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
The
SMS-13
Airless-Spray Valve operates pneumatically. Control air is used to open and close the valve. If
the control air fails or is turned off, it will be closed by the needle spring. The spraying material can be sup-
plied to the valve with a pressure of up to
max. 150 bar
via a high-pressure pump. Please contact the manu-
facturer, if higher pressures are required. The installation of a standard airless nozzle (not included in scope
of delivery) and the accordingly high material pressures result in an airless atomization of the medium.
The needles function s as follows: open through air pressure / close by air pressure.
4.1 Purpose of the Device
CAUTION
The use of other media can cause functional failures, damages or even the destruction
of the device.
The airless spray valves of the
SMS-13
series are spraying devices with airless atomization and are suitable
for the application of liquid media, such as paints or abherents in plastic moulds. External magnetic valves
are employed for the pre-control. Depending on the viscosity of the applied medium, the spraying image can
be individually adjusted through the airless nozzle (not included in scope of delivery) and also through the
material supply pressure. The supply with control air (for opening and closing) and material will be performed
via three hoses. The airless spray valve
SMS-13
is a high precision device with a long, reliable service time if
the following instructions are strictly followed.
