ASCO 4FC3 is a 2‑way direct‑acting pneumatic solenoid valve designed for on/off control of compressed air in compact automation circuits. The standard configuration uses 1/2" NPTF ports and has a Cv of 6.0, delivering reliable flow characteristics in small-diameter pneumatic lines, with a bottom-port variant (4FC3B) available for alternative piping layouts. This direct‑acting, two‑position valve provides fast actuation for general‑purpose pneumatic control in industrial equipment.
