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.

CAUTION

The use of other media can cause functional failures, damages or even the destruction
of the device.

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 sup­plied to the valve with a pressure of up to max. 150 bar via a high-pressure pump. Please contact the manu­facturer, 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

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.

4.2 Technical Data

General Data

Dimensions [mm] = ca. 44 x 25 x 25 (without connections)
Weight [g] = ca. 150 (with bracket ca. 185)

Energy Supply

Control air pressure [bar] = min. 3.5 – max. 6
Spray air pressure [bar] = should correlate to the material pressure
Material pressure [bar] = max. 150 bar (with air support, i.e. two air connections will be

used)
= max. 120 bar (without air support, i.e. only one air connection is
used)

The type label was etched into the casing near the material
connection. The serial number is also hammered into this la­bel.

4.3 Type Label

5 Installation and Start-up

The valve can be installed in any position. A special bracket is also available for a fixed installation (option;
see drawing). The distance to the application area depends upon the desired application width.

During intermittent operations, the device will produce own vibrations. Therefore make sure that the device is
firmly installed. Make sure you avoid extremely high vibrations (can be transferred from device to valve).

5.1 Hose Mounting

Three functional hoses will be mounted as follows:

• Control air (black)
Connection (13): to 3/2-way magnetic valve

• Control air (black)
Connection (13): to 3/2-way magnetic valve

• Sprayed medium (transparent or white)
Connection (14): to pump

CAUTION

Never point the jet at people. The wearing of eye protection is strongly recommended.
The spraying process can create noise depending on the air and fluid pressures used.
Ear protection should be worn, if required.

WARNING

Danger caused by flammable, harmful fluid. Always follow the safety instructions on the
container or the safety data sheet for the fluid.

IMPORTANT

In case high material pressures are required, make sure that the accident prevention
regulations of the trade associations will be strictly followed!

Important

The maximum material pressure will be 150 bar. It must in no case be exceeded.
Please contact the manufacturer, if you have to work with higher pressures.

6 Operation

6.1 General Information

This device may only be operated if the safety-related equipment is permanently effective and not suspend­ed during operation or altered in its intended effectiveness.

6.2 Operation Instructions / Operating Conditions

As a norm the Airless-Spray Valve SMS-13 operates with a control air pressure of 6 bar.

The application can be controlled as intermitting or continuous. Depending on the individual use, the control
pressure has to be adjusted to the set switching frequency on the one hand and to the higher or lower
material pressures on the other.

For longer standstills, the material can remain in the valve, if it remains under pressure (no contact to outside
air).
