Humphrey's valves are a compact 1/8 inch ported 3- and 4-way, designed to work in a number of pneumatic applications. Valves from the same series can be mounted on a subbase or in-line, and 310 and 410 valves can go together on manifolds. They offer positive sealing, with a short-stroke balanced poppet design that doesn't need lubrication, is more tolerant of impurities in the air system and allows rapid cycling. The 310 series valves have a 0.12 Cv, and the 410 series has a 0.14 Cv. Both types have an air and inert gas rating from vacuum at 28 inches Hg to 125 psig. A continuous duty coil consumes 4.0W, comes in a range of ac and dc voltages, has flying leads and comes with a standard push, non-locking manual override. Options such as dc surge suppression and ac MOV, conduit connector with steel insert molded into the coil, plug-in, DIN-type connectors and a locking override are available. The 410 series can save space, weight and the cost of external flow controls with optional built-in flow controls.
One way to keep a Formula One racing team moving at breakneck speed in the pit and at the test facility is to bring CAD drawings of the racing vehicleís parts down to the test facility and even out to the track.
Most of us would just as soon step on a cockroach rather than study it, but thatís just what researchers at UC Berkeley did in the pursuit of building small, nimble robots suitable for disaster-recovery and search-and-rescue missions.
Design engineers need to prepare for a future in which their electronic products will use not just one or two, but possibly many user interfaces that involve touch, vision, gestures, and even eye movements.
