Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your PPOZYLPC MAC 3 Port Electronic Boost Control Solenoid Valve, model 35A-ACA-DDBA-1BA. This valve is designed for precise control of boost pressure in turbocharged applications, featuring a durable brass silencer and compatibility with PC6mm tube connections. Please read this manual thoroughly before use to ensure safe and efficient operation.
Safety Information
- Electrical Safety: Ensure all electrical connections are made by a qualified professional. Disconnect power before installation or maintenance. The valve operates on 12V DC.
- Pressure Safety: This device operates with pressurized air. Always relieve system pressure before attempting any installation, removal, or maintenance. Wear appropriate personal protective equipment.
- Installation: Incorrect installation can lead to system malfunction or damage. Consult a professional if you are unsure about any installation steps.
- Operating Environment: Do not expose the valve to extreme temperatures, corrosive chemicals, or excessive vibration.
Product Overview
The PPOZYLPC MAC 3 Port Electronic Boost Control Solenoid Valve is a high-performance component designed to regulate boost pressure. It features three ports for pneumatic connections and an electrical coil for electronic control. The included brass silencer helps reduce operational noise, and the PC6mm tube fittings ensure secure connections.

Setup and Installation
Proper installation is crucial for the performance and longevity of the solenoid valve.
- Mounting: Securely mount the valve in a location free from excessive heat, vibration, and moisture. Ensure easy access for future maintenance.
- Pneumatic Connections:
- Port 'P' (Pressure/Inlet): Connect this port to the pressurized air source (e.g., turbo outlet or boost source).
- Port '1' (Wastegate/Actuator): Connect this port to the wastegate actuator or boost control diaphragm.
- Port '2' (Vent/Exhaust): This port is typically vented to atmosphere or connected to the intake side of the turbo for recirculation. The brass silencer is installed on this port to reduce noise.
Ensure all PC6mm tube connections are secure and leak-free. Use appropriate tools for tightening fittings without over-tightening.
- Electrical Connections: Connect the valve's wiring to a 12V DC power source controlled by your boost controller or engine management system. Observe correct polarity if specified by your boost controller. The valve consumes 5.4 Watts.

Operating Instructions
The 3 Port Electronic Boost Control Solenoid Valve operates by receiving an electrical signal (typically a Pulse Width Modulation, PWM signal) from a boost controller or engine management system. This signal modulates the valve's internal mechanism, controlling the amount of pressure directed to the wastegate actuator, thereby regulating the turbocharger's boost output.
- Ensure your boost controller is properly configured for a 3-port solenoid valve.
- Follow the specific tuning guidelines provided with your boost controller or engine management system for optimal performance.
- Monitor boost levels carefully during initial setup and tuning to prevent over-boosting.
Maintenance
Regular maintenance ensures reliable operation and extends the lifespan of your solenoid valve.
- Inspection: Periodically inspect the valve, tubing, and electrical connections for any signs of wear, damage, or leaks.
- Cleaning: The brass silencer may accumulate debris over time. If performance degrades or noise increases, carefully remove and clean the silencer. Ensure it is dry before reinstallation.
- Electrical Connections: Verify that electrical connections remain secure and free from corrosion.
- Tubing: Check pneumatic tubing for kinks, cracks, or hardening. Replace damaged tubing promptly.
Troubleshooting
If you experience issues with your boost control system, consider the following:
| Symptom | Possible Cause | Solution |
|---|---|---|
| No boost control / Constant low boost | Incorrect wiring; No power to valve; Valve stuck closed; Leaks in pneumatic lines. | Check electrical connections and power supply (12V DC); Verify valve operation (audible click when powered); Inspect all pneumatic lines for leaks. |
| Inconsistent boost / Boost spikes | Incorrect boost controller settings; Valve malfunction; Restricted pneumatic lines. | Review boost controller settings and tuning; Check valve for smooth operation; Ensure pneumatic lines are clear and unobstructed. |
| Audible air leak | Loose fittings; Damaged tubing; Faulty valve seal. | Tighten all PC6mm tube fittings; Inspect tubing for damage and replace if necessary; If leak persists from valve body, contact support. |
