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
4.1 Purpose of the Incomplete Device
The MPP-03-PRO Micro Point Pulse Valve is a pneumatically controlled application device designed for the
application of materials such as sealants, adhesives, greases, paints, oils, etc. The needle piston is alter-
nately impinged on by air, triggering an opening and closing of the needle. If the control air is cut off or fails,
the spring closes the needle. The medium is supplied to the valve either out of a pressure tank or a pump.
The valve discharges a full jet depending on the individual nozzle size.
MPP-03-PROs are extremely fast switching valves. The valves will be predominantly used for the application
of greases, sealants, adhesives and oils. Depending on the nozzle size, media with different viscosity can be
processed. MPP-03-PRO valves are high-precision tools with a long lifetime if the below mentioned instruc-
tions are strictly followed.

4.2 Type Label of Incomplete Device
The type designation is etched in close to the material connection.
The serial number is also inscribed in this area.
5 Start of Operation
5.1 Mounting and Installation
The valves can be installed in any position. The distance to the surface to be applied with the medium
depends on the spray pattern.
Vibrations of the valve caused by fast intermitting cycles require solid and tight installation. The device body
comes with two borings of 5mm diameter which were provided for a solid installation. Machine vibrations to
the valves should be avoided.
5.2 Hose Mounting
The two function hoses are to be connected as fol-
lows:
1 Control air connection to M5 connection (4.0)
2 Material connection at valve body is 1/8“ fe-
male thread.
5.3 Adjusting the Incomplete Device
The amount of material can be regulated via the stroke adjustment of the needle (7.0). A left turn of the regu-
lating knob increases the material amount. A fine precision thread affects a needle rise that results in an
adjustment of 0.5mm with each turn of the adjusting knob.
IMPORTANT
Do not exceed the maximum turn counter-clockwise of the raster needle locking screw (no
more raster steps noticeable). By then the maximum needle stroke regulation has already
been exceeded.
If you continue turning, the raster needle locking screw will dislocate and jump out!
IMPORTANT
Nozzle and needle can be damaged by wrong handling. Only decrease the material flow by
a right turn of the regulating knob.

5.1 Raster-Needle Sensor
Optionally, you can use a raster-needle lock with a pre-installed, inductive proximity switch. It will release a
signal when the needle piston with the needle is open. This will help you in digitally monitoring the status
„nozzle open“.

6 Operation
6.1 General Information
The incomplete 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
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 pro-
tection should be worn, if required.
WARNING
Danger caused by flammable, harmful fluid. Always follow the safety instructions on the con-
tainer or the safety data sheet for the fluid.
The MPP-03-PRO Micro Point Pulse Valve usually works with a control air pressure of 5 –6 bar and material
pressures of up to 100 bar. To obtain a consistent application pattern, the air supply must be kept constant
without any fluctuations.
IMPORTANT
Accident prevention directions will be strictly followed when applying high material
pressures. Please strictly follow the following instructions when planning and constructing
application systems!
The valves are suitable for contactless and regular application and can be controlled for intermittent or con-
tinuous use. According to the individual application, the control air must be adjusted to the operating cycles
and to the higher or lower material pressures. 200 tacts per second can be reached under appropriate oper-
ating conditions (material pressure, control air pressure, needle stroke, and short conductions).
The amount of material can be regulated via the stroke adjustment of the needle. A left turn of the regulating
knob increases the material amount. A fine precision thread affects a needle rise that results in an adjust-
ment of 0.5mm with each turn of the adjusting knob.
IMPORTANT
A plant-specific setting is required for an optimal adjustment of the application pattern. Start-
ing values from laboratory tests can be used as a basis. However, these may need to be
adjusted for the specific plant. A combination of the following parameters is necessary: noz-
zle size, opening time, opening stroke, material pressure and temperature (if applicable).
It is harmless to leave fluid in the valve during longer standstills if system stays under pressure (no connec-
tion to outside air).

7 Maintenance and Repair
7.1 General Information
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.
The MPP-03-PRO Micro Point Pulse Valves are high precision tools. Always keep clean and observe mini-
mum instructions to maintain a long life of the valve. We recommend lubricating moveable parts regularly
and greasing threads, especially the nozzle threads, when replacing or cleaning the nozzle. Always use
clean and filtered material only. The control air must also be clean and should be slightly oiled, if necessary.
Maintenance also depends on the individual operating conditions and the type of media used.
7.2 Cleaning
IMPORTANT
Only use soft brushes for outside cleaning of the nozzle tips. Never use metal tools with
sharp edges.
Wash incomplete device thoroughly after use to remove residues and dirt, especially, if needle (7.0), sealing
screw (6.0) or nozzle (1.0) have to be exchanged.
7.3 Replacing Needle (7.0) and Nozzle (1.0)
Completely unscrew raster needle lock (9.0) and nozzle (1.0). Pull out needle spring (8.0) and carefully push
out the needle (7.0) towards the nozzle end. Slightly grease replacement parts and re-assemble them in
reverse order. Do not reuse old needles. Even slightly dirty needles and needle shafts can cause leakage in
the special form gasket (5.1).
7.4 Replacing the Sealing Screw (6.0)
Completely unscrew raster needle lock (9.0) and nozzle (1.0). Carefully push out the needle (7.0) towards
the nozzle end. Then unscrew the sealing screw (6.0) from the thread with a screwdriver. Since the outer O-
ring (6.2) prevents the sealing screw from falling through the mounting thread of the valve body (3.0), it is
necessary to push the sealing screw together with O-ring (6.2) carefully backwards through the thread using
a thin strip of metal (0.5 –1.0 mm) which you push between the recess in the body and flat in front of the
front end of the sealing screw. You can then take the sealing screw out of the enclosure.
7.5 Inserting Gaskets and O-Rings:
If a complete sealing screw (6.0) with an inserted gasket set (5.0) is not available as a replacement, the old
gaskets must be removed and replaced with new ones. In order to do so, the sealing screw must be thor-
oughly cleaned so that no particles of the previous spraying fluid impair the installation of the new gaskets.
The O-ring seats should be lightly greased with a lubricant (technical Vaseline). First insert O-ring (6.2) into
the rear hole of the sealing screw until it reaches the end. Then insert O-ring (5.2) into the outermost groove.
Insert the special form gasket (5.1) into the front seat. Since this form gasket is not symmetrical, the side
with the larger outer diameter must be inserted facing forwards, i.e. it must point in the direction of the nozzle
after the complete sealing screw has been installed. Lightly grease the sealing screw (6.0) and insert it back
into the valve body (3.0). Use a screwdriver to carefully push it through the mounting thread together with the
outer O-ring (6.2) without twisting it. Then screw the sealing screw into the thread (gently tighten).
Do not use any metallic or sharp-edged aids or tools when you insert the O-rings and the special form gas-
ket. Despite all its outstanding sealing qualities, the special form gasket is a sensitive precision component,
which cannot tolerate impacts or pressure
