Vacuum valve brings energy-saving benefits

Machine builders using vacuum for handling or pick-and-place applications now have an energy-saving option with the Series ZP2V vacuum saving valve.

Developed initially for the semiconductor market, these valves are designed to shut down the suction line when any leakage is detected from the vacuum pad not being fully aligned with the work piece or even when the work piece is simply missing.

By effectively stopping the air suction when the system recognises any irregularities, the energy used in making this vacuum is kept to a minimum. Without the need for a work piece detection mechanism - which often uses mechanical moving parts - unwanted surface scratches or marks on the work piece can be eliminated.

The valves can be used for either a standalone single vacuum pad or for multiple vacuum pad applications where the vacuum pressure loss is reduced to a minimum and the work piece remains held by the rest of the operating pads. Users will also save money and time by eliminating the need for expensive sensors or a programmable logic controller (PLC) and reduced labour costs when altering the control circuit to accommodate a different-shaped work piece.
