Introduction
II. MAC’s 4-WAY PILOT SYSTEM – Maximized Shifting Forces
The balanced 4-way pilot valve provides maximum shifting forces in both directions by supplying air alternately to each end section of
the spool, similar to double acting rodless cylinder. This system provides maximized shifting forces, equal forces at energization and
de- energization, with no resistance to shifting at either end. The result is increased shifting reliability and faster, more consistent
response times.
