WHAT DOES A HOPPER TOP VALVE DO? “JUST PASSING THROUGH”

“I’ve got my ticket for the long way ‘round, The one with the prettiest of views; It’s got mountains, it’s got rivers, it’s got sights to give you shivers, But it sure would be prettier with you”

- Lulu & the Lampshades (aka “The Cup Song”)

When trying to design a pneumatic system be the most efficient and cost effective possible, sometimes it’s more about design than equipment.

A hopper top valve is a design to allow multiple fill points from a single source or bank of sources and then route the material back to a remote source. That’s a really fancy way of saying we can get rid of a whole bunch of filters and shorten your stack-up height.

At the heart of the valve is a standard butterfly valve, fitted for the application with a transition on top to fit a convey line running over it. When the valve is closed, material transfers right over it. Thanks to a resilient seal, with no leakage and minimum abrasion. When the valve is open, it provides a deflection to load material into the hopper while allowing a path down the back side for material to continue on (Making this the handiest little accessory since Gallagher brought us Sledge-O-Matic for Watermelons).

OK. Great. So what does that DO for me as a customer? I’m glad you asked…

By placing it onto a receiving hopper, a filter receiver assembly can often be eliminated. If said filter is say 304 stainless steel? This can often result in a savings of $5,000 -$30,000 PER DESTINATION!!! If you are, refilling, say…4 mixers? You can see the potential savings already. In addition, because you do not have need room for filter assemblies, stack-up height, often at a premium above process equipment, can usually be reduced substantially (typically by 4 to 8 feet).

Please keep in mind to examine the WHOLE system before installing one though. Care should be taken to make sure the receiving vessel/hopper and it’s discharge can stand the pressurization that going to happen as a result of the “looping” air.

And see? You didn’t even get any watermelon on you….
