Controller (VXFC06D) VXF2�ｮ�ｮ Air tank Vl Piping length Controller (VXFC06D) Pilot valve (VX232AA) VXFA2�ｮ�ｮ Air tank Vl Piping length Piping length 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, response delay of valve, malfunctions or oscillation may occur.
