Headers | Harvesting | Products | Case IH

Designed to cater for high yield conditions

The corn headers are designed to handle increasing corn yields and tougher corn plants. With the increased productivity of the Axial-Flow® combines, the double roller chains run in an oil bath, to operate the row units in 8 and 12 and 16 row corn headers. It gives them the ability to handle the toughest and heaviest crop conditions at the maximum reliabilty. The row unit gearboxes themselves are a heavy-duty design, with the main gear box housing made from aluminum for reduced header weight. All row units are slip clutch protected and run in an oil bath for quiet running and high reliability.

Chopping ability

A perfect chop is essential with corn stalks, speeding up and enhancing their decomposition and preventing stalk borer pests from overwintering in the crop. With the header the corn plants are pulled down by high speed stalk rollers fitted with hardened knives, to ensure a proper grip on the plant to prevent the straw from entering the combine. Optional stalk choppers are available for each row, chopping the stubble close to ground, and to chop the straw pulled down by the rollers. The chopped straw is spread evenly over the rows for fast decomposition. The choppers can be engaged or disengaged separately for every row when the header is used in very stony conditions.

Simple servicing

Simplicity is key when it comes to servicing. On series headers the row unit dividers can easily be opened one handed, with gas struts providing assistance. Every header also comes with a spring tension release tool for removing the gathering chain. To move quickly from one field to another without leaving the comfort of the cab, both six- and eight-row headers are available in a foldable configuration.

High-speed, low-loss harvesting

The design of the Case IH grain header adapt to all conditions to extract the maximum from every field and every crop for the ultimate in high capacity, high quality harvesting. With its high sickle speed of 1,300 strokes per minute and its contour hugging ability the header maintains a consistent short or long stubble height, at a high ground speed. The integral knife drive pulley flywheel is designed to maintain knife inertia and to cut out peak loads, providing smooth running at any harvesting speed. The reel is synchronised with the ground speed, with automatic reel speed control, reacting to the combine’s forward speed to provide low-loss intake and top quality output.

Managing all conditions

The full capacity of the grain header can be exploited whatever the straw volume of the crop in question, with the aid of a movable knife that allows long-strawed crops and high volumes to be easily ingested for even and consistent feeding. For short crops the knife can be quickly retracted on the go, without reducing ground speed. A large 107cm reel diameter with exceptional lift height of 184 cm (approx. from the ground level to middle of the reel) makes it easy to limit losses to a minimum and reduce reel wrapping in crops such as canola and rye.

Don't bother with layed crops

grain headers are superbly equipped to deal with laid crops. Lifters can be set to reach below the cutterbar to ease the crop from the ground and improve cutting performance without picking up stones or loosing valuable ears. Lifters are available for conditions requiring them, such as flattened straw or over-ripe barley, while for circumstances where they are not needed, they can be stored in a convenient location on the right hand side of the header.

No grain loss

Case IH engineers have worked long and hard to minimise every possibility of seed loss at the header. The effective design of the poly crop end dividers gently presents the most down and tangled crop to the reel and cutterbar while positively following ground terrain. Reel options include plastic tines, recommended for most crop types and conditions, or steel tines, for demanding work such as thick, tough and laid crop. With the reel design and gentle crop engagement of the six bar reel, effective feeding and cutting, resulting in increased crop quantity and quality, are guaranteed.

Even feeding in all crops

Smooth, even crop feeding is guaranteed by the stainless steel auger floor, while the profile from the cutterbar to the auger floor is designed to ease the flow of crop into the auger trough. The auger is protected by a slip clutch and is driven by a heavy duty drive chain to ensure long life and positive drive even in tough crop conditions. It gently conveys the crop from cutterbar to the feeder, while an integrated grain saver prevents valuable crop from falling back to the field.

Floating over the ground

To follow ground contours as closely as possible and capture the best crop quality without soil contamination, the header features a wide range of adjustable elements. The cutterbar incorporates a fully adjustable suspension system designed to follow constantly changing ground contours in the most adverse harvesting conditions. It’s the key to full harvesting efficiency in every soil type, from soft to hard, dry or muddy. As an option, the TerraFlex torsion block - the heart of the header - can be controlled from the operator’s seat to adapt to field conditions. The skid shoes are designed to float softly on the ground, even in soft soil conditions. The Flex header can be used in rigid mode to harvest other cereal crops.

Not all rotary valves are designed to be interchangeable between ingredients, but ACS Valves has options for plants with split conveying feeds or multiple ingredients. The Multi-Port valve is one to consider, since it features multiple separate compartments in a single valve, making it easier to convey materials from different lines into a single valve. Many of our customers also use the Quick-Clean valve to convey multiple ingredients, because it can be cleaned and sanitized quickly thanks to its rail-based design.

Rotary valves can be very effective at minimizing leakage when properly configured by an expert.

As a general recommendation to prevent dust leakage, valves should be equipped with ACST-4 shaft seals and an outboard bearing design. You should also check rotor-to-housing tolerances often, as enlarged tolerances can also cause leaks.

Capacity is the volume of material your rotary valve can handle per rotation. The calculation involves the rate of conveying, material bulk density, valve efficiency, and RPM of your rotor. We can help you with the math, but if you're just looking for a valve sizing recommendation, you can use our handy calculator tool.

It depends! Do you want a valve with an easy-to-clean design? A valve with multiple ports for split conveying lines? Maybe a valve for heavy-duty applications, for corrosive material, or for metering small batches?

We could go on, but the best way to determine which valve you need is to speak with an ACS Valves rep. Give us the details and we’ll help you choose a rotary valve that’s optimized for your needs.

Because rotary valves come in so many different types and sizes, we don’t list prices online. Please contact an ACS Valves rep to request a quote. We’re happy to walk you through exactly what you need and why.

There are so many! Our standard CI Series valve is popular with its efficient construction and plenty of customization options. But there are dozens of other options, and they depend on:

1. Your application (e.g., construction, pet food, or cannabis processing?)
2. Your material (e.g., cement, plastic, or flour?)
3. Your system (bulk material, dust collector, or pneumatic conveyor?)
4. Your desired valve type (airlock with metering, metering/feeding, or airlock?)

You could go even further down the rabbit hole and customize valves with different rotors, coatings, and accessories for maximum efficiency. The easiest approach is to contact an ACS Valves rep to discuss your options — we’ll only recommend what your process actually needs.

This is a great question because they’re also called airlocks (or rotary airlock valves, or rotary airlock feeders) — just to make it extra confusing. The catch-all term is rotary valve, which is what we use most often.

The exact term changes depending on how the valve is used. Anything with the word “airlock” in the name is used to maintain a pressure differential between two separate compartments. Feeders are more about controlling the rate of material flow from one place to the next. If a valve does both, you would call it a rotary airlock feeder.

At ACS Valves, we have a lot of multifunctional rotary valves that can serve any of these roles, as well as more specialized valves for airlock or feeding/metering purposes. If you’re not sure what you need, give us a call and we’ll help you figure it out!

That depends on you. Do you need to control the rate of material flow (feeder), maintain a pressure differential between compartments (airlock), or a combo of both (airlock feeder)?

Not sure? That’s okay — give us some details about your process needs, and we’ll make a recommendation.

Sometimes the rotation of the rotor is reduced due to an overload of material, or larger pieces of material being fed through the valve, jamming in the clearances. In this case, shear pin sprockets will shear the pin on the sprocket, reducing the risk of damage to the rotor.

Too much clearance between the rotor, endplates and or housing can result in air loss. Measure the rotor to endplate and rotor to housing clearances to confirm that they are an NFPA compliant 0. inches. If the clearance is larger than this, it might be time to replace your rotor, rotary valve, or have it sent back to ACS for a repair or evaluation. Make sure to stick to a maintenance schedule and check your clearances at least every three months.

The capped pipe is called a housing vent port. Rotor pockets can sometimes contain a volume of pressured air, which can impede material flow into the airlock inlet, reducing your efficiency. Also, in conveying systems that run at 6 PSI and higher, large releases of air up the return side of the airlock can cause pulsing in the material flow into the conveying line. Using a vent helps solve both of these issues, and is also helpful in improving your fill efficiency.

Shear protectors reduce the flow of material at the valve's inlet. Reduced flow allows for better pocket fill and also reduces the risk of product jams in your housing clearances–ultimately protecting your product from damage.
