Rotary Airlock Valves Enable Access To Internal Housing
ACS Valves introduces a new line of cast iron rotary airlock valves, featuring the ACS RotorRail which enables tool-less access to the rotor and all internal surfaces of the housing. It is designed to help avoid time-consuming disassembly of the rotor and prevent removal from service of upstream or downstream equipment commonly associated with standard valve configurations.
The RotorRail allows rotor realignment during reassembly, which reduces axial shaft movement, bearing wear, seal leakage, and premature, uneven rotor vane wear. The inlet/outlet seal is achieved using the standard 8-vane rotor design, which reduces excess pressure loss through the system, ensures cost-efficient upstream and downstream material management, and reduces process energy consumption.
The valves are available in sizes from 6 to 16 inches, with pressure differentials up to 15 PSIG, and temperature tolerance up to 500 degrees Fahrenheit. 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.
