The vacuum saving valve (ZP2V) is installed between the suction cup and vacuum source and will constrict when it is not holding a workpiece, only allowing suction air to flow through a small fixed orifice, acting as a flow control device. When the suction cup is holding a part, the valve will expand increasing flow to the suction cup. This feature will save time by not having to reconfigure or remove idle suction cups when not being used for different tasks.
