ARO K313TS Valve

The ARO K313TS is a K Series air control valve configured as a four‑way, three‑position unit with a spring‑center default and a treadle/manual actuator option, using 3/8" NPT ports for inlet and exhaust connections. The unit is built with an aluminum body and Buna‑N seals, featuring a hard‑anodized PTFE sleeve around the aluminum spool for durability and low friction; Viton seals are available for higher‑temperature applications. Weighing about 2.20 lb, the K313TS sits among ARO’s 5‑port, 4‑way valve family that offers port sizes from 3/8" up to 1" and multiple actuator styles, including the treadle/spring combination used on this model. The K Series is designed for packaging and air‑motor applications and is suitable for inline installation or mounting on manifolds, providing flexible control across a range of pneumatic circuits and actuation options.
