4 Description of Function
4.1 Designated Purpose of the Device
CAUTION
The use of other media can cause functional failures, damages or even the destruction of the
device.
Danger from ejected medium under high pressure. Depending on the pressure for
atomization and material, the spraying process can be accompanied by loud noise! We
recommend wearing ear protection.
The AUTOMATIC SMS-11 valve is a pneumatic device and is suitable for the application of greases, oils,
separating agents or colors. 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,
for which the jet width can be individually adjusted. The discharge from the nozzle will be performed through
the selected special air cap as flat or round jet. Depending on the viscosity of the medium to be applied, the
application result can be individually adjusted through the nozzle size, the atomized air pressure or also the
material supply pressure as well as the jet width settings. Supply of spray air, control air and material is
performed through three hoses, respectively four hoses if the jet width settings are performed vie remote
control. The function of the needle is: opening by air pressure / closing by spring pressure. The SMS-11 is
optionally available with raster-needle sensor and material circulation.
The SMS-11 is optionally available with raster-needle sensor, nozzle extensions, clamping holder,
quick-change board, heating plate and material circulation.
