Airlock is available with either round or square flanges with outboard bearings and gland-type shaft seals. Airlock's rotor options include open end, closed end, fixed or adjustable blades, bevel-edged blades, scalloped pockets, reduced capacity, teflon-coated blade, and blades with flexible rubber tips. Airlock sizes range from 3.5 to 36 inches, and it complies with NFPA 69 standards. Rotolok, Monroe, NC 704-282-4444 www.rotolok.com Rotary Valve RotoVal Hypergienic rotary valve is for food, pharmaceutical, and other sanitary processes. Valve is machined from solid stainless steel in a propri- etary, non-porous, self-draining design with polished surfaces to eliminate contamination from trapped materials and the associated bacterial growth. Valve is available in two designs offered with FDA-compliant, double lip seal assembly, and optional pharmaceutical seals to ensure secure connec- tions between the valve, removable end covers, and inlet and outlet. Gericke USA, Somerset, NJ 855-888-0088 www.gerickegroup.com Rotary Airlock Rail Valve MZC rotary airlock rail valve is suitable for applications requiring regular valve maintenance. Valve features an easily detachable rotor, which facil- itates thorough cleaning and inspection and quick changeover between production runs. Valve's rail support system ensures accurate alignment during rotor and end cover removal. Valve's T-bolt extraction mechanism prevents rotor damage and ensures tight clearances. Valve's rails are cast directly into the housing, eliminating external edges and crevices where contaminants can accumulate. Valve comes in USDA-accepted, ATEX- rated, and NFPA 69-compliant versions. DMN, West Memphis, AR 870-733-9100 www.dmn-inc.com Tapered Rotary Airlock Valve SR tapered adjustable rotary airlock valve features a tapered rotor design that allows for rotor clearance adjustment without rotor removal. Unit's design can be used to compensate for temperature, wear, or material vari- ations. Unit's adjustable rotor clearance can help minimize gas losses in a pneumatic conveying system. Unit is designed for use under gravity, pres- sure, and vacuum conditions. Unit's tapered rotor also simplifies teardown and reassembly. Bush & Wilton, Charlotte, NC 704-573-6858 www.bushandwilton.com
