44 Series
The MAC 44 Series is a direct solenoid operated 4-way – 10mm – poppet valve. A direct operated 4-way of this size with such high flow is unique to MAC due to patented design innovations. It features an oval armature in the solenoid, a balanced poppet and conical seats. These features translate into high shifting forces, fast consistent response times, high flow in a small package and long life.

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.

46L Series
Small 4-Way Valves
This new valve series utilizes the patented balanced lifting technology that was developed for the Bullet Valve®, and has been implemented in the 35 Series lifting and 46 Series lifting valves. By re-configuring the standard 46 Series push type solenoid construction to a lifting design while maintaining the balanced principles of MAC Valves, we have added the benefits of longer life and greater repeatability without sacrificing the technology that has made the 46 Series a market leader.
