Abrasive materials pose some of the most difficult challenges for material handling systems, particularly rotary valves. Slowly but steadily abrasive materials scrape against the insides of the rotary airlock valves, leaving behind damage to airlocks and valves that may go undetected and cause major inefficiencies. As abrasive wear widens factory clearances, the seal of a rotary airlock valve can be damaged rendering it potentially useless. Yet all these factors still can’t eliminate the need for a valve in the system. A Rotary H Valve from Aerodyne is a great choice for systems requiring a positive airlock seal while handling highly abrasive materials. Specially designed for such occasions, the hardened tips of the Rotary H Valve’s rotor, as well as tight clearance in the H Valve’s casing, allow it to resist the wear and tear associated with abrasives. Aerodyne’s Rotary H Valve is a solid example of the design and durability required for rotary valves to solve tough material handling problems.
