Tips for NFPA compliance in your rotary valve and process

Hey material, meet our valves. We have our valves conveying so many different products that we’ve made a point of becoming experts on a wide-range of materials. But that’s just the type of company we are: Comprehensive and extremely helpful. This is how we make sure you’re producing high-quality products, every time.

Used on both ends of the rotor shaft for a tight seal. The option of air purge connections for severe conditions are available on either shaft seal, they help keep the material from building up around the shaft seals.

View the additional conveying equipment choices we offer to complement your rotary airlock valve.

Multi-compartment rotary valve for higher-volume applications or split-line conveying feeds

The Aero-Flow Series valves are built to application-specific requirements, including: custom rotor configurations, factory-applied internal coatings, and sanitary materials of construction.

The AN-X Valve is an NFPA compliant dust collector valve for any application. Complete with steel rotor tips and outboard bearings, this valve is great for easy, drop-in replacements for FT or AN dust collection valves.

The BT Series valves ensure optimal bulk density and throughput of hard-to-convey material; a return-side vent vents leaked air, maximizing air flow through the rotor, improving material flow.

Rotary Valve for Metering, Feeding and Airlock Applications.

Tool-less, single-step access to rotor and internal surfaces; simplifying cleaning, validation, and inspection.

The CI Series rotary valves are also available in sanitary 304 or 316 cast stainless steel models. Sanitary CI Series models also offer the ACS RotorRail™ quick-clean feature.

Rotary plug valve (RPV) design provides highly accurate, controlled feeding of very free-flowing, abrasive, and high bulk density materials; excellent dust control design.

The DC Series valves are built to application-specific requirements, including: custom rotor configurations, factory-applied internal coatings, and sanitary materials of construction.

For extremely high-volume material handling applications where short-length screw conveyors or conventional rotary valve material handling capacities are not sufficient.

For Feeding and Metering Applications. Pneumatic operation, ships ready for start-up, including: complete factory assembled solenoid valve, timer, filter regulator, flow control valve, lubricator, and regulator.

The DR-S Series valves are built to application-specific requirements, including: custom rotor configurations, factory-applied internal coatings, and sanitary materials of construction.
