The MAC 38 Series is a high flow 16mm 3-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 balanced design in the pilot means shifting forces are consistently high and response times are repeatable regardless of inlet pressure fluctuations.
