SMC VFA5120-03N 5 Port 2 Position Pneumatic Valve

The SMC VFA5120-03N is a five-port, two-position air-piloted valve designed for compact pneumatic circuits that demand high flow from a single unit. This VFA-series valve is air operated and uses an internal pilot to switch states, making it well suited for installations where electrical actuation is impractical. The unit is body-ported with 3/8 in NPT ports and female threads, enabling straightforward integration with standard pneumatic manifolds; its overall dimensions are 45 mm in height, 110 mm in length, and 32 mm in width. It supports an operating pressure range of 0.15 to 0.9 MPa (about 1.5–9 bar) and provides Cv values of approximately 2.4 for P→A/B and 2.9 for AB→EA/EB, delivering robust actuation for cylinders and other air-powered devices. Typical applications include controlling double-acting cylinders in automation lines and serving as a compact pilot valve within a manifold system, where a reliable, air-driven solution is preferred over electric solenoids.
