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.

400 Series
Small 4-Way Valves
The MAC 400 Series is a 4-way spool valve pilot operated by a small direct operated 4-way solenoid valve - a one-off in air 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.
