- VERY FEW PARTS
- LONG LIFE LIFTING SOLENOID
- ONE PIECE POPPET / ARMATURE
- BALANCED DESIGN

The BV21 represents yet another evolution in air valve technology from MAC. The Bullet Valve® utilizes “lifting” solenoid technology. The MAC “lifting” configuration is unique, however, in that the valve maintains a balanced design – a signature feature of a MAC valve – shifting forces are consistently high and response times are repeatable regardless of inlet pressure fluctuations. 2-way and 3-way configurations of the BV21 cartridge are available.
