SMC VT315-021G Pneumatic Solenoid Valve 3/2 Way

The SMC VT315-021G is a compact, solenoid-actuated pneumatic valve configured as a 3/2‑way device for directing compressed air in automation systems. In operation, energizing the solenoid shifts the internal spool to connect the pressure port to the output while venting the third port, creating two distinct flow states that provide straightforward on/off control of a pneumatic actuator. This part number identifies a dedicated SMC valve designed for reliable electrical actuation and space-efficient installation in control panels and machine enclosures where tighter packaging is essential. Use cases typically include small‑scale automation, line control, and other air‑logic circuits that require compact, dependable directional control of airflow.
