When multiple ZP series vacuum pads are used with a single ejector, how does a ZP2V series vacuum-saving valve work to restrict the reduction of vacuum pressure of pads not in use?

Operating principle: The valve closes via air flow when it is not in contact with a workpiece, so the suction air can only flow through the fixed orifice.
At this time, an amount of air corresponding to the fixed orifice size is sucked in. When in contact with a workpiece, the valve opens and vacuum is generated.
In this way, this function restricts the reduction of vacuum pressure when some of the multiple pads are not in use.
