169-070 Mac Solinoid (Boxxer Maxx CDS) Equipment Maintenance Can I clean it insteadOverview Primary vacuum solenoid valve three way, normally closed, Viton seal, 12 V DC. HydraMaster part number 000 169 070, listed as Valve, Primary Vac. Solenoid. Commonly called the MAC solenoid after its manufacturer. It is a pneumatic control valve, not a water valve. It switches the vacuum or air signal that operates the machine's air cylinders which is why a fault here shows up as something mechanical refusing to move rather than as a leak.
