67 Series
The MAC 67 Series is a 3-way balanced spool valve piloted by a small direct operated 4-way solenoid pilot – a one-off in air valve manufacturing. The 4-way pilot means a low minimum operating pressure – no pistons or springs – 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.

57 Series
Large 3-Way Valves
The MAC 57 Series is a 3-way balanced spool valve piloted by our 200 series (which means this large 3-way valve can also be ordered with the 200 series Hazardous Location version as a pilot - giving it the same standard). 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 by simply rotating a function plate between the pilot and the main valve bodies. 3. It can also be converted to a remote air operated valve by removing the solenoid pilot assembly - just to name a few.

55 Series
Large 3-Way Valves
The MAC 55 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 an Internal Pilot to an External Pilot function by simply rotating the adaptor between the pilot and valve main bodies. 3. It can also be converted to a remote air operated valve by removing the solenoid pilot assembly - just to name a few.
