The AIRMIXS 4H430-15S is a heavy-duty, high-flow 5-port, 3-position (5/3-way) hand-lever-operated directional pneumatic control valve equipped with a closed-center spool and a self-centering spring return mechanism. Designed for high-volume airflow and precise intermediate positioning of large double-acting pneumatic cylinders, the spring-loaded handle automatically restores the valve spool to its neutral center position when released. In the center position, all ports are blocked to lock air pressure inside the lines, holding heavy cylinders safely mid-stroke. Built with a robust anodized aluminum body, low-friction internal seals, and full 1/2" connection ports, it ensures dependable operation and maximum pneumatic efficiency in demanding industrial machinery and automation systems.
