Valve Bagging Machines
Precisely fill valve bags with powders, pellets, flakes, granules, and fibrous materials.
Valve bagging machines (sometimes called spout baggers) have a spout that is fully enclosed when filling through a "valve" on a paper or plastic bag. Valve bags are self-sealing or self-closing and do not require a bag closing heat sealer or sewing machine. This minimizes product spill and dust emissions resulting in a much cleaner work environment. This can also eliminate the need for a bag sealing or sewing machine. There are four main types of valve bagging machines including air, auger, impeller, and gravity-fed. The filling process can be manual, where an operator places a bag on the spout, or it can be fully automated using a valve bag placer machine.
These machines fill valve bags at rates up to 12 bags per minute, or 720 bags per hour. The filled bags typically weigh 20-110 pounds or 9-50 kilograms and can contain flakes, powders, or granular types of products.

Available Models
Auger Packer
An auger precisely conveys materials such as dusty powders, powder + granular mixes, and semi-free flowing into a valve bag. These types of valve bagging machines are automatic electronic scale gross weighing fillers that simultaneously fill and weigh product directly into valve bags.
Fill rate:1-5 bags per minute
Accuracy:+/- 0.5-1% of target weight
Bag weight range: 20-110 pound bags (9-50 kilograms)
Bag types: paper, plastic, and poly-woven valve bags
This machine bags hard-to-handle powders, flakes and granules. Example products can include:
- Sanded Cement Mixes
- Flour
- Chemical Powders
- Bakery Mixes
- Diatomaceous Earth
- Guar Gum
- Pigments
- Rice Hulls
- Cocoa Powder
- Cottonseed Hulls
Control Air: 80 PSI required at 1CFM per bag fill cycle (base model does not require air)
Electrical: 110 volt / 3 phase / 60 cyle

Air Packer
This type of valve bagging machine packages materials such as fine powders, powder + granule blends and granular products that are not heated, ground, or crushed into a valve bag. Product flows by gravity from a supply hopper bin into the air pressure chamber. Air pressure pushes the product into the bag. These machines are automatic electronic scale gross weighing fillers that simultaneously fill and weigh product directly into bags.
Fill rate: 1-12 bags per minute
Accuracy: +/- 0.5-1% of target weight
Bag weight range: 20-110 pound bags (9-50 kilograms)
Bag types: paper, plastic, and poly-woven valve bags
This machine bags materials with positive flow characteristics such as flaked, powdery and / or granular products. Examples can include:
- Concrete
- Stucco
- Grout
- Sand
- Refractory Materials
- Bentonite
- TIO2
- Iron Oxide
- Carbon Black
- Plastic Pellets
- Fertilizer
- Seeds
- Sodium Bicarbonate
- Control air: 80 PSI required at 1 CFM per bag fill cycle
- Electrical: 110 volt / 3 phase / 60 cyle
- Dust collection: 600 CFM minimum

Impeller Packer
A specially designed vertical or horizontal blade impeller conveys or "blows" materials such as fine, free-flowing powders with high bulk densities (50-100 pounds per cubic foot) into a valve bag. Material flows from a hopper by gravity into the machine where the product is conveyed by opposing twin screws into the impeller that conveys the material into the bag. These types of valve bagging machines are automatic electronic scale gross weighing fillers that simultaneously fill, and weigh product directly bags.
Fill rate: 1-8 bags per minute
Accuracy: +/- 0.5-1% of target weight
Bag weight range: 30-110 pound bags (13-50 kilograms)
Bag types: paper and plastic valve bags
These machines can bag fine powders with mid-ranged to high bulk densities. They can also fill bags with free-flowing granular and pelleted materials. Examples can include:
- Portland Cement
- Mortar Mixes
- Stucco
- Grout
- Gypsum
- Barite
- Light weight cement mixes (vermiculite, polystryrene)
- Kaolin clay
- Silica
- Graphite
- Carbon black
- Organic pigments
- Oat and rice hull ash
- Control air: 80 PSI required at 1 CFM per bag fill cycle
- Electrical: 220 volt, 380 volt, 440 volt / 3 phase / 60 cyle
- Dust collection: 600 CFM minimum

Automatic Valve Bag Placer
This machine is designed to automatically place and fill both paper and block bottom plastic valve bags. Bags enter the machine via a bag indexing conveyor. Each bag is pre-opened and tested before a placing arm secures the bag and delivers it to the filling spout. Filled bags are automatically discharged to an integrated conveyor to be taken to a robotic bag palletizer.
Bag placing rate: up to 12 bags per minute
Bag types: paper and plastic valve bags
- Control air: 80 PSI required at 1 CFM per bag fill cycle
- Electrical: 220 volt, 380 volt, 440 volt or 575 volt / 3 phase / 60 cyle
- Dust collection: 600 CFM minimum
