    52 Series

    The MAC 52 Series is a 3-way balanced spool valve pilot operated by a small direct operated 4-way solenoid valve - a one-off in valve manufacturing.  The 4-way pilot means a low minimum operating pressure - no pistons - and minimal resistance to shifting.  The balanced design in the pilot means shifting forces are consistently high and response times are repeatable regardless of inlet pressure fluctuations.  For information regarding certifications (such as UL, CSA, RoHS and CE) please visit the Get Support pages on our website.

    54 Series

    The MAC 54 Series is a 3-way balanced spool valve piloted by a small direct operated balanced poppet valve.  This is an extremely versatile valve: 1. It can be converted for use in vacuum.  2. It can be changed from a Normally Closed function to a Normally Open function.  Huge flow in a compact package size is the best way to describe this valve series.  3. It also can be converted to a remote air operated valve by removing the solenoid pilot assembly - just to name a few.  For information regarding certifications (such as UL, CSA, RoHS and CE) please visit the Get Support pages on our website.
