DMN-WESTINGHOUSE ROTARY VALVES AND DIVERTER VALVES

January 16, 2025

Setting new standards for the dairy industry

Product quality, product safety. The guiding mantra in dairy production. That’s why the world’s leading dairy producers rely on the products and solutions developed by DMN-WESTINGHOUSE. Our rotary valves and diverter valves offer the highest level of precision engineering, preventing bridging and possible contamination during conveying processes. At the same time, they guarantee unparalleled cleanability, drastically increasing product safety while reducing downtime for maintenance and repairs.

Taking up the challenges

Through years of experience and valuable partnerships, DMN-WESTINGHOUSE has gained a deep understanding of the global dairy industry and its challenges. We have earned the trust of an industry where hygiene, cleanability, and safety are paramount. In our R&D department, we leverage innovative technology, setting the dairy industry standard. In our factories, we control every step in the manufacturing of heavy-duty rotary valves and diverter valves.

Always compliant

Just like you, we strive for unparalleled quality and consistency. A commitment underscored by our compliance with current certifications, including USDA, EHEDG-ED Class II and ATEX. Whether it’s about infant formula, lactoferrin, (plant-based) milk powders, caseinates or probiotics, at DMN-WESTINGHOUSE, we help you maintain the highest quality standards in dairy.

Heavy-duty, finest quality

Many producers of dairy products, ranging from baby formula to lactoferrin, rely on our renowned heavy-duty rotary valves. These valves come in two types and various sizes: the drop-through type (AL/AXL/AML) and the blow-through type (BL/BXL/BXXL). They comfortably comply with the stringent hygiene standards the dairy industry needs to maintain. All product contact surfaces consist of food-grade material, polished to perfection. They are all radiused and polished to an astonishing 0,8 μm Ra (150 grit), and the rotor vanes have precisely chamfered edges preventing the build-up of conveyed dairy powders.

MZC-series: standard for safety, hygiene and cleanability

Cleaning intervals will vary depending on which dry dairy substances are processed. To reduce cleaning time and resulting downtime, we developed the MZC rotary valves based on our AL— and BL-series. The MZC-I and MZC-II are equipped with supporting rails so the rotor and end cover can be removed. The MZC-II opens on two sides for unprecedented easy access and superior cleanability.

These valves facilitate premium process handling, raising the bar in cleanability, hygiene, and safety. The rotor body clearances are set automatically when the rotary valve is closed after cleaning.

Options for ultimate safety and reliability

Adding innovative solutions can take your dairy production to the next level.

We offer:

  • Rotor Interference Detection (RID 3.0)is our third generation, detecting unwanted contact between the rotor and body or end covers. This prevents major damage and provides insight into product contamination. RID 3.0 offers 50 times more accurate resistance measurement than its predecessors.
  • Shaft seal flow control boosts the reliability of our AL and BL heavy-duty rotary valve series even more. Precise flow control prevents the build-up of powder residue on the shaft seals, minimising the risks of seal failure, contamination, leakage, damage and downtime.
  • Rotary valves equipped with the Sanitary Air Seal (SAS) outboard bearing shaft seal minimise leak risks due to pressure changes inside the valve, thus maintaining the right airflow.

Cleaning-in-place (CIP)

For maintaining hygiene and preventing contamination, cleaning-in-place (CIP) is indispensable. CIP is about cleaning the interior of pipelines, valves, tanks and other equipment without the need for disassembly. In the dairy industries it’s a necessary, often automated method to maintain the highest levels of hygiene and prevent contamination.

Your perfect Niro replacement

Handling dry dairy solids is about maintaining the strictest standards and requirements 24/7. Are you currently operating Niro rotary valves needing replacement any time soon? Our NR347 rotary valves (NR = Niro replacement) match the outer dimensions of the Niro valves operating within your system, which means they are usually a perfect fit. The NR347 is based on our heavy-duty AL250 model and is made of stainless steel. Meeting all hygiene and safety standards, the NR347 will prove its value day in and day out.

Our diverter valves: boosting efficiency and hygiene

Diverging and converging powders or granulates is a daily routine in dairy production. Safety, efficiency and maximum hygiene are key. That’s why our 2-TDV, 3-TDV, M-TDV, and GPD diverter valves are very much in demand.

  • Our 2-TDV and 3-TDV diverter valves are designed for quick disassembly and streamlined distribution. The 2-TDV effortlessly handles two destinations, while the 3-TDV targets three.
  • The M-TDV efficiently handles the pneumatic transport of powders or pellets, diverging and converging flows to multiple destinations. Available in different sizes, offering up to 14 ports.
  • Our diverter valves are the perfect choice for systems needing regular, quick cleaning with minimal downtime.
