In today’s industrial landscape, the demand for dependable, efficient, and safe material handling solutions is higher than ever. From food processing to pharmaceuticals, chemical manufacturing to bulk solids handling, companies rely on specialized components to ensure optimal performance and safety. Among the leaders in this space is DMN Westinghouse, a globally recognized manufacturer known for its high-performance rotary valves and diverter valves. When paired with compliance to NFPA 69, their rotary valves can accomplish what other manufacturers cannot.
DMN Westinghouse Rotary & Diverter Valves: Reliable Material Control
Rotary valves are critical in bulk material handling, providing controlled feeding and airlock functionality and diverters to direct material flow to different areas. These features allow for:
- Precise metering: Ensures consistent flow of dry powders, granules, and pellets.
- Airlock capability: Minimizes air leakage between systems operating at different pressures, enhancing efficiency in pneumatic conveying systems.
- Durability: DMN’s rotary and diverter valves can be built with wear-resistant materials for long-lasting service even in abrasive or corrosive environments.
- Sanitary designs: Options like the MZC models are designed for easy disassembly, meeting stringent hygiene standards in food such as USDA dairy and pharma industries.
- Versatile Routing: DMN diverters allow for switches in product flow to different destinations, supporting multi-line systems with minimal downtime.
- Dust-tight Operation: Essential for controlling product loss and ensuring containment of hazardous or combustible materials.
- Easy Maintenance: Many DMN diverters and rotary valves are designed for CIP, quick cleaning, and inspection, reducing downtime during changeovers.
NFPA 69 Compliance: Explosion Prevention Through Engineering Controls
NFPA 69 is the Standard on Explosion Prevention Systems, providing guidance on the use of isolation, suppression, and venting techniques in systems where combustible dust or vapors pose ignition risks.
DMN Rotary Values do not just meet NFPA 69 regulations; they redefine what is possible under explosion-tested conditions. These values are validated by notified bodies and are fully certified with NFPA 69 and ATEX 2014/34/EU.
What Does This Mean?
- Clearances up to 0.4 mm (0.016in) – This allows for valves to operate at much higher temperatures than before and still meet compliance. Larger valves, up to 20-inches, can also be used.
- Flexible Blade Options – This allows for the use of metal or polyurethane; scraper, chamfered, or knife-edge rotor blades.
- DMN Westinghouse Values are made with certified inboard or outboard bearing and function within NFPA 69 compliance at high rotor speed.
DMN Westinghouse provides peace of mind with their compliant valves which go above and beyond thus reducing the likelihood of catastrophic failure.
A Smart Investment in Safety and Performance
When it comes to choosing components for your material handling system, opting for DMN Westinghouse rotary and diverter valves is more than just a functional decision—it is a strategic investment in process efficiency, system longevity, and workplace safety. And when these components support or are part of NFPA 69-compliant systems, you are not just moving products, you are protecting people, equipment, and facilities.
Whether you are upgrading an existing line or designing a new system, consider how Dynequip’s creative designs, DMN Westinghouse products and NFPA 69 compliance can work together to keep your operations flowing safely and smoothly.
