New valve family opens additional application possibilities
By Paul J. Heney and Mary Gannon Cincinnati-based Clippard Instrument Lab created its EV line of valves in 1973. The company’s workhouse pneumatic valves have seen a lot over their lifetime—video games like Pong have evolved into lifelike realty games and mobile phones the size of loaves of bread are now compact, thin devices that […]
Pneumatics through the ages—a timeline of evolution
So much of today’s modern machinery utilizes some form of pneumatic component within its makeup and function. Yet it can be argued that the majority of people know little about the industry and how components have evolved into being essential elements the likes of jet engines. To understand how pneumatic components have become important parts […]
Pilot valve series from Humphrey act as a pneumatic interface
Humphrey Products Co., Kalamazoo, Mich., introduces the A10 and A15 Series pilot valves—miniature direct-acting solenoid valves that are perfect as a high value pneumatic interface, linking PLCs and air piloted pneumatic, or process control work valves. Configured as compact 3-port sub-base mount, the A10 and A15 pilot valves feature low power consumption, excellent flow, and […]
