The 3-2/2 valve is for applications requiring one signal to operate three 2-way normally closed valves simultaneously. A single-solenoid air-pilot operator shifts a spool that opens or closes three sets of supply to ports. Mechanically linked via one spool, all three 2-way functions must shift at the same time and flow rate. Solenoid coils are guaranteed no burnout for the life of the valve.
In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
