Vacuum Products – Vacuum Saving Valve
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.
ZP2V is a vacuum saving valve that when multiple vacuum pads are operated by one vacuum generator, and some of them are not holding the work piece, the reduction of vacuum pressure is restricted and the work piece can remain held by the rest of pads. When the work pieces have different shapes, the control circuit can be simplified. There is no need for switching operation when changing work pieces.
