The MAC 72 Series valve is a 3-way balanced P.O.P. (Pilot Operated Poppet) valve – pilot operated by our Bullet Valve® technology – patents pending. 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 – as shifting forces are consistently high and response times are repeatable regardless of inlet pressure fluctuations.
