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 alter­nately 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 instruc­tions are strictly followed.
