pos.12.0) connected with the needle
(pos.13.0) receives air pressure on the surface via the 3/2-way solenoid valve. This opens the air valve
(pos.12.0) such that the atomizing air (“pre air”) is released. Not until the spring (pos.12.4) is completely
compressed, the air valve (pos. 12.0) moves the needle (pos.13.0), and the medium comes out of the
nozzle. If the control air is switched off or fails, this spring (pos. 14.0) will cause the needle to close, whereby
the needle first closes the nozzle and thereafter the air valve (“purging air”) will close. The pre air and the
purging air help to keep the nozzle (pos. 3.0) clean.
The material pressure (1/8"-connection - pos. 5.0) must be adjusted to the desired spray pattern and, thus, to
the atomizing air pressure (1/8"-connection - pos. 17.0).
It can be used for continuous as well as intermittent spraying. The control air impulses (M5-connection - pos.
16.0) are transmitted to the working piston via the 3/2-way solenoid valve (pos. 18.0).
Depending on the particular application case it must be ensured that the control air is adjusted to the number
of operating cycles.

4.3 Type Label
The type designation is etched in the casing. The serial number is
also inscribed in this area.
5 Mounting and First Start-up
The valves can be installed in any position. The spraying width for middle air (ML) and cone air (HL) can be
individually regulated. The possibility for using either round or flat spray air caps is given.
Vibrations of the valve caused by fast intermitting cycles require solid and tight installation. Excessive
machine vibrations to the valves should be avoided.
5.1 Hose Mounting
The three functional hoses will be connected as follows:
Atomizing air (blue)
Connection ZL (17.0): M5
Control air (black)
Connection SL (16.0): 1/8"

5.3 Adjusting the Device
The amount of material can be regulated via the stroke adjustment of the needle. A left turn of the regulating
knob increases the material amount. A fine precision thread affects a needle rise that results in an adjust-
ment of 0.5 mm with each turn of the adjusting knob.
IMPORTANT
Do not turn the regulating knob further to the left if no more stops are noticeable while turning
it! The maximum fluid outlet has been reached!
A further turning will damage the raster needle screw!
IMPORTANT
Nozzle and needle can be damaged by wrong handling. Only decrease the material flow (by a
right turn of the regulating knob) if material spills out. Do not turn the regulating knob further to
the right after the nozzle is closed!
NOTE
The duration of the post-spray air will be individually adjusted from outside at the spray valve.
Turn the regulating screw (10.4.0) which is inserted in the side (view in spray direction: right)
with a screwdriver in order to control the duration of the post-spray air as follows:
right turn = longer duration of post-spray air
left turn = shorter duration of post-spray air
Basic setting = screw is flush with basic body; then make one full turn to the
right

5.4 SMS-05 with Raster Needle Sensor
Optionally, you can use a raster-needle lock with a pre-installed, inductive proximity switch. It will release a
signal when the needle piston with the needle is open. This will help you in digitally monitoring the status
„nozzle open“.
