Product Overview
The SMC VQ7-6-FG-D-3ZA03 is a high-performance pneumatic solenoid valve from the VQ7 series, engineered by SMC Corporation for precision directional control of compressed air in industrial automation systems. This valve operates on a spool-and-sleeve actuation principle, utilizing an electrical solenoid pilot to shift the main spool and direct airflow through the designated port configuration. The VQ7 series is recognized for its compact body design, high flow capacity, and rapid response times, making it a critical control component in pneumatic circuits requiring reliable and repeatable directional switching. The “FG” designation indicates a specific body and port configuration, while the “D” denotes the solenoid actuation type, and “3ZA03” specifies the electrical connection and voltage characteristics. This valve is designed for direct integration into SMC manifold assemblies or standalone panel mounting, providing versatile installation options for complex pneumatic control architectures.
