  • Product Adhesion Package | Rotary Airlock

    PRODUCT ADHESION (STICKY) No More Sticky Situations. Package Options key stressors key stressors key stressors key stressors PRODUCT ADHESION PRODUCT ADHESION STRESS ON THE DRIVE REDUCED THROUGHPUT Excessive stress on the rotary valve drive can increase friction and resistance, creating conditions that encourage product buildup and adhesion inside the valve. Product adhesion can reduce rotary valve throughput by causing material buildup on the rotor and housing. This limits product flow, making the valve less efficient and reducing overall production. As the product gets stuck inside a valve, it adds more stress to the drive, as well as limiting pocket fill. PRODUCT SOLIDIFICATION & ROTOR SEIZING When sticky product sits inside a rotary valve, it can solidify and build up around the rotor. Over time, this buildup can cause the rotor to seize, potentially leaving the valve unable to operate. Our Product Adhesion Package offers the specialized features and protection you need to minimize product buildup, improve material flow, and maximize valve performance. . . Radius Pockets Prevent material buildup and promote a cleaner release, especially when used in combination with an ENB™ coating. Long Running Valves Built with durable materials and precision to deliver long-lasting performance. Knife Edges The 1/16" landing allows the vanes to remove material more cleanly, cutting rather than pulling it away. Bearings Changable In-Line In less than 15 min per side , you change change our proprietary MAP Seal and Bearings systems in-line. ENB Coating ENB coating is utilized for its outstanding release capabilities, eliminating product adhesion.
