The MAC Advantage: ISO Valve Comparison Presentation

Posted by Kristin Sweeney on Wed, Nov 28, 2012 @ 09:39 AM

The above video demonstrates that all ISO valves are NOT created equal. Although the ISO standard calls for all manfacturers to fit on a common interface/base, that is where the commonality ends.

The MAC Advantage is reflected here in the number of cycles achieved within a given period of time. This is a direct result of higher shifting forces, lower internal frictional character, faster response times and larger flows in a given size.

3 Things To Look For When Selecting a Pneumatic Valve

Posted by Kristin Sweeney on Tue, Jul 05, 2011 @ 08:48 AM

Selecting the right pneumatic valve that can be beneficial to your machine requires 3 important things:

  1. high shifting forcesShifting forces:  In order to ensure a reliable valve, high shifting forces are required.  A valve with higher forces will shift through more contamination throughout its life.  How can you determine shifting forces?  Speed.  Higher forces result in faster speeds.                                       Fast valve = High shifting forces = A more reliable valve.
  2. balance designBalance:  In many applications, it is critical that the same result happens each time a valve shifts.  A filling machine must fill bottles to the same levels.  A glue dispensing gun must place a glue dot in the same place every time.  A sorting machine must eject bad parts consistently.  In order to do this, a valve must be repeatable at all pressure levels.  This is especially important to compensate for variations in pressure during normal plant operations.  This attribute is referred to as a “balanced design".                                                                 Balanced design = Repeatability = A more reliable valve.
  3. orifice sizeOrifice size:  The larger the orifice in the valve is, the less likely the valve is to get clogged and not function.  Try looking at filter specs to see where manufacturers believe the problems start for their orifice.  For instance, a 40 micron spec would indicate a larger orifice than a 5 micron spec.

Shifting forces, balance, and orifice size are all important in selecting the right product for you.  Contact a MDN Sales Engineer to discuss these factors and for a free product demonstration!
