400 Series
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.

24 Series
Small 4-Way Valves
The MAC 24 Series is a compact - high flow - 10mm - solenoid pilot operated 4-way spool valve. The valve offers high flow not common for a valve of its size. The valve utilizes our new 8mm E-pilot with oval armature for maximized shifting forces in a small package size. The balanced design in the pilot means shifting forces are consistently high and response times are repeatable regardless of inlet pressure fluctuations.
