ANVER’s Automatic Flow Sensing Valves are an excellent choice when using large groups of vacuum cups where some may not fully cover a load. The sensing valves conserve vacuum for only the cups that are on the load. The more vacuum cups you have the more impressive the results. The closer to the cup the better they work as they have less air to evacuate and are faster to attach and release. The straight threads insure all the cups are at the same level, so you can use a few to hundreds of these sensing valves on a vacuum plenum. These valves may allow for a smaller pump to be used in many applications, which pays for itself.
- Spring-loaded float – engages vacuum seal and prevents vacuum loss
- Versatile orientation on cup or in-line
- Low cost
- Vacuum conservation using metered flow sensing technology
- Direct valve-to-vacuum cup mount
- Internal filter
Note: These cups are designed to not seal shut completely. This purposeful small vacuum loss allows the cups to have immediate vacuum when placed on a load.
These valves are for non- and semi-porous loads. An example of a typical application is handling a complete layer of cans from a skid layer where some objects may be missing occasionally. Other applications include:
- Plant operations
- Pick and place
Note: Do not use in dusty, dirty environments. Field-tests show that sensing valves are not suitable for dirty or dusty environments. Heavy stone dust, slurry, abrasives, or dusty wood can clog the valves. A blow-off system is helpful, but it will not ensure that heavy debris will be purged after each cycle. Using filters between the cups and the vacuum pump may be a better option for these types of applications. Call ANVER to learn more.
