Description These valves are genuine MAC, high quality PWM (pulse width modulated) 12v boost (actuator) control solenoids. The valve is compatable with and is the same type used with AEM, some Turbosmart, Hondata and many other boost controllers and systems. The kit comes with 2x 4mm barbs for hose connection. The 3rd port is typically a vent port. This solenoid can be used directly with Adaptronic and many other engine management systems that have a wastegate control feature designed to connect with a PWM valve. Specification: Optimal operating frequency: 25-50hz Max pressure: 120psi Usable duty: 10-90% Supply: 12vdc Typical installation:
