4 Port Boost Control Solenoid Features:

Our 4-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 4-port design works equally well in low boost applications and high boost. This differs from a traditional 3-port BCSV because it precisely directs pressure to the open and close ports of your waste-gate diaphragm. This allows much lower waste-gate spring pressure for better low gear boost control and perfect high gear, high boost control.

• 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.
