The Generation 3.0 valve module with inputs has one valve, which can be a single or double solenoid, directly linked to the DeviceNet Network. The serial addressable, self-contained module has two 24-VDC valve outputs capable of handling a wide range of well-established valve designs with flow rates from 0.6 to 13 Cv. Control of two 24-VDC external inputs is also provided. Parker Hannifin Corp, Automation Group, Pneumatic Div, 257 Huddleston Ave, Cuyahoga Falls, OH 44221. 330-923-5202.

8501A807 Pneumatic manifolded assemblies and power packs. These compact assemblies increase system reliability by minimizing possible leak paths and reducing part counts. Fittings and hoses are eliminated by using plug-in pressure and vacuum regulators, manifold mount three- and four-way solenoid valves and a compressor vacuum pump. Check valves, relief valves, filters, dryers, heat exchangers and stored gas supplies can be incorporated into customized packages for applications in medical and analytical instruments. Aerodyne Controls Corp, 30 Haynes Court, Ronkonkoma, NY 11779. 516-737-1900.

8501A813 Flexible air hose. This flexible hose and duct has a smooth interior that does not restrict flow. It's manufactured without glues, solvents or chemicals that delaminate and leak. The seamless hose can be extruded in sizes ranging from 10 mm to twelve inches in diameter. Material choices include PVC, urethane, polyethylene and thermoplastic rubber in clear or colors. Custom fittings are available. Hi-Tech HoseInc, Seven Opportunity Way, Newburyport, MA 01950.

8501A809 Compressed air controller. This flow controller for air compressors separates the supply side from the distribution side. It creates storage within the receiver tank by accumulating compressed air without delivering it downstream. Air pressure only increases upstream of the air receiver while the flow controller delivers the needed flow downstream at a constant pressure. Actual flow demand is reduced by eliminating artificial demand and reducing leakage. Kaeser Compressors, PO Box 946, Fredericksburg, VA 22404. 540-898-5500.

8501A815 Lifting cylinder. The HS is a high speed lifting cylinder used for handling paper and other porous materials. Unlike other vacuum cups that draw pressure through the top sheet onto the second and third sheets, the HS grips the top sheet and removes it before vacuum pressure reaches the next sheet down in the stack. The cups have inner supports that prevent the sheet from drawing into the vacuum hole. Schunk, 211 Kitty Hawk Dr, Morrisville, NC 27605. 919-572-2705.

8501A810 Check-valved vacuum cup. These 2- and 3 3/8-in. vacuum cups with built-in check valves are designed for applications where multiple vacuum cups are connected to a main vacuum line, but only a portion of the cups are activated at one time. The check valves prevent inactivated cups from leaking atmospheric air into the system, thereby reducing the vacuum level in the main line. The valve stems are made from black nylon. Teknocraft Inc, 425 West Dr, Melbourne, FL 32904. 407-729-9634.

8501A816 Diaphragm valves. These air-operated diaphragm valves have no wetted elastomers. They also have a patented safety vent that provides advance visual warning of seal failures while permitting the valve to continue functioning until maintenance can be scheduled. Standard body material is PVC, but it is also available in polypropylene, Teflon and PVDF. Plasto-O-Matic Valves Inc, 1384 Pompton Ave. Cedar Grove, NJ 07009-1095. 201-256-3000.
