The Uncrushable Reliability of Magnetic Actuation

Hydraulic press is unable to crush MagDrive magnets this!


This video represents one of the great things about the age in which we live. You can find anything on YouTube! If you haven't seen these videos of a hydraulic press crushing random household stuff, you owe it to yourself to spend ten minutes watching the awesome power of thousands of pounds of pressure making confetti out of everyday items. 

At MagDrive, we're often asked about the reliability of magnetic actuation. After all, when magnets are mentioned most of us think about kids drawings on the refrigerator being held up by the magnet we bought on our summer vacation to Yellowstone National Park. 

At a conference in Austin, Texas earlier this year, our team was asked about the reliability of magnets again and again. So, what does this have to do with hydraulic press videos? 

Our team recently came across this great video showing 9,000 pounds per square inch being applied to a magnet in a hydraulic press. And it didn't break! If you'd like to read more about this, check out this article in Popular Mechanics

At MagDrive we're using rare earth magnet that are incredibly strong. We can create thousands of pounds of torque to drive industrial valves of any size. Through magnetic coupling (two magnetic arrays linked together through a solid wall), we can generate powerful valve actuation capabilities, while also eliminating a leak path to the outside world. 

We're proving reliability of MagDrive fitted valves through tests like the API 6FA, where MagDrive actuated 44,000 times after the product was heated to 1800° F (982° C). Strong and reliable. Welcome to the new category of magnetically actuated valves.
