The ACS MD Series rotary airlock valve comes with a rail that reduces material buildup in pneumatic conveying systems. Its design isolates the bearings from blow-by and damaging materials or contaminants, and protects the bearings in applications up to 500°F. The valve is available in sizes from 6 to 22 in. Rotor configurations include closed end, metering, Teflon coated and adjustable tip.
