2.4 Correct Use

This device is a needle valve and will be used for processing materials which can be sprayed in continuous
or intermitting operation. Under no circumstances shall aggressive media such as acids, alkaline solutions,
detergents, chemicals or others be sprayed. If you are not sure, please contact the manufacturer if a certain
spray medium is suitable for this device.

2.5 Incorrect Use

 Operating the device with insufficient knowledge about the operation, maintenance and care of the de-

vice.

 Making changes, extensions or alterations on the device that may hamper its safety without the prior

consent of Walther Systemtechnik GmbH.

 Operating the device with defective safety installations or not properly attached or malfunctioning safety

devices.

 Using unsuitable materials.
 Handling the device while energized

2.6 Qualification of Personnel

Only trained and instructed personnel may conduct work on the equipment.
The responsibilities of the personnel for assembly work, operation, repair work or maintenance work must be
clearly assigned to individuals!

Persons in training may work with the equipment only under supervision of an experienced person.

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 automatic spray valves of the SMS-22 series are pneumatically controlled and are suitable for the finest
application of liquid up to pasty media, such as adherents, oils or greases or colors. The spraying process is
produced through the control air, the material supply pressure and the atomizer air; and it can be either in­termittent or continuous. Depending on the selected air cap, a flat jet or a round jet will be produced. The
needle function is: open through air pressure / close through air pressure.

4.1 Purpose of the Device

Control air will be supplied to the spraying device via a 5/2-way pilot valve (not included in delivery); when in
basic position it has a passage for closing the needle. If the pilot valve receives a signal, the front area of the
needle piston will be filled with air which causes the needle piston to push back the spring, and the needle
opens.

The medium can now escape from the nozzle. When the signal on the pilot valve stops, the spray valve will
be closed (needle will be pushed into the nozzle).

The atomizer air divides the material into a spray jet and can be controlled through a 3/2-way magnetic valve
(not included in delivery). A short pre- or post-spraying can also be required. And a suitable device has to be
employed for pressure control.

When the control air is turned off or fails, the needle spring will close the spraying device.
The medium itself is supplied to the valve from a pressured container or via a pump.

5 Mounting and First Start-up

The SMS-22 Spray Valve can be installed in any position.
The distance to the application area depends on the desired application width. The larger the distance of the

nozzle opening to the application area, the wider will be the actual application of material.

An intermitting operation of the device will cause natural oscillations; therefore a solid installation is most
important. Try to avoid excessive natural oscillations (transmission from device to valve).

5.1 Hose Mounting

There are three functional hoses for the supply of compressed air and material to the spray valve; they which
will be connected as follows (see figure on following page):

 Atomizer air (blue)

Connection ZL: to 2/2-way magnetic valve

 Control air (black)

Connection SL: close control air to 5/2-way magnetic valve

 Control air (black)

Connection SL: open control air to 5/2-way magnetic valve

 Material (transparent or white)

Connection M : to pressured container or pump

 Unscrew safety cap from connection neck and slide over hose.
 Place open hose end on the connection neck.
 Put safety cap on connection neck and re-screw tightly.
