48 Series
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.
