The Model VLP-24 MagnaValve is a normally closed valve used to regulate steel shot
or grit in wheel blast systems. The valve is constructed with a permanent magnet to
hold media until power is applied. An electromagnet cancels the permanent magnet
and allows the media to flow at a controlled rate. A desired flow rate may be achieved
by regulating the voltage to the electromagnet.

The VLP-24 MagnaValve can be used in manual or automatic mode. In manual (or
open loop) mode, a model Pot-24 is used to adjust the flow rate. For automatic (or
closed loop) operation, an AC-24 Shot Flow Controller will detect the load placed on
the Wheel motor and regulate the flow of media. This closed loop system will provide
accurate and repeatable flow rates over a 200 -1000 pounds/minute flow range.

The valve must be operating with an AC-24
Control for amperage closed loop feedback.
Open loop control (Pot-24) will not provide
linear regulation.

MODEL VLP-24 MagnaValve

Note: Do not restrict the media flow above the MagnaValve as this will reduce the protective “shot
blanket” on the pole pieces. Without the protective shot blanket erosion will occur, reducing the product
life span. The valve should also be mounted in a horizontal plane within 5°.

Note: for best results connect 24 Vdc power supply first to the MagnaValve and then to the controller.
This reduces the voltage drop caused by the valve current. See application note AN-168 and AN-169
for more information on wiring connections. All additional wiring should be in private conduit shielded
from motor wires.
