ARO M313PD Air Valve

ARO M313PD MaxAir four-way, three-position pilot valve delivers precise air control for packaging and material-handling lines. With 3/8 in port size and NPT threads, this body-ported valve can be used as a standalone unit or manifold-mounted to control multiple actuators from a central location. It is pilot-operated (no electrical coil) with a closed-center spool and spring-centered operation, providing a defined rest state when all pilot signals are inactive. The MaxAir series emphasizes prelubricated-for-life reliability and a compact footprint while delivering notable flow for its size: Cv 1.65 and a flow rating of 61 SCFM. The valve tolerates a supply pressure range of 45 psi to 140 psi, making it compatible with common compressed-air systems used in packaging and material-handling environments, and it supports 4-way, 3-position configurations ideal for double-acting cylinders and air motors. It measures 6.475 inches in length and 1.811 inches in height, and weighs 2.2 pounds; port size is 3/8 in with 3/8 in NPT ports. Part of ARO’s MaxAir family, the M313PD combines compact size, robust flow capacity, and maintenance-friendly design for reliable, factory-floor performance.
