The helmet valve is designed to combine controlled dosing and high flow rates without taking up excessive space. Its compact design makes it easy to integrate into existing production lines without major modifications, particularly in processes involving the handling and transfer of powders or granules.
This combination of high flow rate, controlled dosing and compact footprint sets it apart from conventional dosing solutions, which often require a compromise between these three requirements.
How the Helmet Valve Works
At the heart of the valve, a helmet-shaped, welded pendulum assembly regulates product flow. It is housed in a fully sealed enclosure that contains the material throughout dosing — particularly important for powders and granules. The helmet is operated by a rotary actuator, ensuring reliable, accurate and repeatable dosing from one cycle to the next. Optimized geometry provides precise flow control even at high throughput.
In summary:
- Welded pendulum helmet — regulates material flow
- Fully sealed enclosure — contains the material
- Rotary actuator — ensures reliable, accurate and repeatable dosing
- Optimized geometry — maintains flow control, even at high rates
Sizes and Materials
tailored to your application
Each valve is sized to suit your process. A range of sizes is available to match your upstream and downstream equipment, required flow rate and installation constraints.
Three material options are available depending on your product and operating environment:
- Standard carbon steel
- Stainless steel — for food processing and chemical applications
- Abrasion-resistant steel — for highly abrasive or aggressive materials
