MAC solenoid valve 56 seriesThe MAC 56 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 a Normally Closed function to a Normally
Open function by simply rotating a function plate between the pilot and 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.
