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.

5.4 Adjusting the Device

IMPORTANT

By turning the regulating screw you can adjust the material amount to the individual require­ments:
Right turn:  decreasing the material quantity
Left turn:  increasing the material quantity

IMPORTANT

It is possible that the figures in this operating manual slightly deviate from the actual design
of the device. Nozzle and nozzle needle can be damaged by wrong handling. Never reduce
material quantity (right turn at the regulating screw) when no material is discharged. When
the nozzle is closed, do not attempt to turn the regulating screw further to the right.

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!

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

Spray valves of the SMS-22 series generally operate with a control pressure of 5 - 6 bar. The atomizer
pressure has to be lower than the material pressure in order to avoid a repulse of the material. Atomized air
pressure and material pressure should be closely correlated.

 The control air pressure should be set at 5 – 6 bar.
 The atomizer pressure has to be lower than the material pressure in order to avoid a repulse of the

material. Atomized air pressure and material pressure should be closely correlated. The atomizer air
will be controlled as follows: turn on before opening the needle and turn off after closing the needle
(guarantees broad maintenance-free operation).

 For longer standstills, the material can remain in the valve, if it stays under pressure and if there is

no contact to outside air (only colors, abherents and oils). The material pressure in the hose,
however, should be decreased for greases in order to avoid any bleedings (oil separates).

 Material and control air will only be used in clean, filtered condition. The control air should be slightly

greased when supplied to the spray valve/ spraying device.

The following will be observed for a long-term interruption of the device/machine:

 Depressurize material supply lines
 Take air cap (2.1/2.2) off and clean nozzle (3) with a special thinner and a soft cloth. Make sure that no

cloth fibers are left on the nozzle tip.

7.3 Shutdown of Device

The following is important for a shutdown of the machine / device:
 Clean spray valve with a special thinner.

CAUTION

Before starting any maintenance or repair work, ensure that all air-operated tools are
depressurized and disconnected from the air supply.
Before opening the spray valve it must be disconnected from the air and fluid supply.
Otherwise, ejected components can cause injuries.

IMPORTANT

Only use soft brushes for outside cleaning of the nozzle tips. Never use metal tools with
sharp edges.

IMPORTANT

Nozzle set = nozzle needle, nozzle and air cap (should always be replaced at the same
time)!

IMPORTANT

When installing nozzles and nozzle needles which have already been in use, rinse the noz­zle with a suitable thinner to make sure that no residues of material remain. Also the needles
shaft will be thoroughly cleaned from residual particles. Needle shafts with cured material
can cause damages at the sealing element.

8 Maintenance and Repair

8.1 General Information

The spray valves of the SMS-22 series are high-quality precision devices which will not fail if treated correct­ly and will operate almost maintenance-free. All mobile parts should be regularly oiled and also the threads
should be greased when the nozzles are cleaned or exchanged. Always keep clean and observe minimum
instructions to maintain a long life of the valve. Always use clean and filtered material only. The control air
must also be clean and slightly oiled, if necessary. Maintenance also depends on the individual operating
conditions and the type of media used.

8.2 Cleaning

Wash equipment thoroughly after use to remove residues and dirt, especially if the nozzle needle (Pos.12),
the sealing sleeve (11.3) or the material nozzle (3) has to be exchanged.

8.3 Replacing the Nozzle and Nozzle Needle

First take pressure off all connections and disconnect material supply! Loosen retainer ring (1) and remove
air cap (2). Loosen locking screw (6). Important! Carefully remove locking screw as it is under spring
pressure! Carefully pull out nozzle needle (5) from main body (4). Unscrew nozzle (3) with open-end wrench
SW6. Slightly grease new nozzle needle (5) and insert. Carefully wipe off grease from needle tip. Screw in
new nozzle (3) with open-end wrench SW6. Important! Always replace nozzle (3) and nozzle needle (5)
at the same time. Screw tight locking screw (6). Put on air cap (2) and tighten with retainer ring (1).

8.4 Replacing the Sealing Screw

IMPORTANT

Sealing and gaskets can be easily damaged. Therefore do not use any sharp-edged or metal
tools for removing and inserting the gaskets.

Take off pressure from all connections and disconnect material supply! Remove plastic sleeve (1). Loosen
locking screw (5). Important! Carefully remove locking screw as it is under spring pressure! Carefully
pull out nozzle needle (4) from main body (2). Loosen sealing screw (3) with a slot screwdriver and unscrew
from main body (2). Reassemble in reverse order.

8.5 Replacing the Sealing Elements of the Sealing Screw

Remove the old sealing elements (1,2,4) from the sealing screw (3). Carefully install the sealing elements
(1,2,4) with petrolatum on the sealing screw (3). Cover the sealing screw (3) with petrolatum so that sealing
elements will not be damaged when mounting the sealing screw in the main body.
