As product flows through your valve, some will make its way to the seal, degrading it over time, leading to catastrophic bearing failure. Our Solution: MAP SEAL SYSTEM Rotary Airlocks’ proprietary, food-safe seal mounts directly to the shaft and rotates with it to reduce wear and eliminate product migration. A 3–5 PSI air cushion above line pressure keeps product away from the bearing.

Most rebuilds just involve tipping the rotors and filling holes, which can reduce valve lifespan. Our Solution: Rotary Airlock restores them to like-new condition — EVEN BETTER THAN NEW — while offering solution options to extend your valve’s current life expectancy. Check out the video below to see the Rotary Airlock rebuild difference!

Your rotors and housings are under attack from corrosion and abrasion, reducing functionality, reliability, and life span! Our Solution: UPGRADED MATERIALS & COATINGS Abrasion-resistant options such as AR400, AR500, proprietary high-performance SERCON coating, and CERAMIC TILES provide exceptional hardness, wear resistance, and durability options, while stainless steel options can handle even the most challenging corrosive processes.

OEMs discontinue models that your process still needs. Forcing you to buy new systems or new valves that require changes to your transitions, costing you time and money, often without upgrade options. Our Solution: DROP-IN REPLACEMENT Rotary Airlock can provide drop-in replacements with the same height and flange dimensions for virtually any make or model used in your process. Through innovative technology, we are able to capture pertinent dimensions—or have those dimensions on file—to manufacture any make or model and provide solution options designed to extend your valve's lifecycle.

Most OEM valves are casted overseas and are reliant upon volatile supply chains that lead to extraordinarily long and unreliable lead times. Our Solution: FABRICATED IN USA Rotary Airlock produces valves from start to finish in the USA, allowing us to provide reliable lead times with rush options available.

Most castings cannot be easily adjusted to meet the standards and requirements that are needed for today's processes. Castings that were created in the 1970s may find it difficult to provide the solutions you need today. Our Solution: ROTARY AIRLOCK RAS Because we manufacture each valve specific to your needs, Rotary Airlock is able to offer valves with the most up-to-date solutions for your process.
