Dedicated Controller For VXF(A)2/Series VXFC
A dual pulse function is adopted to improve the bag filter dusting
efficiency. Turn ON the DIP switch dual pulse (OFF for single pulse).
(Setting possible for all channels)
VXFC10: One board has a maximun of 10 outputs. But the outputs
can be increased to 20 and 30 by connecting multiple boards
(cascades).
Interrupting an operation from an external switch is possible using
input signals.

The valve characteristics data was measured with the stated outlet piping length. The valve characteristics vary depending on the
tank capacity, air supply, set pressure, outlet conditions (nozzle size, quantity, piping length), so please use these values as a
guideline.
Note) For air operated type, the longer the piping length to the pilot
valve, the longer the ON response time will be. If the piping
length is increase even more, the valve may not open due to
piping capacity and resistance in the piping, so keep the
piping length to the pilot valve as short as possible.

Note 1) If the regulator or the restrictor is installed right before the IN side of the
valve, the valve may oscillate when it is turned off. Keep the regulator or
the restrictor away from the valve for at least 1 m or change restriction.
Note 2) The dust collector valve is a large flow control valve in which air is
discharged with high speed to clean the bag filter with impact wave. Tank
capacity should be sufficient to secure impact wave and discharge flow
rate. If the air tank capacity is insufficient, increased response time,
malfunctions or oscillation may occur.
