MD Series with Quick-Clean RotorRail™ Rotary Valve for Metering, Feeding and Airlock Applications The sanitary MD Series valves, with ACS RotorRail™ quick-clean design, also have multiple Run-Clean™ features that reduce material buildup inside the housing during operation. Features & Benefits • Tool-less, single-step access to rotor and internal surfaces; simplifying cleaning, validation, and inspection. • 304 or 316 cast stainless steel valve housing. • RotorRail™ feature maintains rotor and endplate alignment during dis-assembly; ensures fast and accurate rotor and endplate re-alignment during re-assembly. • Available in 4 heights, from 10 5/8”H to 18 3/8”H; and 4 flange diameters from 4” to 18”. • CNC-machined components and housing provide precision tolerances; eliminates axial shaft movement, extends maintenance cycles. • Outboard bearing design protects bearings in hightemperature and high-PSIG applications; removes bearings from direct path of damaging contaminants. • Easily manages pressure differentials up to 15 PSIG. • Excellent performance in high-temperature applications up to 500°F. • Square inlet / outlet flange. • No. 4 finish on internal product contact surfaces of housing, and all rotor surfaces. • Interior coatings: hard chrome, tungsten, nickel, and epoxy. • Rotor types: closed-end, metering, shallow-pocket, adjustabletip, and Teflon®-coated. • Adjustable rotor tip types: hardened steel, stainless steel, and bronze. • Shaft seal types: ACST-4™ glandless Teflon® shaft seal, and packing gland. • Valve housing vent ports. • Shaft seal and rotor pocket air purge. • 6-vane, 10-vane, or 12-vane rotor. • 8-vane rotor with beveled tips and sides. • Custom drive packages. • Direct-drive motor package. • Application-specific accessories: blow-through adapter, shear plate deflector, surge hopper, motion speed switch assembly.
