Valve Bag Fillers
Valve bag fillers load product through the valve opening of a multiwall bag. The valve closes after the bag fills, which keeps dust down and makes a clean, stackable package. The machine you need depends on the material to be packaged.
There are three feed types. Air uses blower air, impeller uses a spinning pump, and auger uses a screw. Each application suits a different machine.
Air Packers
Blower air feed for sand, dry mix concrete, mortars, granular minerals, fertilizer, and salt.

Impeller Packers
A spinning pump for cement, powder minerals, and non-sanded building products at high sustained rates.

Auger Packers
A screw feed for flours, spice blends, chemicals, feed supplements, and non-sanded grouts.

If you are not sure which one fits, start with your material. That decides more than anything else.
| Air Packers | Impeller Packers | Auger Packers | |
|---|---|---|---|
| Feed method | Blower air | Impeller pump fed by twin screws | Screw auger |
| Best for | Sand, dry mix concrete, mortars, granular minerals, fertilizer, salt | Cement, pulverized gypsum, sanded grout mixes, heavy bulk density powders | Flours, spice blends, feed supplements, plastic powder resins, non-sanded grouts |
| Typical speed | 4 to 12 bags per minute | 4 to 12 per spout, over 20 in multiple installations | Up to 4 bags per minute |
| Weight range | 20 to 110 lbs | 20 to 110 lbs | 20 to 110 lbs |
| Handles abrasives | Yes, the plug stack design is built for it | No, needs non-abrasive material | Only with a hard-faced stellite auger |
| Watch out for | Blower sizing on multiple spout lines | Requires a constant head of material | Slowest of the three |
| Models | 2010 PS, 4210, 4213 | 4010 | 4190 |
Choosing a Weighing System
All three feed types are available in stainless contact surfaces, and all three need the correct feed hopper to reach optimum rates and weight accuracy. Correct bag sizing and construction differ by style. The weighing choice is separate from the feed choice.
Common to All Valve Bag Fillers
- Mechanical scale weighing: less maintenance and faster production, generally less accurate than electronic
- Electronic weighing systems: more accurate but slower in bag filling and higher in price
- All three types require the correct feed hopper for optimum rates and weight accuracy
- Correct bag sizing and construction are different for each style
- All three available in stainless steel contact
Valve Bag Placing
Robotic Valve Bag Placer
Automatic valve bag placing to eliminate manual spouting of bags. Single and dual spout placers, placing up to 14 bags per minute.
Multiple Spout Operator Deck
For valve bag fillers in two, three, and four spout decks, with operator chair, empty bag racks, take away conveyor, and surge bins.
