48 Series
Small 4-Way Valves
The MAC 48 Series is a high flow 16mm 4-way spool valve with a unique integral four way pilot. The short stroke solenoid utilizes an oval armature for maximized shifting forces in a small area. The 4-way pilot means a low minimum operating pressure - no pistons - and minimal resistance to shifting. The balaced design in the pilot means shifting forces are consistently high and response times are repeatable regardless of inlet pressure fluctuations.

900 Series
Small 4-Way Valves
The MAC 900 Series is a versatile 4-way solenoid piloted spool valve. This series features our balanced poppet in the pilot and an air/spring return for consistent shifting regardless of inlet pressure fluctuations. Versatility in piping means the valve can be piped as a 4-way, 3-way, 2-way, normally closed or normally open or can be used for vacuum, diverter or selector applications. Our one piece bonded seal spool means longer life and easy maintenance. For information certifications (such as UL, CSA, RoHS and CE) please visit the Get Support pages on our website.
