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.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
