High Speed

High Speed

There are many industry sectors that require repeatable, high speed valve operation including dispensing, sorting, textile manufacture and surface mount machinery to name a few.

MAC Valves is the leading manufacturer of high speed valve technology in the world. Through their constant end user interaction and pioneering technical development, MAC and PSI have helped many companies enjoy the benefit of more accurate valve technology. Whether it has reduced the quantity of re-sort required or improved the response and accuracy of a hot melt glue dispenser, regardless of the differences in application, the benefits of low cost of ownership and accurate operation are shared.

All of these applications require high repeatability, but what is it that causes a system to be erratic? Some will argue that it may be the programming, actuators or the electronics, the truth is, in most cases its down to the air valve. Many people would view the air valve that is at the heart of their system, to be a commodity item and if its not a MAC valve then they would be right, because all valves are made the same way, unless it is a MAC valve.

Surface Mount MachineAir fluctuation is a major problem in all applications. The change in air pressure changes the force to the valve. If the pressure drops, there is less force acting upon the unbalanced poppet and therefore it will take longer to unseat. If the pressure bounces back and forth, then so does the response time of the valve. Hence, no repeatability. Your welding will not achieve the correct pressure, your sorting will not sort the correct part, and your pick and place will crash. Repeatability is a must.

If your application requires repeatability, consistent response time, high speed; which most do, then a Mac Valve is your solution.


Through their development of balanced poppet and low resistance coil technologies, MAC Valves have produced the most repeatable, high speed valves in the industry. The latest technologies are capable of achieving operation at 2000Hz. Contact us about our demonstrations that show not only how a MAC Valve functions, but also how the valves that you are currently using operate. We can also show you direct comparisons of your current valve against the MAC Valve alternative, in operation, using our Travelling Lab Demonstration cases.
