3 Transport
3.1 Packaging
The type of packaging will be selected according to the mode of transport. If not separately negotiated, the
packaging will be made in accordance with the packaging directive of company Walther Systemtechnik
GmbH. This directive complies with HPE Packaging Regulations.
3.2 Tasks before Transport
The following tasks have to be fulfilled before the actual transport.
Disconnect energy supply lines
Extreme care has to be applied when transporting the incomplete machine and its individual parts in order to
avoid damages from external impacts or careless on- and off-loading. Depending on type and duration of
transport, appropriate transport securing devices have to be used. The incomplete device itself will be ad-
justed and leveled by appropriate fastening elements.
4 Functional Description
The
MPP-Speed
Micro Point Pulse Valve is an incomplete, electrically controlled application device de-
signed for the application of materials such as greases, paints, oils, etc. If the power supply is cut off or fails,
the spring closes the needle. The medium is transported to the valve either out of a pressure tank or a pump.
4.1 Functional Principle
By using hard materials it is possible to achieve little opening strokes of only a few hundredths of a millimeter
in size. Also, an extremely high repeatability in the range of thousandths millimeters can be realized.
The MPP-Speed is electromagnetically operated. The medium flows around the nozzle sphere. The closing
spring acts on the mobile anchor with a valve ball. When there is a current feed through the valve coil, the
mobile anchor with the valve ball is magnetically pulled by the magnetic field of the stationary anchor. The
micro valve opens and the medium emerges. After pulsing, the nozzle is closed again by the closing spring.
