3-port boost control solenoid valve is designed to target a clearly defined boost curve and improve boost responses, and in some cases with a soft WG spring – quicker spool. The 3- port design works equally well in low boost applications and high boost.  This allows much lower waste-gate spring pressure for better low gear boost control and perfect high gear, high boost control.

3- Port Boost Control Solenoid Features:
A soft waste-gate spring will enable much higher boost levels
Better spool-up and mid range power
Better duty cycle control
Solenoid is normally closed so that on failure you will run off the waste-gate spring only – to prevent over-boosting.
1/8th NPT fittings, easily adapted to AN fittings.
