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-07 valve is a pneumatic device. It will be opened by control air and will be closed by a needle
spring in case of failure or turn-off of the control air. The spray medium will be supplied into the valve from a
pressured container or via a pump. The separately controlled spray air distributes the material into the actual
spray jet. The discharge from the nozzle will be performed through the selected special air cap as flat or
round jet. The function of the needle is: opening by air pressure / closing by spring 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 SMS-07 spray valve is suitable for the finest application of low-viscous media such as colors or release
agents in plastic moulds, or high-viscous media such as grease. Depending on the selected air cap, a flat or
a round jet can be generated. Depending on the viscosity of the medium to be applied, the application result
can be individually adjusted through the nozzle size, the spray air pressure or also the material supply
pressure. Supply of spray air, control air and material is performed through three hoses. The SMS-07 spray
valve is a high-precision device which will be a long-term reliable tool if the following notes are observed.
