Norgren was challenged to develop a pneumatic valve system with innovative design features in order to distinguish it from similar type products already in the market. Design engineers needed to create a product with maximum flow within the smallest possible space at the lowest possible cost....

Pneumatic valves have come a long way since the development of the compressor over a century ago. Starting with large manual and mechanical valves, they migrated to individually wired electric solenoids and ultimately ended up with plug-into-the-base electronics allowing for a single multi-pin...

Determining flow capacity is a critical factor in valve selection. Directional-control valves are common in pneumatic systems. They control compressed-air flow to cylinders, rotary actuators, grippers, and other mechanisms in packaging, handling, assembly, and countless other applications...

Flow specifications based on Japanese test standards tend to overstate performance. Vice President for Research & Development Most design engineers select pneumatic control valves based on performance data published by the valve manufacturer. Usually the key performance factor is how much air...

Modified atmospheric packaging is a process where a product is placed in a tray, a vacuum is pulled to remove atmospheric air, gas is injected and the tray is sealed. This process extends shelf-life, enhances color and eliminates crushing....

...operating conditions of these valves in a device containing eight channels and eight valve diameters....

Look at flow coefficient, cylinder bore, and rod speed to best match pneumatic actuators and valves. In recent years, much discussion has centered on ratings (also known as capacity coefficients or flow factors) and whether or not American, European, and Japanese pneumatic-valve manufacturers rate...

...flow region. Confusion and misinformation seem to be the order of the day when it comes to rating pneumatic valves. For instance, in a recent MACHINE DESIGN article ( "Clearing the Air on Pneumatic Valve Ratings, " Oct. 5, 2000) the authors assert that flow specifications based on Japanese test...

Buses and RVs often feature a kneeling option that lowers the vehicle and eases the task of climbing on and off. But this typically forces the manufacturer to assemble an array of pneumatic valves, connectors, and other components into a customized system....

A newly developed pneumatic-control system provides an alternative to electrical or electromechanical motion control. The Pneumatic Control System (PCS) is a compact electronic controller with pneumatic valves that accurately positions an actuator rod or rotating shaft and holds it in position even...
