piSAVE sense


piSAVE sense, a flow control/check valve for suction cups. Available as an integrated option for Piab’s piGRIP® suction cups, the piSAVE sense can also be used as a stand-alone product for any type or brand of suction cup. Flow control/check valves are used for “object sensing” on flexible vacuum handling devices with a centralized vacuum pump. The valves allow several suction cups to miss (or partly miss) sheet(s)/object(s) and still maintain enough vacuum level in the system and also offer a fast-release or blow-off. Traditional flow/check valves for suction cups such as ball-seat valves have proven to be very sensitive to orientation and dirt. Piab’s new piSAVE sense valve has a new innovative reliable design. It works great in any orientation, even upside down. It is dirt tolerant and characteristically increases vacuum flow through the valve when vacuum level decreases to compensate for leakage therefore retaining high lifting force in the cups that are in contact with product. User benefits include reduced need of vacuum pump capacity as you only use cups needed for the task, lowering pump investment and energy consumption. Users also have the ability to build flexible lifting devices that can serve a variety of different size or shape panels/sheets. This eliminates the need for multiple lifting devices.
