The new MAC Bullet Valves represents yet another evolution to air valve technology from MAC Valves, Inc.  This innovative design is unprecedented in the market in its ability to provide speed, repeatability, long life and high flow in a unique cartridge package (see example below).  Available in 9mm, 10mm, and 14mm diameters (both 2-way and 3-way configurations), the Bullet Valve? utilizes a patented lifting solenoid design.  The MAC lifting solenoid is unique, in that the Valves maintains a balanced design - a signature feature of a MAC valve.  Thus, shifting forces are consistently high and response times are repeatable regardless of pressure fluctuations.
