This new line of ACS cast iron rotary airlock valves features the ACS RotorRail™ that enables tool-less access to the rotor and all internal surfaces of the housing without time-consuming disassembly of the rotor, or the removal from service of upstream or downstream equipment commonly associated with standard valve configurations. The ASC cast iron rotary airlock valve with RotorRail™ has shown, when compared to bolt-together housing designs, to reduce rotor service cycle times by 78%; and, as a result, increase total process uptime by 18% during a typical eight-hour operating shift. The ACS RotorRail™ feature of these cast iron valves also ensures accurate rotor re-alignment during re-assembly; thus, eliminating axial shaft movement, bearing wear and seal leakage, and premature, uneven rotor vane wear.

The cast iron housings of these ACS rotary valves are cast in North America, and are CNC-machined to precise tolerances. The optimal inlet/outlet seal produced by these ACS rotary airlock valves is achieved using the standard, ACS Valves, 8-vane rotor design. The ACS Valves 8-vane rotor design eliminates excess pressure loss through the system, ensures cost-efficient upstream and downstream material management, and reduces process energy consumption. These ACS rotary airlock valves are available in sizes from 6 inches to 16 inches, with pressure differentials up to 15 PSIG, and temperature tolerance up to 500ºF. Rotor configurations include: closed-end, metering, shallow-pocket, Teflon®-coated and adjustable-tip. Adjustable rotor tips are available in stainless steel, hardened steel, or bronze. Interior surface coating options include: hard chrome and Teflon®.

Ideal for sanitary applications such as food processing, pharmaceutical processing and chemical or plastics applications, the Run-Clean™ Series of rotary airlock valves are designed with multiple features that reduce material buildup inside the valve housing that can occur during operation. These features include: angled surfaces and rounded edges inside the housing to eliminate dead zones and ensure optimal material flow; factory-applied internal surface coatings, such as tungsten, to prevent surface wear imperfections where material can buildup; glandless, sleeve-style shaft seals that prevent contaminant migration into the housing; and stainless steel housings cast in North America to ensure superior strength in the composition and solidification of the housing’s metallurgy. The stainless steel housings are then CNC-machined to precise tolerances; and, with internal surfaces polished to a No. 4 finish, the ACS Valves design eliminates internal crevices and joints, common with conventional cast housings and bolt-together designs, where contaminants can accumulate. By reducing the accumulation of material inside the valve during operation, the ACS Valves Run-Clean™ Series reduces total time for cleaning, validation, and inspection of the valve, and therefore, speeds the return to service of the valve.
