When you’re running a bulk material handling system, every component plays a role in your bottom line. However, when it comes to system flow, contamination risk, and maintenance downtime, your diverter valve is a game-changer.
Whether you’re handling powders, grains, or abrasive minerals, the right diverter valve doesn’t just direct material—it protects your entire operation from costly errors.
So, how do you decide between a clean flow diverter and a rugged traditional design?
In this post, we take a closer look at Roto-Disc® clean flow diverters versus traditional diverter valves—breaking down the differences to help you choose the best fit for your system, materials, and operational goals.
What Is a Clean Flow Diverter?
A clean flow diverter is engineered with hygiene, ease-of-maintenance, and precision in mind. Roto‑Disc’s clean flow designs, like the Roto‑Blade™, feature smooth, full-bore interiors and minimal dead zones to reduce residue buildup.
These diverters are ideal for:
- Food and beverage dosing lines with allergen sensitivity
- Pharmaceutical or nutraceutical powder blending
- Specialty chemical systems that switch between products
- Any system requiring fast, compliant cleanability
Why choose Roto‑Disc’s Heavy-Duty Clean Flow Diverter?
- Designed for clean-in-place (CIP) compatibility
- Smooth surfaces promote flow and reduce bridging
- Sanitary interior geometry speeds validation and cleaning
- Built with durable materials suitable for fine or sticky powders
Traditional Diverter Valves: Rugged and Cost-Efficient
If your system is moving abrasive, high-volume materials, and sanitation isn’t your top priority, traditional diverter valves are often the most practical and cost-effective solution.
These valves are the workhorses of bulk material handling: less focused on cleanability, but unmatched when it comes to withstanding wear, tear, and pressure. They’re still a smart choice when:
- You’re conveying coarse or abrasive materials like aggregates, minerals, or cement
- Your process doesn’t require frequent product changeovers
- Sanitation isn’t critical (e.g., plastics, raw feedstock, or chemical pellets)
- Your team is balancing performance with budget-conscious decisions
Roto-Disc’s Heavy-Duty Spherical Diverter Valve is a prime example. It’s built to:
- Hardened components resist erosion from abrasive solids
- Simplified actuator options make installation easier
- Designed for long operational life in high-volume systems
Side-by-Side Comparison
| Feature | Clean Flow Diverter | Traditional Diverter Valve |
|---|---|---|
| Sanitary/CIP Capable | Yes | No |
| Ideal Materials | Fine powders, food, pharma, allergens | Abrasive solids, pellets, aggregates |
| Cleaning Frequency | Quick and easy to clean | Requires full disassembly |
| Maintenance Requirements | Low | Moderate to high |
| Best Used In | Multi-product lines, sanitary apps | Single product lines, rugged bulk systems |
| Example Roto-Disc Solution | Roto-Blade™ Clean Flow Diverter Valve | Roto-Vert™ Heavy-Duty Spherical Valve |
Valve Selection for Bulk Material Handling: How to Decide
When choosing between clean flow and traditional diverter valves, here’s what to prioritize:
- Sanitation Requirements: Clean flow is the solid choice if your process involves allergens, pharmaceuticals, or any other applications requiring compliance.
- Material Abrasiveness: Traditional diverters with hardened parts may be a better long-term investment for materials such as rock, minerals, or glass.
- Product Changeovers: If you switch products regularly, choose clean flow to reduce cleaning time and minimize contamination risk.
- Cycle Frequency: High-cycle environments require rugged reliability—both types offer this, but clean flow designs often last longer with less maintenance.
- Budget & Footprint: Traditional designs typically come in at a lower cost and are simpler to install when space is tight.

Engineering Insights: Wear & Diverter Valve Design
According to Processing Magazine’s article “Conquering the Main Wear Factors in Diverter Valves,” erosion is a major failure mode in pneumatic and gravity systems, especially with abrasive powders.
We address this by:
- Using hardened materials (like tungsten-carbide liners) in wear-prone parts
- Designing inspection ports for easy maintenance without removing valves from the line
- Offering replaceable seals and wear components in our heavy-duty diverter series
These features help extend service life and reduce unplanned downtime in challenging environments.
