ROTARY AIRLOCK, PROVIDING A WAY OUT. Let us guess, you've got a line down again, and even though you have multiple production lines that all use 10" rotary valves, you can't swap one or use a spare from any other line because...they are different OEMs and they don't fit. Really? They're all the same size though right? Wrong. Each OEM may carry a 10" valve but guess what? They specifically make it a different height so no other valve can take its place so you HAVE to go back to the original OEM for replacements & spares. Running up your inventory and getting pressure from the brass to lower your spending. You would if you could, right? ​ Rotary Airlock's Cross-Fit is the answer.​ ​ Rotary Airlock is the only manufacturer who can take 3 different OEM models with the same bore size and engineer, and successfully produce a replacement valve that fits all 3 heights. With a Rotary Airlock Model and pan head-mounted flange adapters, we can customize your airlocks to fit all of your production lines without running up your inventory and providing the convenience of swapping valves in down lines in a matter of minutes, or hours instead of days or weeks. We even provide the drive and speed switch in case your lines run at different RPM so you can adjust your valve to operate specifically for you and your application. ​ Break free of the stranglehold of the other OEMs and give us a call today at (815) 564-1729. With Rotary Airlock, it'll be YOUR airlock solution. Guaranteed. CALL NOW! ALL THIS INVENTORY JUST THIS Different valves, multiple bearings, additional packing sizes, that can't be swapped between OEMs, or... 1 Valve for Multiple OEMs | 1 Bearing Style | 1 Seal Solution CALL NOW!

for ANY Ethanol Application SDO-71 Valve (Replaces KICE Valves) for ANY Ethanol Application SDO-120 Valve (Replaces ROTOLOK Valves) ...ESPECIALLY ETHANOL A MASTER CLASS VALVE ALL ITS OWN If we've said it once, we've said it a thousand times, other OEMs build their valves to fit their SYSTEMS not to fit your APPLICATION. The ethanol industry gets hit with the brute honesty of this statement more than most. No matter what type of system you have, corrosion, failed seals, and broken braces are a constant struggle the Ethanol Industry faces. ​Some original valves see SO MUCH corrosion they may as well be a chute. These same valves are configured with product facing seals that CONSTANTLY fail, and fail, and fail. Why would you provide a valve, cast from the wrong material for the application, and with seals that are explicitly designed for industries other than ethanol? ​Let's not forget the chemical processes of ethanol being time and environment-sensitive, have NO ROOM for downtime. So why do some Ethanol valves have lead times that are MONTHS!, and that's for the same FAILED configuration! ​ ​ A Cut Above the Rest Rotary Airlock has specifically poured their efforts into alleviating the struggles the Ethanol industry faces. We have engineered, tested, and implemented hundreds of valves SPECIFICALLY for ethanol applications. ​ With all-new stainless steel rotors, stainless steel wear plates, and chrome housings, corrosion NEVER stands a chance. ​ We even replace those product facing seals and give you nothing short of the industry's Master Class outboard seal & flange bearing where both can be changed IN-LINE in less than 15 minutes. Rotary Airlock's Ethanol Package applied to your valve makes it truly a Master Class valve all it's own. So when it comes to expert knowledge, the right products, and correct application, there is only one choice, Rotary Airlock, especially when it comes to ethanol. STAINLESS STEEL ROTOR Corrosion doesn't stand a chance. Used in moderately corrosive applications and/or those designating a need for food-grade quality. ​ Corrosion-resistant 304L Stainless can be found throughout your entire valve but especially your rotor configuration. FULLY FABRICATED BRACES Fully fabricated, NEVER cast. Our valves are fully fabricated for strength and reliability and never cast. ​ So you won't have to worry about snapped braces, fractured housings, or cracked endcaps throwing your rotors our of spec. and destroying bearings. RAPID ACCESS ENDCAP Change seals & bearings, IN-LINE. In less than 15 minutes, you can change our proprietary MAP Seal and piloted flange bearing all In-Line. ​ No need to pull an airlock means less downtime, less labor, and more product & profit for your bottom line. MADE IN AMERICA Made right here in the heart of USA. We are an American company, providing for American families. ​ Located here in the heart of the USA, we know how important quality and reliability are, as well as lead times so quick we want them to have their own express lane.

WHY DIRECT DRIVE? THE HIGHEST SAFETY STANDARD Chain driven valves carry open chain guards allowing hands, clothing, shoelaces, debris, etc to access moving chains, shafts, and sprockets. Those chains and sprockets require a lubricant too that must be applied from under the open chain guard, dangerously requiring hands and fingers close to moving parts at an unsafe & unstable angle. ​ With unfinished, jagged, & sharp metal edges (at an exact point where hands/fingers are required to work no less) and a required mounting table which increases materials, and therefore the valves, costs and maintenance issues, chain driven valves hold immediate safety hazards and higher costs. ​ Speaking of higher costs, they require you to store sprockets, chains, repair parts & tools, additional lubricants and more on hand. These all inflate and eat into your maintenance & inventory budget and ultimately, your bottom line. BREAK THE CHAIN! *see what we did there ;) Without extensive access to moving parts like chain driven valves have, Direct Drives eliminate possible hazard points and lowers the possibilities of injury during operation & maintenance. ​ With a direct drive, there is ZERO need for additional sprockets, chains, repair parts, and...well, you get the point. ​ There's no need to diminish your maintenance & inventory budget and keeps the costs from job site accidents out of the equation, ultimately, increasing your profits.
