Ross Controls W7056A4332 Pneumatic Control Valve

Ross Controls W7056A4332 is a base-mounted pneumatic directional control valve from the W70/W74 family, engineered to route compressed air to actuators in automation systems. It carries a vacuum to 150 psig (0–10 bar) operating pressure rating and uses 3/4" NPT port connections, as indicated by the 3/4 NPT designation in the model. The W70/W74 series are base-mounted, 5‑way directional valves using either a spool or a poppet configuration, and this variant follows that form factor with standard NPT plumbing; across the series, base-port sizes range from 1/4" to 1-1/2" NPT, with BSPP options available on request. In Ross' numbering scheme, the internal function code supports 5/2 (3) or 5/3 (4) configurations depending on the exact full code, so W7056A4332 falls under one of those two common arrangements. Typical applications include controlling pneumatic cylinders and other actuators in manufacturing lines, packaging equipment, and material-handling systems, where compact base-mounted valves provide reliable directional control and straightforward integration into standard pneumatic circuits.
