ARO K313SD-120-A Industrial Pneumatic Solenoid Valve

ARO K313SD-120-A is a four‑way, three‑position pneumatic solenoid valve from ARO's K Series, designed to precisely control double‑acting cylinders and air motors in industrial automation. It uses 3/8" NPT ports for inlet, outlets, and exhaust and is actuated by dual 120 VAC coils, with a spring-centered center position for stable default state. The valve delivers a 2.3 CV flow rating, around 63 CFM, supports up to 150 psi, and operates from 0 to 180°F, making it suitable for high-speed, high-demand lines. Practically, the assembly measures roughly 12.68 inches long and 2.56 inches high, aligning with compact manifold installations and standard industrial piping for packaging, material handling, and general automation tasks.
