72 Series
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.

35 Series
Small 3-Way Valves
The MAC 35 series is a direct solenoid operated 3-way poppet valve. It features a short stroke solenoid, a balanced poppet and powerful return spring. These features translate into high shifting forces, fast consistent response times, and long life. Our unique balanced design means versatility in piping - the valve can be configured as a 3-way or 2-way - normally closed or normally open or can be used for vacuum, diverter or selector applications.
