Piping example In-Line piping (VU or VUM) Type
Vacuum Pad
Vacuum Pad
Example 1 Example 2. Usage with Twin 3-way valve (SVA21).
Connect P Port and PD Port with Check Valve (Purchase separately).
The residual pressure between Check Valve and PD Port turns into a
blow- off air. The flow rate of the blow-off air is adjusted by a
release needle. Blow-off time can be controlled by the tube length
between Check Valve and PD Port.
Work-piece can be released instantly by adjusting a blow-off
pressure and a flow rate. But it is necessary to pay attention not
to blow away the work-piece. The above figure shows an example to
arrange the different pressure supplies to vacuum generation side
and Blow- Off Mechanism side when a blow-off pressure needs to be
controlled low (Pressure to vacuum generation side Pressure to
Blow-Off Mechanism side). A blow- off air is adjusted by the
release needle. Blow-off time is controlled by the solenoid valve
(SVA21 series).
