Product Overview
The SMC VQ7-8-FG-D-3NR is a high-performance pneumatic solenoid valve from the SMC VQ7 series, engineered for precise directional control of compressed air in industrial automation and process systems. This valve utilizes a spool-and-sleeve actuation principle, where an electrical solenoid pilot signal shifts the internal spool to direct airflow between supply, exhaust, and cylinder ports. The VQ7 series is recognized for its compact body, high flow capacity relative to its size, and rapid response characteristics, making it a preferred choice for demanding pneumatic circuits requiring reliable, repeatable switching. The “3NR” designation indicates a 3-position closed-center configuration with non-locking manual override, while the “FG” and “D” codes specify the electrical connection style and pilot voltage rating respectively. This valve serves as a critical control element in pneumatic valve manifolds, directing actuator motion in packaging, assembly, and material handling equipment.
